@NormanDunbar @bornach I've got some of the cheap 4056 charger module variants which have over discharge protection built in. I'm going to track down those usb dc boost modules though, they look very handy.

@concretedog @NormanDunbar
I have 10pcs of those modules too. Problem is I now have over 60 unprotected batteries and I keep finding more. Might have to parallel them up or make my own BMS

Homemade BMS - Balanced LiPo Charger Multiple Cells and Current Limit

YouTube
@bornach @NormanDunbar I'm probably over 30! The lure of multicell and BMS is strong. Although I also have balance charger so could also go down that route for multi cell approach. I'd have to get them pretty balanced first thought which could be a challenge!
