What will changing from a 48V 20 amp controller to a 48V 30-35 amp do for performance on a E-bike hub motor?
I am having a lot of fun with my EV Tech BMC brushless hub motor, but as usual with me, I am now looking to increase the power a bit. I am running the Crystalite 48V 20 amp controller, and wondered if I went to a larger amp controller what affect it would have. Would the hill climbing and acceleration be affected? Would it change the top end on flat ground?
I am currently running a Ping 48V15ah LiFepo4 Battery with a 2C continuous 3C peak BMS set up. I don't know if the 40amp Crystalite Phoenix controller would over work my battery, or if it is compatible with the EV tech geared hub motor. Anybody know? Also, anyone know of a brushless e-bike controller that is a 30 amp rating?
Let the specs for the ping battery be your guide. Unless someone out there is running the same motor and controller with the same battery. A cycleanalyst would really help you to know what you are realy using in amps when actualy riding. Hills and the speed you ride can make huge differences in real world draw on the battery. On the other hand, you could resell the new controller pretty easy for less than you paid for it if it doesn't work out for you. I'd be inclined to just try it, and maybe get more battery later if it doesn't work with the bms you have. There is talk that ping is getting new bms in the future that can be parallel connected. With the new bms, you could get another battery to provide the amps you need. Imagine the range you would have then!
With lith batts with bms set to protect the batt look for " continuous discharge XX Amps and do not exceed that . the controlers can over amp with a simple jumper . if you just want to go faster you have to raise the voltage LaTer
