12S 10000mAh Lipo for 1680w motor?

[andrenoites]

Could a 12s 10000mAh c20 lipo be enough for a 1680w cyclone mid drive motor?

My controller cutoff with over current error above +/-26 amp, could this be the battery related?

No,..its your controller that doesnt like the high current draw that the motor demands.

If your controller is cutting off because of overcurrent, it's likely trying to tell you to stop riding in too high a gear. Shift down, get the motor rpm back up, and the motor won't pull such huge spikes of current.

1680w from a 48v pack requires 35A min. The typical controller is 100A. Which controller do you have? Does it need reprogrammed?
3.5C(10C) is no problem for lipos. Wattmeter numbers and more detail on your setup could help figure out the cause.

The controller is a Kelly KBS48101 with 35A continuous and 100A peak (10 seconds)

Currently I'm using max motor current at 50% (50A) and battery max current at 70% (35A)
The watt meter records current peak at 26Amps and max voltage sag is 0,1V at peak (measured in battery side)

dogman has is point, at high rpm I never have a cutoff also because at high rpm max current draw is about 18Amp (seems that's because the motor is more efficient at high rpm)

I still have to tweak the drive gears to give a better pedaling cadence combined with high rpm.

Even so, I'm curious If wasn't supposed go get better torque with slightly high amps at low/mid rpm, even that was only for a 10 seconds (controller max current is 100A peak).

Tks in advance,
André

If your wattmeter is recording 26A max, but your controller is set to a 50A cut off, then something is wrong with your controller setting.
Also, I dont know the cyclone motor you are using, but if its "rated" at 1680 W then it will be capable of pulling much more than 35A.... for short periods.
check your watt meter settings /connections also to be sure you are getting the correct data.

I like to thank all for the help

Changing the throttle setting from pod to Hall fixed the problem

I 'm very happy with the result, now the bike is super easy to ride and powerful

Tks,
André
