For me is this a nice produkt , and it works good!
Arrived very quickly and easy to connect up. Am using it to monitor home battery daily charging characteristics. Works brilliantly and the cumulative kWh display is very handy for keeping track of total battery throughput.
Using it in series, between charger and 48V eBike battery. Exactly what i needed for monitoring charge cycle
Well packaged. I have not tested it yet
