    Voltage drop at Daly BMS 4S 12V 200A Lifepo4

    The voltage drop is because the MOSFETs are switching off without any notice. The problem is that Daly BMS is not tolerant towards disturbances coming from other units connected to the same 12V. By using some capacitors and ferrits I was able to make the problem disappear. Daly should really...

    Voltage drop at Daly BMS 4S 12V 200A Lifepo4

    I measure the voltage drop directly at the BMS between B- and P- with nothing else in between. If I discharge less than about 7.7A from battery then the BMS have just 3 mV voltage drop between B- and P-. If I discharge more than 7.7A then there is a voltage drop of 0.6V between B- and P-...
