The Renogy Core Mini 12V 300Ah LiFePO4 Battery is a compact deep-cycle lithium battery for RVs, vans, boats, campers, home backup planning, and off-grid power systems. It delivers 3840Wh of rated energy in a smaller 55.1 lb case, making it easier to place where space and handling matter. Built-in low-temperature protection helps limit charging below 32°F and discharging below -4°F, giving the battery added protection in cold-weather conditions. Grade-A prismatic lithium iron phosphate cells support 5000+ cycles at 80% depth of discharge for long-term energy storage planning. Series and parallel support up to 4S4P allows larger battery banks when installed with compatible matching batteries, correct protection equipment, and proper system design.
The Core Mini design gives users 300Ah rated capacity and 3840Wh of energy storage without the larger footprint of many high-capacity batteries. Its 15.12" x 7.64" x 9.96" case helps support cleaner layouts in battery compartments, mobile power systems, and properly planned home backup builds.
The built-in battery management system helps protect the battery by limiting charging below 32°F and discharging below -4°F. This matters for RV, van, marine, and off-grid users who may store or operate equipment in colder conditions.
At 55.1 lb, this Renogy Core Mini battery is built to be easier to move, position, and install than many heavier deep-cycle battery options. The lithium iron phosphate chemistry, Grade-A prismatic cells, and IP65 protection rating support dependable use in properly configured power systems.
The battery supports series and parallel connection up to 4S4P, giving system designers flexibility for larger storage configurations. Final battery matching, cable sizing, fusing, charger settings, inverter compatibility, and clearance should be confirmed against current Renogy documentation before installation.
The compact Core Mini form factor is useful where battery space is limited but higher storage capacity is still needed. It is suited for properly sized RV, van, camper, boat, and backup energy systems that require dependable lithium storage.
Renogy lists installation clearance guidance of 1.97" to 3.94" above the battery and at least 7.87" on the busbar side. These spacing requirements should be checked during layout planning to support safe access, clean wiring, and proper system serviceability.
