Battery Hookup Prototype SPIM08HP 3.7v 40ah - Shelf A2

Here is our prototype from last year when we tried to develop a 3.7v 40ah battery module using the SPIM08HP cells. Yes it worked, but it was ugly. I would personally break it down and recover the 5 cells inside. Selling for just $15. We only have two. Great for a good laugh and salvaging 5 cells.

Fully charged 4.2v
Fully Discharged 2.8v
