So are they still selling packs?

Tried that a while back and nothing charged but the direction. Power going backwards still felt better. Really annoyed with setting up this Kelly controller. Had it relearn my Motenergy motor without issue but these cheap my1020 motors won't act right (I've tried two so far).

It appears so but that doesn't make any sense. That's why I want to try the motor with my Kelly controller.

So is anyone this motor with a kelly controller? I'm trying to set my up via the auto identity and that appears to cycle just fine. But when I try to bench run the motor I get high speed stutters with the rpms shooting all over the place. Funny thing is it worked fine when I first hooked it up...

Thanks. I figured it was related to weight shift (forward CW, reverse is CCW) with my kart. Reverse burns rubber and speed offs strong while forward is far less exciting.

This may be a dumb question but do these motors run better in one direction versus the other? This is motor only, ignoring controller settings. Thanks

Thank you, that was very helpful. It's nice they have those kind of simulations for slopes.

According to Google is looks like a 5-7% gradient in certain places. I have one of these for the towing.

So the moral of the story is I will have to pedal with a hub motor but will be a lot easier than without one.

Correct, same logic with RC brushless motors. Look for the lowest KV motor that hits the top speed I want at a given voltage.

Huh, I always thought watts were watts with the only difference being high voltage means less amps with less heat and resistance.

After building several electric gokarts ranging from 350w to 13kw I'm now looking into building an ebike. My fast kart weighs 200lbs, I can't ride any of my karts outside of my subdivision, and I'd like something that I can go out further and tow my daughter behind me. I'm looking at rear hub...

Do not get a cellmeter 8. I bought two from progressive RC and both are way off for individual cells. One is 0.04v at it's worst and the other is 0.06v.

There is nothing you can do. You can't wait that long to file a claim. I also believe I bought bad batteries from Tech Direct. I bought their 20ah Panasonic Lithium batteries. One has completely failed and the others don't even reach 20ah. I bought 5 more from used cells greentecauto and they...
