That depends on what betteries you have now. Otherwise a 72V 40A+ controller with 24s rc lipo will get you there for sure.
wesnewell said:Any with 100V caps and fets that you can afford. Mine cost $35 shipped and is going on 3 years now. It's a Hua Tong OT1, but out of production now I'm sure. Most any generic 72V controller should support 24s ok. if I were buying now, I'd probably get this one and have it customized fro what I wanted.

That controller only hadles 1500w max?wesnewell said:Any with 100V caps and fets that you can afford. Mine cost $35 shipped and is going on 3 years now.

yea that's what confused me.cause 100x45=4500 but it was saying 1500w, so i wasn't sure.wesnewell said:1500W is the 24/7 rating, not the max watts you can get out of it. VA=W, so 100x45=4500W
but other than that, they have the same functionalities correct? regen braking and etc...wesnewell said:Means it's rated to run 24 hours a day, 7 days a week (continuous) at up to 1500W. The difference is the model and number of fets. The one from em3 is 12 fet 4110's, the other is 15 fet 4410's. the 4110's have a better rdson time, but it make very little difference in performance. google 4410 and 4110 mosfets and you can find the data sheets for each.
All have the same basic functionality. Some may have different extra functions, such as cruise control, regen, reverse, etc. Some may have functions that aren't enabled internally, and some may not bring out wires for the functions. And some functions may actually work different on different controllers. Cruise control on some controller are activated by holding the throttle in one position for a period of time and then releasing it. Some may have a button. Some may do it by actual speed, while others may do it by power. I much prefer the button method, as the throttle method is awkward and can engage when you really don't want it to. So, if you want to know the functions of the one you buy, you'll need to ask the seller, and even then, there will probably be other functions not stated. To be sure, you'd need to get hold of the manufacturer. Good luck with that.tomtom123 said:but other than that, they have the same functionalities correct? regen braking and etc...

so the yesomusa usa kit is sensored? hmm i didn't know that, thanks. But then again, i heard that most ebike motors are sensored, very few are sensorless. I'm guess the Bafang BPM 500w is sensored too.wesnewell said:The controller I'm using will work with any motor with sensors. It is not sensorless nor would I run a sensorless motor.
evolutiongts said:Went to 15s, 63v wow what a beast compared to 48v. Top speed increased from 29-30 to 33-34mph, the greatest difference is the acceleration is just phenominal, torque has increased. Slight wheelies in going from a stop, and can hit 20mph in a only a few seconds, ramping up to 28mph quickly. Where as 48v is tame, 63v is just ridiculous. Its like going from a 250cc bike to a 500cc. 39A peak, pulling 2200-2300w.
Is is possible to show me your lipo set up ? for example, what chargers or cables are you using? How did you connect the lipos in parallel and series? How are you charging?evolutiongts said:Using the original controller that came with the kit. Yep switch to lipos yesterday, huge jump in performance.
