The 4s pack will start and run the small12vdc motor without issue. However, when the battery pack is connected to the BMS which provides cell balance and charging as well as protection) the motor will only momentarily start but immediately shuts down. I discovered that with two different BMS 4S boards had the same issue. Apparently, the di/dt in-rush current and the reverse spike caused the the BMS to immediately shutdown. Has anyone else experienced this and discovered a way around it? Ive tried Schottky diodes in reverse in an attempt to dampen the reverse current but its not reliable using even a PN junction diode.
Looking for comment regarding similar experience and mitigation suggestions.
Thanks
