The battery builders club

Took apart a Chi battery CBSP 15S1P 30A pack for onewheel +XR.




I like the strip design. The extra relief cuts look like they will help decrease contract resistance.


Typical hot glue bonding. Once I started pulling off the fiber tape it did not hold together because of the unique layout.

Four RTD’s. They each have a piece of silcone pad, I guess to improve contact. I just use thermal paste.

Pull test. Looks good.

Looks pretty good electrically. Could use more structure. It’s really just held together with fiber tape.
