    Surron cutting out!!!NON-normal problem

    Do you know what the LVC (low voltage cutoff) on the controller is set to? If you have done a battery bypass(I assume you mean BMS bypass), the battery voltage could be sagging enough to trip the LVC. Use a good multi-meter to see what your battery voltage is under load.

    Fardriver 72360 beeps twice, won’t do anything after that.

    I don't have any working knowledge of Fardriver controllers, but you may have to lookup the manual and/or connect to the controller and configure the throttle and possibly other settings. Did it come with a programming cable or bluetooth dongle? Product page: ND72360 | far-driver PC software...

    Thread for new battery breakthrough PR releases

    Came across this recently, apparently you can extend the cycle life of lithium based batteries by using 100-2000Hz pulsed current for charging: https://onlinelibrary.wiley.com/doi/10.1002/aenm.202400190 Makes me wonder if you could just add a chopper circuit to your existing charger setup.

    Ninja 250 "Clone" Made in China

    Nice work! I like this kind of out-of-the-box thinking, as a note, you can use something like an angle grinder instead of a chisel, much less overall force required. I have some 20mm steel motor shafts I am going to reduce to 3/4" by spinning in place against an abrasive wheel.
