Razor MX650 15kw+ RV 120 Pro

I have basically everything ordered. Motor being ordered very soon. Batteries are only temporary I'm probably going to have to use some hybrid batteries because I'm not trying to spend $2000 on batteries that f me over on this super awesome project I don't want anything to go wrong. But I'm still deciding on speed controller. I am easily running up to 60v right now with 4s4p bundles of 2 together. The batteries are 60C Turnigy Heavy Duty XT90 4S 5ah They really pack a punch. I have 4 the other 4 coming tomorrow for 10ah 60v. If anyone knows any used budget friendly 18650 or 27770 packs for sale please DM I might might might buy. Haha I'm desperate to get this thing running it's gonna be awesome. I think I'm gonna go belt drive but I don't really know much about different belts so I have some stuff to figure out still. :lol:

It would interesting if I found a good 100+v controller with high amps budget friendly and hooked up some separate 6s2p to get 100v+ short burst like a turbo that would be badass.

Don't order the revolt motor for an ebike project. Only bad results found on this forum with them.

Any updates!? There are some 100amp brushless kelly controllers of a skateboard in the sale section that might work for you. Have you looked at doing hub motors at all?
