I have a Lift E-Foil battery with the top of the case removed. The battery was practically new when it got a blinking red LED that could not be recovered. Lift replaced it under warranty. I’m not going to do anything with it, the cells all appear normal, it’s certainly good for parts. I didn’t damage anything when removing the case. You can pick it up in the LA area. I’ll throw in several other large battery banks I tore out of other projects… Lots of good batteries that I’m just not going to ever use. Someone with time should put them to good use. Make an offer and come pick them up! Text me at 808-225-6162 for pickup details.
