Thank you that was the idea, In the missing tutorial I explain that I used batteries from a power bank with a broken usb. So yeah re-using stuff, this tablet should last 10 more years at least! https://www.circusscientist.com/upgrade-your-tablet-with-replaceable-batteries/
Geez did I not link to the tutorial here? That’s what happens when you’re in a hurry. https://www.circusscientist.com/upgrade-your-tablet-with-replaceable-batteries/
Also, no I don’t take it out of the house - and the batteries are from an old power bank so essentially free.
Actually capacity exceeds the original spec. Battery indicator seems accurate though.
