EP 24 - Building a 2P10S Lithium Ion Battery Pack
Channel: Dielectric Videos
Date: 06/03/2017

Today I construct a 2P10S (2 parallel - 10 series) lithium ion battery pack. This battery pack employs the LG HG2 3000 mAh 18650 cell, and is constructed using desoldering braid. This battery pack is designed to perform in a hoverboard and is rated for 15 amps continuous discharge and up to 20 amps peak discharge. Total pack voltage range is 29-42V, and nominal capacity is 6000 mAh. The pack is internally fused at 25 amps.

Disclaimer: My experience building battery packs is limited, so I may make mistakes in this video. Additionally, desoldering braid is not rated for electrical continuity and is not recommended for use in battery packs without adequate testing. Spot welding should be preferably used to connect cells rather than soldering in order to reduce thermal stress when possible. Perform any actions seen in this video with proper equipment and at your own risk.
