Product Description
3.7V lithium battery protection board overcharging over discharge current of 2A apply lithium polymer battery
Description:
- This Board is used to protect lithium cells from Full Discharge, Over-Charging, Over-current and Short Circuit
- Suitable for Lithium Batteries with nominal voltage of 3.6V, 3.7V, 3.8V and charge up to 4.2V per cell
- Need basic soldering skills to wire the board
- Input voltage: 4.2V regulated from Constant Current and Constant Voltage source
- Board is very small – 22x4x3mm
Welding points:
B+ : Battery Positive
B- : Battery Negative
P+ : Charger/Load Positive
P- : Charger/Load Negative

Notes:
* Board is using DW01-P Chip to control the cells with 1x FS8205A MOSFETs. I found the datasheets and put them above.
* After connecting the cells may need to connect the charger to activate the board
* Before connecting cells in parallel, equalize the voltage with 1 ohm resistors between. May need from few minutes to few hours.
