Some details:
- Headway LiFePO4 10AH 36V battery
- About 2 years old now - so have been using it 2-3 days a week on average
- I think what happened is after the 2nd last ride it may not have charged, & I just took it out for the last ride & pretty much had drained the battery before getting home before I realized it
- When I try to charge it, by "Watt's Up" meter highlights it getting the expected voltage applied to it, however the currently flowing is really low, in fact this morning when I tried again it wasn't registering any current flowing
- I'll put some pic's of the battery below
Any tips on how to fault find, for example:
- is there a way with a multi-meter to go through cell by cell to try to tell if one cell is dead?
- how to tell if it's the BMS (e.g. so batteries ok but BMS not) - should I try charging directly to the cells bypassing the BMS? (note I charge via the BMS but discharge directly, as the BMS was hitting a safety cutover when it shouldn't be whilst I was riding - have been doing this for years)
