I’ve just finished my DIY build and I forgot to buy a charger for my 10s3p battery. I friend has a charger from a wowgo 2s that I can borrow, think it is safe because they also use 10s systems? Can someone please confirm, I have attached an image.
Also, probably a stupid question but do I need to have my loop key plugged in so the board is ‘on’ when charging? Or is it ok to charge without the loop key in?
