Vevor 1000w hub motor

[RebelPrinter]

I am looking at the Vevor 1,000w front hub 48v kit, but already have a 52v battery on hand. I tried contacting them and got the standard "48v, no more, no less" CYA response. Has anybody tried 52v on one ? Or do I need a buck converter to step the 52 down to 48 ?

Most 48v controllers will work on 52v, but you don’t know for sure without looking at the rating of its components (usually looking at the capacitors voltage ratings is an indicator).

Make sure you buy either one, but preferably two good quality torque arms for a front mounted 1000w hub motor, and throw out the crappy one from the kit. Also, not sure what your plans are, but it’s generally not advised to use a front hub of that size on a suspension fork.

A buck convertor would kill your efficiency/range, you don't want to go that route.

Basically zero of these super cheap brands know anything about what they're selling. Most companies are just resellers.
The included controller is probably not programmable and probably not good. Maybe you want to try 52v, with a backup plan of using another controller if something goes pop.

A shot of the internals that shows the MOSFET model numbers and capacitor max voltage could help us tell you if the controller could handle 52v. Most MOSFETS and capacitors are rated for 63v, and 14S batteries charge up to 58.8v, so it's usually the case that a 48v controller can handle 52v, the variable you don't know about is if the manufacturer locked you out of that capability or not.

ifyou're looking for a cheap kit, you might be better off with one of the XCSERIES kits; they've been doing this a long time, and they even include a spoke nipple tightening tool for when the wheel starts falling apart from the too-thick spokes they all use.
