The 24V 300Ah LiFePO₄ battery is the energy core designed for high‑consumption RVs, converted buses and off‑grid homes. With 7.2kWh of total energy, it can power a 2000W induction cooktop for 1 hour, a 1200W RV air conditioner for 5‑6 hours, plus auxiliary devices like fridge, lights and water pump all day long. Using Grade A LiFePO₄ cells and an active balancing BMS, each cell string is kept in optimal condition, greatly extending cycle life and safety margins.
| Scenario | Description |
|---|---|
| Large RVs / Bus Conversions | Powers high‑draw appliances: induction cooktop, microwave, roof AC, water heater, washer/dryer |
| Off‑grid Cabins | 7.2kWh per unit – 6 units in parallel provide up to 43.2kWh for week‑long autonomy with solar |
| Home Backup (Critical loads) | Keeps fridge, freezer, medical devices, sump pump running during outages |
| Boat / Marine (48V hybrid) | Two units in series (with proper BMS) for 48V systems in electric yachts |
| Workshop / Mobile Office | Silent power for tools, computers, communication equipment |
Q: Can it directly replace the original lead-acid battery?
A: Yes, 12.8V is compatible with 12V systems, with adaptive size and consistent positive and negative poles, plug and play; it is recommended to check if the charger supports LiFePO4 (14.4V-14.6V).
Q: Does it support parallel expansion with multiple batteries?
A: Yes, it can be paralleled with up to 4 batteries, with a total capacity of 1600Ah, meeting the demand for large loads.
Q: Can it be used in low temperatures in winter?
A: The standard version can be charged above 0℃; the optional low-temperature heating version can be normally charged and discharged at -20℃, suitable for RVs in northern winter.
Q: How long is the service life and warranty period?
A: 3000+ cycles (70% DOD), usable for 8-10 years under normal use; 5-year warranty (free of charge for non-human damage).
Q: Is maintenance required?
A: Zero maintenance, no need for water replenishment, balancing or regular charging, low self-discharge rate, and slow power loss during long-term storage.
Q: Is it safe? Will it explode?
A: It adopts LiFePO4 (lithium iron phosphate), which has stable chemical properties, non-flammable and non-explosive; built-in BMS multiple protection and flame-retardant shell, safe and reliable for RV use.
