Hi there. Me and my girlfriend are traveling in a self converted van and we’re using your BLUETTI AC300 with 2 B300 units.
The B300 batteries are connected in parallel to the AC300, and everything is running on the latest firmware update. However, one of the batteries refuses to properly connect. It shows up on the screen but cannot provide power to my van. Only the other battery discharges when I’m using power, while the problematic battery stays at the same percentage.
Although it appears to be connected, there’s no green “on line” indicator in the settings of the AC300 for the faulty battery. The working battery does have this green light. Additionally, in the BLUETTI app, the problematic battery doesn’t display the “parallel” symbol, whereas the working battery does.
Occasionally, I get a brief error message saying that the cables are not communicating properly. When I restart the BLUETTI, the green light and the parallel symbol for the faulty battery appear briefly (just like on the working battery), but they disappear again after a few seconds.
If I only connect the faulty battery with the AC300 it does work propperly for this amout of seconds, and then it dies. (Not the battery, the AC300).
The battery starts to flicker (also 7 times).
Do you have any idea what could be causing this issue?
The SN nr of the AC300 is 2217000470732.
Please feel free to push an update through whenever you want.
You would be a life saver is you could solve this problem for us. Thank you in advance!
