Yes, converting 24V to 48V is achievable through series wiring of two 24V batteries, DC-DC boost converters, or motor/controller rewiring. However, success depends on component compatibility—battery BMS, inverter limits, and wire gauges must handle doubled voltage.
[pdf] Short answer: A 48V battery typically requires 13–16 lithium-ion cells in series, depending on cell chemistry. Lithium iron phosphate (LiFePO4) cells need 15–16 cells (3.2V each), while standard Li-ion cells require 13–14 cells (3.6–3.7V each).
[pdf] To safely charge and revive 48V lithium batteries, you must follow precise protocols, monitor the state of charge, and avoid common mistakes. Use a compatible charger, work in a ventilated area, apply low-current charging when reviving, and utilize advanced management systems like BMS.
