Hey guys I came over the handheld console modding world and thought I'd dip my hand into tablet modding. I disassembled my m001 and removed the battery from it. I noticed that it's a 1600 mah 7.4v Li-Pol battery and after checking my personal collection of batteries I found a 3600 mah 7.4 Li-Ion external battery taken from a portal dvd player. The new battery has a limiting board. I was thinking two alternative wiring methods:1.Remove the stock battery and wire the secondary battery in. I'm not too sure if I can interchange a Li-Pol with a Li-Ion so if anyone has any input please post. 2.keep the stock battery and wire the secondary battery in parallel. With both boards having separate limiting boards, I don't see a risk of overcharging the battery but if anyone has something different to say please post.
