600w motor/1100w E200 its gos

I have done this but now i am scared that the wiring is ok . The charging ports are they safe . Having two chargers one doing the 24v & other 12v now the Conroller duz the cel charging thing , but it's only wired up to The - to the battry & the red + is going to the switch so it's not really controlling things. Only help on this plus do I need to run a relay or a fuse on this . It's the only way Ican get a controller to run . Iv tryed 36v ones and they don't work . & the seller just tells me that it's me that plunged it in wrong . What can I do . I got a 3pin twist grip bit never got it to work . If anyone Nos how to make the 3wire red/blue/black/ & yellow if there is a way to put it to the razore200 4pin ends then let me no.

p.s you will need to remove the kickstand and the mounting bracket when fitting a bigger motor . I put a 350w 24v and it needed moving .

Plus alway make sure u go over the wiring as its best to get it right the 1st time. I will put the wiring up on how I made it go from 24v to 36v. It best I found to g mo from 24v to 36v as overvoulting with 3 battrys is gave me more room , 4 would give me no room . 48v would be cool but no room. Plus running on a 24v controller meens switching to 36v is not hard . But u run it on a 36v controller and as soon as u go to 24v it will not run as the 36v controller has a cut off at 32v .
