Hello, I'm new to the site and electric vehicles, I just recently bought a daymak Hamilton electric scooter because y 50cc 2 stroke scooter kept breaking down on me. So far I'm really liking the e scoot, but the speed sis a little lacking, even though it's a 60v system. I'm guessing that the contributing factor would be the controller. The range of the scooter is great, I took it for a good long 50km ride and the battery only went down to 24%. It is running 5 12v 20ah sla batteries. Now since I can't afford to get the lifepo4 batteries and the charging system, I was wondering if a better controller or if I added another battery to make it 72v if that would help increase the speed. As I said I'm new to EV's

Ive been doing alot of reading about ebikes and their parts, like the controller, motor and batteries. i also found out that my controller is rated at 60V 500W 15A. now would a 60/72V 1000W 30A controller help give me that extra bit of speed that i am looking for? maybe even enough to get me up to 50km/h quick enough to keep up with traffic?
Also here is a picture of what my bike looks like. same color and style.

open the controller and show what the input caps and the mosfets look like. your controller may work at 72V now but until we can see the parts, no way to know.
I took off the end of the controller and checked the caps, and they are rated for 76v. I can't rememberw hat the uf is. Also while I had the end off I took the liberty of adding more solder to the shunt bars. I've seen this trick on YouTube and people said it helps, and it does. Hard to imagine what a little extra solder could do, but I did feel a little bit more take off power them before, not much but a little. So once I get y next pay I'll be getting another 12v 20ah battery and wire it into the system. They are pretty cheap at y auto parts dealer at $50.

no pictures. no info. i have never heard of a 76V capacitor. uF is microfarad.
didnt have my camera handy while i was working on it. i think it was 76v, may have been 72v, it was hard to see into the controller but i know there was a 7 on the capacitors. and im not about to take it apart again until i have too, as the controller was a pain in the read to get out.dnmun said:
Hi - after a few comments I decided to install my new mr scooterboost battery but keep my Daymak Hamilton controller. I couldn't figure out how to hook up the replacement controller from scooterboost in any case. Now, with 72V I get a few extra clicks and much better hill climbing. The truth is that if you increase the speed a lot it is no longer an Ebike - you need insurance, registration and licence. I'm happy with what I've got. Tom
