Hey Matt, Thanks for the reply.
Scooter... as in low power motorbike with undersized tires. The current tires are on 12inch rims. No pedals. Not underbone style. The plan is for it to be cafe racer-ish when it is done.Scooter as in moped-style? Sit down feet together in front?
I don't think there is a BMS. I haven't taken the battery apart yet, but will start working on that soon. I'll take some pics of the electronic bits at some point.Sounds like your batteries are either shot, or the way they're being measured is shot. Or that one cell in the pack is gone.
Charge it up, test each cell.
Discharge it a bit, test each cell.
See if there's imbalance anywhere.
Presuming it has a BMS, imbalance probably then means the cell has more or less died and should be removed or replaced.
