i was successful installing the kelly KBS48101L on my bike for a test ride. had some issues as it was always cutting out very early at half throttle and i didn't know why the last time i tried it, so i though: what a piece of junk and set it aside. today, as i was wondering what all those additional wires coming from the controller where good for, and all ppl talking about diagnostics leds i read the manual.
now i know that my controller has leds as well - you just need to connect them - i thought the "better" controllers have them built into the case.
so with the leds installed my controller tolds me that a) my throttle was not connected and b) that my hall sensors where faulty/not connected. which both was correct, as the controller was only setup here on the desk and not installed to the bike
so after programming it (all values maxed out) i was looking for the correct hall/phase combination. i found one but the bike was always cutting off power at half throttle. so i connected a turnigy wattmeter in line to see that no load current raised where quickly and jumped to 15a and then the controller shut off with blinking leds 4-2 (hall problem). so i tried some other combinations until i found the correct one. 3a no load speed (with the motor driving all gears and rear wheel). nice.
went for a short test ride, and now i know why ppl like them so much. a very smooth nice ride. very different from the infineon type one. especially with a mid drive and some drive train lag a current controlled torque throttle is MUCH MUCH nicer. there is no brutal kicking in like with my other controller. and it seems to be more quiet as well.
i will now have to find out how to set battery/motor current percentage correctly to achieve my wanted 45a/80a as i had it with the infineon. and then i will see if i can install the kelly internals into my 12fet infineon case so i can screw that to my bike.
wish me luck
too bad it's f**** cold outside. doing a quick high speed test ride at 60km/h with only a polo shirt and a vest is COOOOOLLLD!!!
