DIYBMS v4.2 controller boards to sell

I have to 3 empty DIYBMS 4.2 controller PCBs and 1 partly assembled (carrying the hard to get ICs, only missing relays, pin headers and connectors) that I’m happy to sell as I don’t want to throw them to electronic waste.

I’m located in Germany but can ship in Europe as long as you pay the shipment costs and like to see 20 € for all 4 PCBs as on the picture (I can also add the JCT connector for free if you don’t have them).
