I tested this immediately with some batteries and a hub motor. Works nicely. It comes with a chinese+english manual but the english is kinda poor and confusing. Luckily the interface is simple enough.

Installed in a battery box to replace the basic LED voltage meter. Haven't tested it with a load yet but on first impression, it works well and has an easily readably screen.

Received product in less than 2 weeks. Good strong packaging. Tested voltage measurements, seems ok. Have not tested shunt resistor but looks ok. Included manual is helpful.

I like this gadget. I can monitor my battery and consumption. The only problem that it shows absolut value so sometimes i do not know whether it is negative or positive...
