The Renogy 4 Pack Core Mini 12V 300Ah LiFePO4 Batteries gives RV, van, marine, home backup, and off-grid power systems a larger lithium storage foundation using four compact 300Ah batteries. Each battery provides 3840Wh of rated energy, giving the 4-pack a combined 15.36kWh nominal battery capacity before system losses, reserve settings, and load demand are considered. The Core Mini design keeps each battery at 55.1 lb with a compact 15.12" x 7.64" x 9.96" footprint, helping support tighter battery compartments and cleaner power layouts. Built-in low-temperature protection helps limit charging below 32°F and discharging below -4°F, adding protection for cold-weather storage and use. Grade-A prismatic lithium iron phosphate cells support 5000+ cycles at 80% depth of discharge, while supported series and parallel configurations allow expansion planning up to 4S4P when installed with matching batteries and compatible system equipment.
This Renogy 4-pack includes four Core Mini 12V 300Ah lithium iron phosphate batteries for properly designed battery banks. With 3840Wh per battery, the full 4-pack provides 15.36kWh of nominal storage capacity for supported RV, van, marine, home backup, and off-grid energy systems.
Each battery uses a smaller case that helps save space in tight compartments, battery boxes, and mobile power setups. The compact footprint leaves more room for wiring access, busbar planning, inspection clearance, and system serviceability when the installation is laid out correctly.
The built-in battery management system helps protect each battery by limiting charging below 32°F and discharging below -4°F. This is useful for systems that may be stored, transported, or operated in colder conditions, while still requiring proper charger settings, temperature awareness, and installation planning.
Renogy lists series and parallel support up to 4S4P, allowing properly matched batteries to be configured for larger supported systems. Final battery matching, cable sizing, fusing, inverter compatibility, charger settings, torque, and clearance should be confirmed against current Renogy documentation before installation.
The 4-pack format is suited for larger power storage builds where a single battery is not enough capacity. Each Core Mini battery keeps the same compact case size, making it easier to plan multiple-battery layouts without adding unnecessary bulk.
Renogy lists installation clearance guidance of 1.97" to 3.94" above the battery and at least 7.87" on the busbar side. These clearance details should be considered for each battery in the bank to support safe access, proper wiring, and long-term serviceability.
