Hi all, do any of you have any ideas on the best way to discharge test a 3.7v nominal 18650 pack? i use it as a solar powered power bank so at the moment i'm just using it to charge stuff through a USB current logger, but of course its going to take forever since at the bare minimum there'll be...
Got a whole ton of 18650's sitting around, many rewrapped, got a couple UR18650As and ICR18650-22Es along with a couple LGES318650, going for around ~£2 per cell, let me know if yall wanna buy any, UK only cause shipping is dumb
Damn, wish i saw this yesterday cause i just threw out a lot of dead cells... local council does recycling for em, ill let you know when i get some more duds, my luck with recycling cells has been pretty good recently!
Hey all, so since i'm sick of having my RPis corrupt after a couple sudden poweroffs here and there and after a power outage yesterday that entirely killed one of my SD cards, i decided to make a very low effort UPS for my main one. I use this one as a server for Pihole and also as a web server...
Hi all, fairly new around here, i have a 6v solar system set up with just a couple 6v1w panels (6 to be exact) to charge a bank of 18650s, does anyone have any recommendations for high efficiency and fairly low cost solar panels?
Yeah, i mainly get my cells from old laptop packs and i've had a couple VERY rusted ones come my way, just toss and move on cause i don't feel like
a) getting tetanus
b) burning my house down with a rusted battery
