3. Operation & Instruction：

Connect the PCB to battery pack as shown in following picture.
3.1 Please connect PCB to battery first，then connect battery pack to the load,otherwise the PCB will be locked.

3.2 When install PCB on battery, if there is a fuel gauge on PCB, please disconnect
fuel gauge first, otherwise the PCB will be locked.

3.3 If you want to install a fuel gauge to monitor the battery’s voltage, connect ourfuel gauge (Part No: FG-MH30S) in fuel gauge socket, as shown below.

3.4 If the PCB is locked, the output voltage can be measured from OUT+ and OUT-,
but no output current. There are two ways to unlock the PCB:
A. Use a 36V NiMH charger to charge the battery, charging current should lessthan 7A. The PCB will be unlocked in several seconds.
B. Disconnect any load, include fuel gauge. The PCB will be unlocked in several
seconds.
3.5 The PCB has about 1.5mA consumption in idle status, so please charge the battery
pack immediately after use, or charge the battery periodically to maintain the battery
pack, otherwise the battery may be damaged. For example, for 3Ah capacity battery
pack, it should be recharged every 2000 hours (83days). You can calculate by using
the following formula
Days = battery capacity (mAh) / 1.5mA
3.6 Do not charge or discharge battery pack with PCB over 7A.
damaged due to over current.

The PCB will be

3.7 Over discharging or battery’s voltage<30V will lead to PCB locked. Charge thebattery immediately.
3.8 60oC thermostat should be put it in suitable position which is most possible catchthe highest temperature in the battery pack.

4. WarningCustomer should be professional in NiMH/NiCd battery pack to use the PCB.
Misusing PCB may cause battery damage or explode.
Don't use this PCB with Li-Ion / LifePo4 battery packUse for 36V NiMh/NiCd pack ( 30 cells 1.2V/cell) only.
Since this PCB does not have over-charge protection function, must use our 36V
NiMH/NiCd smart charger to recharge battery pack.
