I recently installed MiniBMS into my system. There are many mornings where I had to unplug the charger because the MiniBMS was beeping and the charger was still charging. Red LEDs are on. Sometimes the charger would shut off then a few seconds later turns back on. I've checked the voltage on the cells with red leds and they were between 3.8 and 3.9V So far no cells are damaged. My kit still functions to its full capacity. The HVC is wired up properly. I've seen it shut off the charger many times. The ignition wire to the BMS is also working properly.
