Renogy Core Mini - 12.8-Volt 300Ah Deep Cycle LiFePO4 Battery with Low-Temperature Protection
Build an energy reserve that fits your system
Limited battery space and an unreliable state of charge can cut a trip short or leave an off-grid workspace without power. This Renogy battery gives you a defined storage capacity to plan around, with the chemistry and features identified below. Choose it for the actual DC system, charging equipment and installation space you have.
Choose it for your actual loads and installation
Capacity and available output solve different problems. Amp-hours describe stored charge at the specified conditions; the battery’s discharge-current limit, cables, fuses and inverter determine which loads can run. Add your loads and operating hours before selecting a pack size, and allow for conversion losses and reserve rather than assuming a fixed appliance runtime.
Model features that affect your choice
- Lithium iron phosphate (LiFePO4) chemistry
- Low-temperature protection is specified for this model

Check the fit and what is included
Check the charger profile, charge-current setting, battery-management protections and cold-weather limits for this exact model. A low-temperature cut-off prevents charging outside its range; it is not the same feature as a self-heating battery. Connect batteries in series or parallel only as permitted by the model instructions, using matching units and appropriate protection.
