Overkill BMS and xiaoxiang software are giving funny readings sometimes. I charge my 24 volt 100ah battery using my growatt solar inverter. After it's all charged, and in about 4 hours (edit: with the inverter off and no usage) , I look at the app and it's showing 65% capacity. Seemed odd so I fired everything back up and plugged the inverter in to charge the battery. Within 30 minutes it's balancing and drawing only an amp or so. Everything looks good I shut off the inverter , switch the battery cutoff to the inverter off, check capacity all good, switch off the bms. I fire everything back up and it's showing 62-68% capacity. It's obvious that the battery was not at 65% the first time as it charged back to 100% so quickly. When I plug it in to charge I have it limited to 18amps. I've done a capacity test and everything is fine. Why am I getting the odd readings now and then? Just curious . Thanks. K
