2-Pack 70A Discharge Protection Boards, Compatible with DeWalt & Milwaukee 18V-20V MAX Batteries, Featuring Low Battery Discharge Cut-Off & Overheat Safety, BMS Only, Not for Charging

Introducing our BMS Protection Board: 【Installation and Connection】: Basic electronic knowledge is recommended for installing and connecting the BMS protection board. If you have any questions during installation or usage, please don't hesitate to contact us. 【Not for Internal Charging Protection】: The program written into the BMS protection board's connection hole is not intended for use with internal 5S charging protection boards. The BMS is solely designed for low-voltage discharge protection and cannot be modified for charging protection. 【Testing Considerations】: When testing the low-voltage interception protection function of the BMS, factors such as battery voltage drop and backflow should be taken into account. Different testing methods and voltage drop factors may result in slight variations in test results. 【Wide Compatibility】: The BMS has a broad range of applications. Most 18V and 20V batteries lack built-in discharge protection systems. If the BMS size fits the internal space of your device, it's ideal for adapting adapters, work lights, fans, and other devices compatible with 18V and 20V voltages. 【Package Contents】: You will receive 2x BMS Boards (Battery Not Included).
