Hello all,
Someone gave me a Trek bike with a Bionx motor and battery (Model 7200+).
The battery has been sitting for years and it's dead. Won't charge, even after replacing the fuse that had been blown inside the battery. Voltage is zero. Charger seems to be functional.
I tried to ride the bike without a battery. The motor is "resisting", which makes me think that something's shorted inside, most likely the power MosFETs. I assume that the MosFETs blew the fuse. Yay.
At this point I'm considering buying new 18650 elements to rebuild the battery, AND dismantling the motor to fix the control board.
Is it fair to assume that's everything that's broken/defective?
Can anyone think of a better alternative that won't cost a lot more?
I also considered buying a different battery, gutting the motor and using a non-Bionx controller. Is that a reasonable alternative? Or is it too much work and way more expensive?
Thanks in advance for any answers!
