Battery BMS / Controller question

[llainfactor]

Bought a 50BMS 3000W rated battery pack. 18650 LG cells. 20s 10p 72v 34aH. Its specs from factory are 50A continuous and 150A peak. The controller I have is rated 60A and motor is 3000w. Will I run into any shut off issues?

That should be OK but you could possibly overheat the BMS if you ran full power for an extended period and it has poor cooling. Usually it's hard to keep the power level at the peak for very long. Just periodically feel the parts for heat when testing. In most cases, the motor will overheat first.

What controller and motor setup. What lg cells if 10amp so 10p is 100amp draw battery ?

I think they are the 5amp model. I know there is a 10amp LG battery. I'm going to head to my self storage unit later and get a pic of the actual controller.

St. Petersburg Florida or St. Petersburg Russia ?
And it looks like it might be a no name motor. Why not get a Muxus 3,000 v3 aluminum stator 4turn or 3t about the same price.

This looks to be my motor. Same rating, two hall sensors, exact same schematic measurements given

I live in New Jersey in the United States. Yeah, so I have a Zero 11x scooter and I love it. My friend wanted an Ebike but was short on cash. We got a bike with disc brakes used for 150$ and then we got him a kit plus 17ah 52v battery from AliExpress not knowing any better. The kit turned out really well and his schwinn can do 35mph.

So I decided I wanted to make my own custom ebike with fat tires and did pretty much the same thing. Right now the wheels are set in motion I'm just trying to find out if I'm able to mitigate any issues. I think the sw900 display will let me limit the controller amperage to that of my BMS.

Sorry for not answering sooner.

I love it. Just wanted something that doesn't make me have to stand the entire time and is a little less conspicuous.

I looked up your battery cell and saw that it had LG cells LGGEF 3,400 mAh ? Couldn't find it ? I would like to know how this battery works out for you.
