Battery lithium 36v 10AH36V, 10Ah is running for 9 hours with no load on the motor (with 0.5A5 A draining) which gives us 4.5Ah5 Ah, and for 2 minutes with load on motor (witch 17Awith 17 A draining). ifIf we consider 4.5Ah5 Ah and not 10Ah10 Ah, it should stay working 16 minutes. I changed the BMS and still have the same problem, I checked all the wires connection. What could be the problem?
