Sunsynk 8kw and 2 x 6.4 BSL battery problem
Hi, I have a sunsynk 8kw inverter with 2 x 6.4kw BSL batteries connected. The problem I hae is that the master battery run down to 20% while the slave battery is sitting on 80%. BSL advised the settings for the inverter is not correct.

Hi Desmond
I can tell you from experience that the LED lights are not always accurate. I have one customer who bought three Coslight 48V 100ah lithium batteries and I installed them for him. He has the same problem with the LED’s being different all the time. The one battery has 5 LED’s permanently while the other two will go down to 1 or 2. When checking the voltage of the “pack” it is accurate and the individual batteries are all at the exact same voltage after many months of cycling together.
He has just decided to ignore the other two batteries and focus on the one that gives the most accurate SOC.
I’m not saying this what is happening in your case, but I have seen this happen before.
