A part of the review has been auto-translated.
Very good at what it does, but it is not capable of sensing which way current is flowing. All current flow adds to the Capacity reading so state of charge can only be read from the SOC bars which are a function of voltage so they are no use for LiFePO4 batteries.
Product complete. Delivery fast.
Ótimo produto para controlar consumo de eletrônicos nas baterias
Thank you very much received.
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.
Working very well
very good product
Exactly as it is in the descriptive, very good, would recommend.
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.
