## Customer Reviews

### ⭐⭐⭐⭐⭐ thank you
*by G***H on April 12, 2023*

thank you and thank you for the cheap beeing

### ⭐ Do not buy. Does not protect battery
*by U***I on December 29, 2024*

This BMS board does not work at all with my 4S LiFePO4 battery pack. The BMS circuit is supposed to disconnect the charging voltage when the voltage reaches the maximum value that can be applied to any cell in the battery pack. For a 4S LiFePO4 battery, the max voltage should not exceed about 14.4V. I expected the voltage on the battery terminal to stop increasing when the charging voltage reached that value. However the BMS did not shut off the charging voltage, but continued to rise. Luckily I limited the max charging voltage to 15V so the battery cells survived the small amount of overvoltage, especially since I was able to disconnect the charger quickly after observing the BMS fault. I tested a second board of the 4 included, but it has the same problem. Do not buy. There’s a danger this BMS will cause irreparable damage to your battery pack.

### ⭐⭐ Work ok but don't work for more than about 1.5Amp
*by T***. on January 9, 2024*

Dunno what's wrong with these things but they don't really work. Can't even drive a drill motor with no load.
