Good call on "Alibaba-level", I was able to find this unit on there. Not gonna link because I don't want to stir up trouble. But I'd like to set up a good system for my vehicle, and products like this make me nervous. China mass-produces a lot of good stuff but they've also got a deserved reputation for cutting corners when nobody's looking. An 18650 that's missing its overcharge circuit will happily self-ignite and take my beloved vehicle with it. Remember all those reports of hoverboards spontaneously combusting a few years back? That was eventually traced back to bargain bin Li-Ion batteries from China. Before that, there was the spate of knock-off replacement batteries for cell phones that came with a free extra crispy option. Larger companies doing business in the US fear the FTC and state governments enough to often have some form of electrical QA on anything they sell with a Chinese origin. In this case though I'd be assuming all the risk and I don't have the expertise to evaluate it for quality and safety myself.
