Hey I have my old outdated tablet and its battery died ( 2.2v somehow ) and when I opened it up ( it was open for 2 months prob ) and then tryed 2 18650 cells in parralel ( plus with plus and neg with neg ) they where 3.8 v it didnt work! Then tryed a normal battery (3.8 v but 1800mah ) nothing happened
I think I fried my tablet cause to reverse polarity.
Tablet chipset Alwinner a13 ( worse than banana pi ) and the 18650 cells are 2200mah each so I gave it a 4400mah battery first ( but dosent matter because 3.8 v )
