This is one of those “fun” problems I've been itching to tackle for ages: the very first JK Inverter-BMS I installed in a Gobelpower SR1 battery decided it had trust issues and refused to talk to other BMS units—or even the PC software, for that matter. The Bluetooth app? Oh, that was feeling chatty and worked just fine, letting me access the BMS and tweak the settings. The CAN communication to the Victron Verbo GX? Smooth as butter. But RS485 comms? Dead as a doornail.
So, the obvious plan was to swap out the comms board and cables because, you know, why not play hardware roulette? If that failed—and let's be honest, the odds weren't great—I’d have to bite the bullet and contact Jikong for advice. After all, this was the very first JK BMS we ever tested on the channel, so maybe it was just having a mid-life crisis.
Cue the ‘crane-action’ (don’t ask) and a fun session of battery Tetris in the Gopelpower stack. With everything in position, I rolled up my sleeves and dove into troubleshooting, only to be greeted by a plot twist I did NOT see coming…
