The Renogy Core Mini 12V 300Ah LiFePO4 Battery with Low-Temperature Protection is a compact lithium iron phosphate battery built for RVs, vans, campers, boats, home energy storage planning, and properly designed off-grid battery systems where capacity, weight, and installation space matter. This battery provides 300Ah rated capacity, 3840Wh nominal energy, and a listed 200A maximum discharge current for properly designed 12V systems. Its built-in low-temperature protection pauses charging below 32°F and discharging below -4°F, helping protect the battery in colder operating conditions. Renogy describes this Core Mini model as 31% smaller than other 12V 300Ah LFP batteries and lists it at 55.1 lb with a compact 15.12" x 7.64" x 9.96" footprint. Final charger settings, inverter sizing, cable gauge, fusing, terminal torque, series/parallel configuration, and installation clearance should be confirmed against current Renogy documentation.
The Renogy Core Mini 300Ah battery is designed for users who need larger 12V storage without taking up unnecessary battery-compartment space. With 3840Wh of nominal energy and a compact case size, it supports properly planned RV, boat, van, camper, cabin, and home energy storage systems when designed around compatible equipment.
The built-in battery management system includes low-temperature protection that pauses charging below 32°F and discharging below -4°F. This helps reduce cold-weather battery risk, but owners should still follow Renogy’s charging, storage, and operating guidance in freezing conditions.
This battery is listed with a 150A maximum charge current, 200A maximum discharge current, and 380A peak discharge current for 10 seconds. Those ratings support higher-output 12V system planning when the battery is paired with compatible chargers, inverters, cables, fuses, and protection equipment.
Renogy lists series and parallel connection support up to 4S4P, with expansion up to 61.44kWh when configured according to Renogy guidance. Batteries should be matched, balanced, wired, fused, and installed according to Renogy’s latest instructions before operation.

The Renogy Core Mini 300Ah battery is built for users who need more lithium storage in a smaller, lighter 12V package. It is best used as part of a complete system with compatible charging equipment, inverter capacity, wiring, and circuit protection.
Before installation, leave clearance above the battery and additional space near the busbar side as Renogy recommends. Confirm terminal bolt size, torque, cable routing, battery orientation, and system expansion limits before final setup.
