I don't think it'll overheat because it's quite a low speed wind. It feels a lot slower and more efficient than the Xiongda in high gear, but I don't think it will match the Xiongda in low gear, which is like a winch; however, the Q128 has an ace up its sleeve. The Xiongda is probably close to its limit at 48v 15A, while as the Q128 can go up to 28 amps at 37v according to that test report, so 23 amps at 48v should be OK, which will give it immense absolute climbing power. I don't have a 48v battery that can go that high on current at the moment to test that.
