Obvs they were below nominal, I've found charging them to around 3.5V with a smart charger set to NiMh or NiCad works (connect directly to the cells, bypassing the BMS obvs). Then finish the charge on LiFePo4 setting (the BMS will pick that up) or the charger that came with the scooter. There will be a reduction in capacity, & this doesn't always work, but I've had a lot of success with this method. An interesting look inside a TGV, they've been around a while.

@@skysurferuk you could technically do this, but the cells form dendrites inside them, a chemical change, that isn't reversible, and this really increases the risk of fire and danger, plus high IR etc. I just wouldn't be comfortable putting a suspect pack like that into a Customers house - perhaps with one cell for a flashlight or something it would be fine, but a whole pack - I just wouldn't be happy unfortunately!
