Hi everyone, battery is fully loaded, meter showed 28V on the output, then I opened the battery and completely disconnected BMS and reconnected again because I was suggested to do so to reset the battery since there is no reset button, anyway after reconnecting the baterry indicator shows the battery is completely discharched inspite the input to BMS is still 28V (now meter shows about 12V on the output). Putting the battery on the charger doesn't change anything. Anybody has any clue what happened? It seems that disconnecting the BMS was terrible idea
