Thanks for the generous offer. Let me have a talk to the alibaba seller, she is discussing with JK what could be wrong.
I am a electrical power engineer and have done the most basic troubleshooting steps by measuring body diodes of mosfets, fuses etc.. But then again my expertise is on high voltage and high power inverter design. Electronics are not my primary area of expertise.
If you are interested i can probably ship it to you. I live in Norway so should not be too far to ship, if I take you up on the offer I will cover shipping.
Sounds like a cool project. I will have to read up it some time. Personally I much rather put my budget into more batteries or solar panels than spending like 1000 USD on a REC BMS and 3000-4000 USD on a new Victron Quattro. Therefore i am trying to make due with a JK BMS and a old used Quattro that i got cheap (1700 USD)
