Is the shunt mod just increasing the amperage through the controller? If so, is it an arbitrary increase in amperage or is there a way to determine or control the amperage when doing the modification?ĭoes this mean that with my 900W motor and 36V batteries I only need 25 amps through the controller to run the motor at max? If I mod my controller or get a new one it will increase my acceleration and hill climbing, but will decrease my range. If the 36v battery setup is 20ah it will increase my range. So if I go to 36v battery setup it will increase my speed. Modding or getting a new controller for acceleration and hill climbing will decrease overall range. Going to 36V (adding a battery in series) would increase top speed and keep range about the same.Īdding another battery in parallel would keep top speed the same and increase range. will reduce your overall range as it is pulling Amps faster from the batteries.īest I could say is the add batteries and mod the controller.

and search for "shunt" mod on these forums to see how to increase its performance.įor a longer range, you are going to have to add or replace your current batteries with higher ah ones.Īlso, increasing the performance on hills etc. Maybe you should open it up and look at it. either by getting a new controller or modifying your stock one. If you were to wire them in parallel you would effectively have a 12V 24ah battery.įor better performance you need to get the motor more Amps.

In series (which they currently are) it is like 1 24V 12ah battery. Not sure how much you know about batteries, say u have 2x 12V 12ah batteries (as you do). a 20ah battery will take you almost twice as far as a 12ah battery. the 12ah of the battery is basically how long the battery will take to discharge at 1 amp per hour.
The more Amperage the motor gets the more torque it will produce. The more Voltage you use the faster the EV will go.
This is what also limits its power up hills and acceleration.Ģa. yes your controller limits the Current to your motor. In my experience with EVs, a 12v step up is usually ok, so going to 36V should be ok.Ģ. Its impossible to know for sure how much voltage your controller and motor will take. I am not an expert but here is what I know.ġ. What do you think is the most cost effective way to improve hill climbing and range?Ĥ.Any recommendations or advice from more experienced and knowledgable people is welcome.

Does this mean my controller is limiting my motor and that just replacing the controller could improve performance?Ģa.What effect does using battery packs and/or controllers with higher or lower Amperage ratings have?ģ.I don't want to spend more than a few hundred dollars to upgrade this scooter. Here are my questions:ġ.36v should be relatively harmless, do you think 48v would be overkill and burn out the motor? (this is assuming that I use an appropriate controller)Ģ.I saw the formula W=V*A and when I plugged in my 900W motor with the 24V battery pack I came up with 37.5A. The motor does not even get warm after dragging my 200Lbs up hill until the batteries are drained so I am thinking about overvolting. I plan to use it for my daily commute to work which is a daily total of ~6 miles. I live in the Sierra mountains and there are few flat areas so I need to improve the hill climbing ability and range of this scooter. I doubt I am getting more than a couple of miles before the scooter is barely crawling up the hills. The battery life seems to be really short too. The scooter seems to have decent power on the flats and slight grades, but seems to lose speed rapidly on some of the steeper grades around town. This scooter has a chain drive, but I don't think it freewheels.(lots of motor whine when coasting downhill with the throttle off). It has 24v 12ah battery pack and a 24v 30A Motor Controller. They were only $170.00 each brand new in the box! The motor says it is 900W. I just bought two Currie E-Zip 900 scooters from Sam's Club.
