I need a few BAD X-star batteries to rebuild

[DrDadio]

I am looking for a few BAD x-star batteries to test a rebuild method. I was able to recover a battery by harvesting a good cell from another bad battery and then fake out the BMS eprom. Now I want to see if my hack for the BMS board will work using an off the shelf lipo, but I need a few more batteries to play with.

I have 4 - 3 are puffed pretty well, one is bulging slightly.

Let me know here or [email protected]

Nope, unless you know how to reprogram the BMS you are out of luck. You need a battery fuel gage chip and software. Even with this I still need to write code. I probably am way ahead of everyone but the SMBUS connector might allow other batterys to communicate outside the original pack. But now we are getting into reprogramming the MB....

Looking over the old threads....wondering if you had luck with the programming?

Aside from just adding a newer battery to an old BMS, no. And no matter what, you are limited to about 16 mins flight regardless if you are lucky.
