Full Charge Voltage of a 48V Battery. The full charge voltage of a 48V battery depends on the type of battery: Lead-Acid Batteries: Fully charged lead-acid batteries typically reach a voltage of 54.4 to 55.2 volts. This figure can vary slightly based on the specific battery type (e.g., flooded, AGM, or gel) and the charging system used.
I don''t think full depth discharges are needed. The unit can only balance at 100mA, so it''s more a function of time at voltage during charge. A slower charge would be more advantageous than cycling. if you had a power supply that you could hold at a given voltage and charge at 0.1A, that would allow the battery to balance at a constant.

Finish the charge with a lower float voltage around 2.25V to 2.30V per cell. This maintains the full charge and compensates for self-discharge. For wet cell batteries, carefully monitor the voltage at the end of charging. Stop charging if the voltage remains at 2.4V per cell for an extended period to prevent overcharging.
Please be aware that as the battery is charging up, it slows as it starts to reach full. A 12V/200AH Battery has an EndAmps / Tailcurrent of 10A.
