Looking for some assistance with batteries discharging at different rates.  I have a SolArk 15-LV and two eVault 360ah batteries and the batteries are discharging at different rates.

    Please explain further. Are these in use on the same system? Are they on different charge controllers? How are they wired if on the same system?

    When I changed over to LFP04 batteries the installation requirements made it quite clear that a connecting bus was preferred but if individually wired that each block have EXACTLY the same cabling AND length regardless of position.

    Also bad balance from the BMS of each battery not being networked as a system. Defective battery is up there also.

    Set-points? It seems there are so many ways to mess this up. Why do we do it😉
