Product Overview
The 48V 100Ah LiFePO₄ battery is a high‑performance power source designed specifically for RVs, campervans and off‑grid systems. Using LiFePO₄ cells, it is approximately 50% lighter than traditional lead‑acid batteries and offers 5‑10 times longer cycle life. The integrated 100A smart BMS provides comprehensive protection to ensure safety and stability during your travels. With 5.12kWh of energy, this battery can run an RV air conditioner for 4‑6 hours (depending on AC power consumption) or power a fridge, lighting, water pump and other appliances for a full day.
Why choose a 48V system over 12V?
Higher system efficiency – At the same power level, current in a 48V system is only 1/4 of that in a 12V system, reducing cable losses
Lighter overall weight – Thinner cables can be used, making the entire wiring harness lighter
Better scalability – 48V is a standard voltage for many modern RVs and solar inverters
SELV safety – 48V falls under Safety Extra Low Voltage, safer than higher voltage systems
About LiFePO₄ Technology
Safety – Very stable chemical structure, low risk of thermal runaway
Long cycle life – Over 4000 cycles, 5‑10 times longer than lead‑acid
Maintenance‑free – No acid/water refilling, no harmful gas emission
High energy density – More usable capacity in the same footprint
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.
