One GPS port broken no com possible. And the other one not able to turn on/off with switch after a few days connected to cells. Is it a bad idea? I don't know I see they sell many so perhaps just bad luck. As I want to use the battery in my RV where I'm also sleeping i prefer to have a brand...

Cool stuff! But where to buy?

Ordered 2x 4S 2A with heat and can in January. Both failed. One GPS port defect and other one couldn't be switched off. Also Bluetooth signal on one was very weak. Both refunded and now I'm on their blacklist :-0 Idea was to replace chargery BMS with JK but I'm not convinced the quality is good...

I received 2 JK BMS 2A 4S. Both from Poland warehouse. Both with issues. Got a refund for both from AliExpress after jk did not respond to any request. I'm now also on jk store blacklist. It's unbelievable that one can business like this..
