Powerbook 100 Battery
Posted by: Frederick on 2026-05-11 08:46:12
I'm building a battery for my newly revived PB 100. The components I have picked are two Lithium pouch cells, a BMS board and a regulator module. I have designed and 3d printed a shell in ABS. My total cost will be approximately $45. After I have the battery completed I will post photos.

LiPo/Li-ion or LiFePO4?

LiPo/Li-ion or LiFePO4?
2 flat LiPo pouch cells in series with a 2S Li-ion/LiPo BMS, then regulate or limit the output as needed.

aww, was hoping it was LiFePO4 like mine 🙁

but don't let me discourage you... that's pretty cool 😀

Looking forward to seeing how it turns out!
