Hi everyone,
I have a Blue Smart IP22 12/15/3 (HQ2204) charger in my boat. It’s connected to two EFB batteries. It has started acting weird, the LEDs are not lighting up and it won’t connect to my phone when connected to my batteries. I have tried both batteries separately, same issue.
When I disconnect the batteries, it will connect to my phone and the state + mode LEDs are blinking. At first ABS and Normal are blinking, when I change mode to Recondition/High it will change state to BULK (still blinking) and then switch back to ABS (still blinking). Without any batteries connected, the app says the output is ~5V 0A.
I have tried resetting and updating the firmware. I have checked the fuses but it’s fine.
For some reason I tried switching it from Charger → Powersupply and I had to reset the charger with PUK for it to reconnect and then it jumped back to charger mode.
During the winter, I have charged both batteries with another charger, so they are both healthy and working.
Any help would be greatly appreciated!
