Jayzao Posted August 7 Posted August 7 When charging my ancient AirWheel, it no longer charges complete or "Fashion." After 90 minutes, I only get to "Funny, Forceful, and Free." Should I suspect the charger or the battery? I don't know that I want to sink money in a charger for this thing. Quote
alcatraz Posted August 8 Posted August 8 Leave it on the charger for a day or two. Use a multimeter because 4 leds aren't enough to see if there's slow progress. If you have dead cell groups then you shouldn't try to save them, but if they're only a bit low and the bms needs more time to sort them out you can just try to charge longer. Sometimes the bms can't balance low cells that are saveable. Then you need to manually balance them by opening up the pack. If you want the wheel back to 100% maybe swap the cells. Those packs aren't large so you probably just need 16-32 pieces of 18650 cells. It is however a bit tricky to spotweld them. 1 Quote
