I thought you said in the other thread that you damaged something without upgrading the battery. You need to find out why first, otherwise your new battery might just do the same quicker.
Hi, l don't know what going on. I took out the battery, cleaned the peddle assist magnets, put it all back, turned on the battery and everything lit up and was working as if nothing was wrong with it. It's a mystery. When l get home in a hour l will make sure all cables are OK, and tomorrow l will try riding it, finger's Xed. The battery upgrade is for my second bike, and has the same specs.
In principle, you can run any motor at 52v. The higher voltage makes the motor spin faster. You should design your system such that the motor's maximum speed is about 1.3 times your modal riding speed. That's to keep the motor running in its efficient zone so that it doesn't overheat. the motor would also need enough power to run at 3/4 of its max speed to run efficiently.
