Battery Future Acquisition Corp. 
 51 NW 26th Street, Suite 533 
 Miami, Florida 33127 

Re:    Initial Public Offering 

Ladies and Gentlemen: 
 This letter (this “Letter
Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and among Battery Future Acquisition Corp., a Cayman Islands exempted company
(the “Company”), and Cantor Fitzgerald & Co., as representative (the “Representative”) of the several underwriters (each, an “Underwriter” and collectively, the
“Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of up to 28,750,000 of the Company’s units (including up to 3,750,000 units that
may be purchased to cover over-allotments, if any) (the “Units”), each comprised of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Class A
Ordinary Shares”), and one-half of one redeemable warrant. Each whole warrant (each, a “Warrant”) entitles the holder thereof to purchase one Class A Ordinary Share at
a price of $11.50 per share, subject to adjustment as described in the Prospectus (as defined below). The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1 and a
prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange Commission (the “Commission”) and the Company has applied to have the Units listed on the New York Stock
Exchange. Certain capitalized terms used herein are defined in paragraph 13 hereof. 
 In order to induce the Company and the Underwriters to enter into the
Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each of Battery Future Sponsor LLC (the “Sponsor”),
Roth Capital Partners, LLC and its undersigned affiliates (collectively “Roth”), and the undersigned individuals and entities (each of the undersigned, an “Insider” and collectively, the
“Insiders”), hereby agrees with the Company as follows: 
  

	 	1.	 The Sponsor, Roth and each Insider agrees that if the Company seeks shareholder approval of a proposed Business
Combination, then in connection with such proposed Business Combination, it, he or she shall (a) vote any Ordinary Shares (as defined below) owned by it, him or her in favor of any proposed Business Combination and (b) not redeem any
Ordinary Shares owned by it, him or her in connection with such shareholder approval. If the Company seeks to consummate a proposed Business Combination by engaging in a tender offer, the Sponsor, Roth and each Insider agrees that it, he or she will
not sell or tender any Ordinary Shares owned by it, him or her in connection therewith. 

  

	 	2.	 The Sponsor, Roth and each Insider hereby agrees that in the event that the Company fails to consummate a
Business Combination within 18 months from the closing of the Public Offering (or up to 24 months from the closing of the Public Offering if the Company extends the period of time to consummate a Business Combination), or such later period approved
by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association (as it may be amended from time to time, the “Charter”), the Sponsor, Roth and each Insider
shall take all reasonable steps to cause the Company to (a) cease all operations except for the purpose of winding up, (b) as promptly as reasonably possible but not more than ten (10) business days thereafter, redeem 100% of the
Class A Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount
then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the
number of then outstanding Offering Shares, which redemption will completely extinguish all Public Shareholders’ (as defined below) rights as shareholders (including the right to receive further liquidating distributions, if any),

  

 and (c) as promptly as reasonably possible following such redemption, subject to the
approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in the case of clauses (b) and (c) to the Company’s obligations under Cayman Islands law to provide for claims
of creditors and in all cases subject to the other requirements of applicable law. The Sponsor, Roth and each Insider agrees to not propose any amendment to the Charter (i) to modify the substance or timing of the Company’s obligation to
allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within the required time period set forth in the Charter or
(ii) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides its Public Shareholders with the
opportunity to redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest
earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then outstanding Offering Shares. 

The Sponsor, Roth and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held
in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, him or her. The Sponsor, Roth and each Insider hereby further waives, with respect to any Ordinary
Shares held by it, him or her, if any, any redemption rights it, he or she may have in connection with (A) the consummation of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote
to approve such Business Combination, or (B) a shareholder vote to approve an amendment to the Charter (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial
Business Combination or to redeem 100% of the Offering Shares if the Company has not consummated a Business Combination within the time period set forth in the Charter or (ii) with respect to any other material provisions relating to
shareholders’ rights or pre-initial Business Combination activity or in the context of a tender offer made by the Company to purchase Offering Shares (although the Sponsor, Roth, the Insiders and their
respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the Company fails to consummate a Business Combination within the time period set forth in the Charter). 

 

	 	3.	 During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such
date, the Sponsor, Roth and each Insider shall not, without the prior written consent of the Representative, (a) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree
to dispose of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the
“Exchange Act”), and the rules and regulations of the Commission promulgated thereunder, with respect to, any Units, Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible
into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, (b) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units,
Ordinary Shares (including, but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by it, him or her, whether any such transaction is to be settled by delivery of
such securities, in cash or otherwise, or (c) publicly announce any intention to effect any transaction specified in clause (a) or (b) (each of the actions described in clauses (a), (b) and (c), a “Transfer”). Each
of the Insiders, Roth and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3, paragraph 7 or paragraph 8 below, the Company shall announce the impending
release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of such
press release. The provisions of this paragraph 3 will not apply if the release or waiver 

  
 2 

 
is effected solely to permit a Transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the
duration that such terms remain in effect at the time of the Transfer. In addition, during the period commencing on the date of commencement of sales of the Public Offering and ending 180 days after such date, Roth shall not sell, Transfer, assign,
pledge or hypothecate any of its Founder Shares or Private Placement Warrants (or any Class A Ordinary Shares underlying the Private Placement Warrants), or subject any of such securities to any hedging, short sale, derivative, put, or call
transaction that would result in the effective economic disposition of such securities, except as provided in FINRA Rule 5110(e)(1), which such restrictions shall not be subject to release or waiver, with or without the consent of the
Representative. 
  

