  1. LVTOPSUN 4.8KWH Lithium Battery LV48100 LifePo4

    sajunky replied to Jean Vos's topic in Batteries
    Coming late, but important. These batteries have 15 cells, their operating range is maximum 52.65V. Your proposed setting is valid for a battery with 16 cells. [Side note]: trying to find firmware update for these batteries, having three different versions 1.05, 1.07 and 1.09, they don't like paired BMS controlled master/slave configuration and they don't have a physical DIP switches for setting up ID. Perhaps it is related to the firmware difference. Anyone?

  2. Battery equalizing

    sajunky replied to Elro's topic in Batteries
    Do not equalize unless maximum cell difference is higher than 50mV or experiencing unexpected shutdowns above the SOC cut-off limit. If you connect BMS to the inverter with data cable and change battery type to Lithium, all battery related settings should be updated automatically and BMS takes control over the charging.
