Hey guys, I recently went a month long trip and when I came back my battery has been behaving weirdly. I’ll turn the board on and the percentage indicator says “0%.” Then, I plug it in and it instantly goes to 100%. After a few seconds that indicator slowly goes down to 0% again. Are my batteries toast?
EDIT: Using 5 2S 5000mah Turnigy batteries as well as a 10S Bestech BMS.
