Important Note For Victron-Based Systems: 

Pylontech US2000, US3000 and US5000 batteries use 15 cells in series, while most other LiFePO₄ batteries use 16 cells. When a Victron system charges to 53.2V, a 16-cell battery spreads that voltage across 16 cells (about 3.32V per cell). A 15-cell battery has to spread the same total voltage across only 15 cells, which means each cell sits higher voltage (about 3.55V per cell). Because the cells are operating closer to their upper limit, some systems may show a high voltage warning during the final stage of charging. Lowering the maximum charge voltage slightly (for example, to 52.4V) reduces the voltage on each cell and can help prevent these warnings, with little change to usable capacity
