Product FAQ's

Yes, you can connect multiple G4 battery packs in parallel to expand your total system capacity. Parallel connections increase available kWh while maintaining the same voltage (88.8V nominal).

Do not connect G4 packs in series. This battery is already a 24S (high-voltage) pack and is not designed for further series connection. Use a qualified technician for large-scale system expansion.

On a full charge (23kWh), the G4 battery can typically support:
-Basic backup use (lights, fridge, router, fans): 24–36 hours;
-Off-grid homes (mixed appliances): 6–12 hours depending on load;
-High-demand tools (AC, water pumps, etc): 2–5 hours.
Actual runtime depends on your total power draw, and can be extended by adding solar input or additional batteries.

Yes — the Walrus G4 battery pack can be used to replace traditional lead-acid or older lithium battery banks in high-power 48V systems. It provides a nominal voltage of 88.8V and supports up to 13,320W of continuous power output, making it suitable for demanding off-grid, backup, and hybrid setups.
Just ensure your inverter and BMS can handle the voltage and current range of a 24S NMC configuration.