	 	4.	 In the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial
Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”) agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever
(including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim
by (a) any third party for services rendered or products sold to the Company or (b) any prospective target business with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business
Combination agreement (a “Target”); provided, however, that such indemnification of the Company by the Indemnitor (i) shall apply only to the extent necessary to ensure that such claims by a third party or a Target do
not reduce the amount of funds in the Trust Account to below the lesser of (A) $10.20 per Offering Share and (B) the actual amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than
$10.20 per Offering Share is then held in the Trust Account due to reductions in the value of the trust assets, less taxes payable, (ii) shall not apply to any claims by a third party or a Target which executed a waiver of any and all rights to
the monies held in the Trust Account (whether or not such waiver is enforceable) and (iii) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended. The Indemnitor shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the
Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense. 

  

	 	5.	 To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional
3,750,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit, at no cost, a number of Founder Shares equal to 937,500 multiplied by a fraction, (a) the numerator of
which is 3,750,000 minus the number of Units purchased by the Underwriters upon the exercise (or expiration, if the over-allotment option is not exercised) of their over-allotment option and (b) the denominator of which is 3,750,000. The
forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder Shares will represent an aggregate of 20.0% of the Company’s issued and outstanding Ordinary Shares after
the Public Offering (not including Class A Ordinary Shares underlying the Private Placement Warrants (as defined below)). The Initial Shareholders further agree that to the extent that the size of the Public Offering is increased or decreased,
the Company will purchase or sell Units or effect a share repurchase or share capitalization, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the Initial Shareholders prior
to the Public Offering at 20.0% of its issued and outstanding Ordinary Shares upon the consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering, then (i) the references to 3,750,000 in
the numerator and denominator of the formula in the first sentence of this paragraph 5 shall be changed to a number equal to 15% of the number of Public Shares included in the Units issued in the Public Offering and (ii) the reference to
937,500 in the formula set forth in the first sentence of this paragraph 5 shall be adjusted to such number of Founder Shares that the Sponsor would have to surrender to the Company in order for the Initial Shareholders to hold an aggregate of 20.0%
of the Company’s issued and outstanding Ordinary Shares after the Public Offering (not including Class A Ordinary Shares underlying the Warrants or Private Placement Warrants). 

  
 3 

	 	6.	 (a) The Company’s officers and directors each hereby agree not to participate in the formation of, or
become an officer or director of, any other special purpose acquisition company with a class of securities registered under the Exchange Act until the Company has entered into a definitive agreement regarding a Business Combination or the Company
has failed to complete a Business Combination within the time period set forth in the Charter. 

 (b) The Sponsor, Roth and
each Insider hereby agrees and acknowledges that (i) the Underwriters and the Company would be irreparably injured in the event of a breach by the Sponsor, Roth or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7 and
8, as applicable, of this Letter Agreement, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition
to any other remedy that such party may have in law or in equity, in the event of such breach. 
  

	 	7.	 The Sponsor, Roth and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any
Class A Ordinary Shares issuable upon conversion thereof) until the earlier of (a) one year after the completion of the Company’s initial Business Combination and (b) subsequent to the Business Combination, (i) if the
closing price of the Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (ii) the date on which the Company completes a liquidation, merger, share exchange or other similar
transaction that results in all of the Company’s Public Shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up Period”). 

  

	 	8.	 The Sponsor, Roth and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants
or Extension Loan Warrants (or any Class A Ordinary Shares underlying the Private Placement Warrants or the Extension Loan Warrants), until 30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up
Periods”). 

  

	 	9.	 Notwithstanding the provisions set forth in paragraphs 3, 7 and 8, Transfers of Founder Shares, Private
Placement Warrants, Extension Loan Warrants and the Class A Ordinary Shares underlying the Private Placement Warrants and Extension Loan Warrants that are held by the Sponsor, Roth, any Insider or any of their Permitted Transferees (that have
complied with this paragraph 9) are permitted: (a) to the Company’s officers or directors, any Affiliate or Immediate Family Member of any of the Company’s officers or directors, any affiliate of the Sponsor or to any members of the
Sponsor or any of their Affiliates; (b) to the officers or directors of Pala Investments Limited (“Pala”), any Affiliate or Immediate Family Member of any of Pala’s officers or directors, any Affiliate of Pala or to
any equityholder of Pala or any of their Affiliates; (c) to the officers or directors of Roth, any Affiliate or Immediate Family Member of any of Roth’s officers or directors, any Affiliate of Roth or to any equityholder of Roth or any of
their Affiliates (d) in the case of an individual, by gift to any Immediate Family Member of such individual or to a trust, the beneficiary of which is an Immediate Family Member of such individual, an Affiliate of such individual or to a
charitable organization; (e) in the case of an individual, by virtue of laws of descent and distribution upon death of such individual; (f) in the case of an individual, pursuant to a qualified domestic relations order; (g) by private
sales or transfers made in connection with any forward purchase agreement or similar arrangement or in connection with the consummation of an initial Business Combination at prices no greater than the price at which the securities were originally
purchased; (h) in the event of the Company’s liquidation prior to the completion of an initial Business Combination; (i) by virtue of the laws of the Cayman Islands or the Sponsor’s limited liability company agreement upon
dissolution of the Sponsor; or (j) in the event of the Company’s liquidation, merger, share exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Class A
Ordinary Shares for cash, securities or other property subsequent to the Company’s completion of an initial 

  
 4 

 
Business Combination (each of the foregoing, a “Permitted Transferee”); provided, however, that in the case of clauses (a) through (f) or (h), these
Permitted Transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Letter Agreement (including provisions relating to voting, the Trust
Account and liquidating distributions). 
  

	 	10.	 The Sponsor, Roth and each Insider represents and warrants that it, he or she has never been suspended or
expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company

	 	12.	 The Sponsor, Roth and each Insider has full right and power, without violating any agreement to which it is
bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and,
as applicable, to serve as an officer and/or director on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer and/or director of the Company.
