Did try to fit the 800w motor but would need to reline the holes drill them . Not much work I no but when u work out that 800w 36v max when 600w24v to 36 = 1100w it makes sense to g for powe . Plus the two motors just fit like they was ment to be lol .

it's was going to be a 800w 36v scooter. I cut the floor plate as the motor needed to be mounted on top. But it's a lot of work and not a lot of room to do a 36v big motor. So I got a 350w 24v& a 250w 24v & put them on top each other . So 600w 24v. But I have it done on a switch so it's on 24v & when I want to I can make it 36v. 600w overvoulting to 36v makes it a 1100w motor nice . If I had of put the 800w 36v motor to it I would not of got to the power the two motor put out . So even if I do over heat the motors I can alway go back to the 800w 36v motor & run it on 24v controller & it will be a 600w on 24v . Flick the switch and it's 800w on 36v. U mite say why not just get a 36v 800w controller , lol I did 4 of them. I blown the 1st one up , the other two I put the wires all right but switched the power on & the motor went hard on , so it went wide open. The other controller I got told by lot of others that I must be putting a wire on wrong. Lol .

So one more I did it all right making sure 3/4 times befor putting the ends together . I no I did it right but as soon as I put the blue & red to the on & off switch & power leads on the motor went hard on again . So I gave up. Now the razer e200/300 controller is for 24v but unlike most 24v controllers they have put a cut off Over V metter in there and u put 36v to it and it will not start . But if u run it on 24v then use a SPDT switch a (on off on) then as u r moving on 24v wether it's a 800w motor or a 350w motor. U flick the switch and it lets u go to 36v . When I 1st overvoulted my 350w 24v to 36 v I could not believe the power to it . So that's my way around the controller on the razer e200 controller . I seen that u can put a wire across a part in the Conroller but Iit don't let u put 36v from the start . Sham

If anyone Nos how to hack the controller with out blowing it up please let me no . I seen TKs one wear he put a wire from the metal strip to the ground . If u no that work then let me no . But TKs put new moss fets inside & so on I no that's to much for me to do .

Anyway i did a cover for it at 1st it was to cover the 800w motor , then it was to put the other battey inside . Now it's to cover the two motor . It's been fun and it was a 11 mph scooter when I got it . At it top I was getting 18/20 mph . I did get it to go to 28/30 but it was way to fast and with 8" wheels u got speed wobbles . & my 13 year old son has been helping me convert it & so on . But it's cool .

I do wish I got a razor E300 with 10" wheels as it gos 14mph standard with just doing the sprocket & going to say a 500w motor u will be doing 20mph.next scooter will be E300 put a 500w motor but 24v overvolting it to 36v then sprocket 12 teeth front 44back . Then maybe put a 500w or the same motor that's on the bottom & mount it on top like the last one I did . But two 500/800w motors on 24v overvolting to 36v that a lot of power plus the gearing wow u be dining 35/40 mph & 10" wheels well I no what I am doing next .
