You know right your max ampere usage must be below 15A or the BMS will get cooked. And that means your batteries are kinda overkill/useless because they have such high discharge rate.
Everything is perfect expect for the BMS, the bms only tolerate up to 15A, and your motor 80A. So you will not get the max power with that bms because the max is 15a and it will fry. If you bypass it like @makevoid said, only use it for charging. Then everything should work just fine
Like what I posted earlier. I’m just afraid that the batt will be killed rapidly? (something about rapid discharge destroying batteries?) without the bms.
I suggest to search for somebody who knows electric circuits before/while connecting everything together to prevent you creating a short circuit. With any battery but with lipos more than others you risk to make the battery damage itself because of a short circuit.The multimeter lets you test that the current is flowing in the direction you want (checking voltage), and if you turn the knob to the Ω part of the “pie” you will be able to check resistance (for example if a end of a wire is connected to the right end, to see if a material is conductive etc). So either learn some basic things about circuits or get a help from somebody that knows and if you can get a multimeter, get it. ^^
Excellent battery choice!
And don’t let anyone tell you these batteries are overkill. They are not.
Even with these batteries, there will be a little voltage sag.
But much less sag than lower power batteries.
