Renogy Core 12V 300Ah LiFePO4 Battery (Self-Heating)
Reliable, all-weather power for RVs, cabins, boats, and off-grid living
The Renogy Core 12V 300Ah LiFePO4 battery delivers high-capacity, long-lasting energy with built-in heating and robust protections so you can stay powered in cold or rough conditions. It’s designed for flexible bank configurations and heavy-duty use—backed by a 5-year warranty and around-the-clock support.
Benefits
- Keep devices and appliances running longer during trips or outages so you spend more time living comfortably and less time worrying about power.
- Maintain reliable charging and usable capacity in cold weather thanks to the self-heating system, reducing downtime and battery replacements.
- Fewer maintenance hassles and longer service life compared with lead-acid batteries, saving time and replacement cost over years of use.
- Flexible connection options (series, parallel, or series-parallel) let you scale voltage and capacity to match your system needs without complex workarounds.
- Clear installation guidance and local support give you confidence during setup and troubleshooting so you can get back to your plans faster.
Features
- 12V 300Ah LiFePO4 chemistry with EV-grade cells for consistent long-term performance.
- Integrated Battery Management System (BMS) with low-temperature cut-off and 200A protection.
- Industry-leading 200W heating elements that warm the battery faster than typical heated batteries.
- Self-heating function that activates at 32°F (0°C) when each battery receives a stable charge current >10A.
- Support for series, parallel, or series-parallel connections to build 12V, 24V, 36V, 48V, or larger banks.
- Rugged mechanical structure and shock-resistant design for protection during transport and field use.
- IP65-rated protection for dust and water resistance in many outdoor and mobile applications.
- Not compatible with a Bluetooth module; compatible with a 500A battery monitor with shunt (sold separately).
