@lemur yes, I'm familiar with the CHI battery. nearly bought it. and then realized that... I can do better! maybe... hopefully. could blow my feet off. one way to find out.

I suppose OW is concerned about liability for people opening up their boards and repairing themselves, but interestingly enough, I believe California just passed a bill for "right to repair" their own cars. Which means parts and specialized tools must be made available from the OEMs to the public. Hopefully consumer electronics will follow suit. I need to fix my OW, and a drone I crashed, and again, neither will sell me individual parts for me to repair it. Funny thing is that I'm a professional engineer who designs and builds electric vehicles.

Because the BMS on my OW+ is cooked and OW won't sell me a new one, I'm designing a building my own battery with new BMS, capable of quadruple the range of the original OW+ range. 550 Wh versus the stock 130 Wh. I'll let you guys know how it goes.

If anyone has swapped over to the CHI CB+ battery for their Plus, they should have the stock BMS board laying around. Might I purchase this from you? Mine has been water damaged and OneWheel will not sell me another.

thanks,
Sim
