Renogy Core Mini LiFePO4 12.8V Lithium House Battery

The Renogy Core Mini is a 12.8V lithium iron phosphate (LiFePO4) house battery built for overlanding rigs, teardrop trailers, compact RVs, and kayak fishing setups where battery compartment space is tight. An IP65-rated enclosure, built-in low-temperature charging cut-off, and vibration-resistant metal cell spacers make it suited to rough-road and all-weather use. The Core Mini is available in 100Ah, 200Ah, and 300Ah capacities; detailed specifications below reflect the 100Ah variant, which is the smallest 12.8V 100Ah LFP battery in Renogy's lineup at Group 22NF size.

Compact Footprint, Multi-Orientation Mounting

The Core Mini's Group 22NF form factor (9.02 x 5.43 x 8.39 in for the 100Ah) is designed for battery bays and compartments where a full-size group battery will not fit. Multi-orientation mounting means the battery can be positioned to match the available space in a van build, trailer tongue box, or under-seat compartment rather than forcing a single fixed orientation. Allow 2–4 inches of clearance above the battery and 8 inches on the busbar side for safe installation.

Low-Temperature Cut-Off for Winter Operation

The Core Mini includes built-in low-temperature charging protection that prevents the battery from accepting a charge below 32°F (0°C). Charging a lithium iron phosphate cell below freezing can cause permanent internal damage; the cut-off removes that risk without requiring an external controller setting or manual intervention. Discharge remains available down to -4°F (-20°C), so the battery can still power loads in cold conditions even when charging is suspended.

5000-Cycle Lifespan and 300A Peak Surge (100Ah Variant)

The 100Ah Core Mini is rated for 5000 cycles at 80% depth of discharge before reaching 80% end-of-life capacity. That cycle rating represents a meaningful lifespan advantage over lead-acid batteries in the same footprint. A 300A peak discharge current (5-second surge) supports high-demand appliance start-up, such as a compressor fridge or trolling motor, without the battery management system tripping under the inrush load. Maximum continuous charge and discharge current for the 100Ah variant is 100A each.

Features

• IP65 Protection: dust-tight and water-jet resistant enclosure for all-weather durability
• Built-In Low-Temperature Cut-Off: suspends charging below 32°F (0°C) to protect cell integrity
• Vibration-Resistant Design: metal cell spacers prevent internal cell movement on rough terrain or choppy water
• Multi-Orientation Mounting: installs in multiple positions to fit tight or unconventional battery bays
• Series and Parallel Expandability: supports up to 4S4P configuration; up to 16 batteries can be connected for expanded capacity (100Ah variant)
• Battery Shunt Compatible: works with the Renogy 300A Battery Shunt (sold separately) for remote state-of-charge monitoring via the DC Home app

Specifications

Who This Is For and Isn't

The Renogy Core Mini LiFePO4 battery suits overlanders, van builders, teardrop trailer owners, and kayak anglers who need a compact 12V lithium house battery in a tight or unconventional battery bay. The built-in low-temperature cut-off makes it a practical choice for four-season use without relying on a charger with a dedicated cold-weather lithium profile.

The Core Mini does not include a Bluetooth port; real-time state-of-charge monitoring requires a separately purchased Renogy 300A Battery Shunt. Specifications for the 200Ah and 300Ah variants, including dimensions, weight, max charge and discharge current, and certifications, are not published in the current product listing and should be confirmed before purchase if those figures are decision-critical.

Common Questions

Can the Core Mini 100Ah battery be connected in series for a 24V system?

Yes. Renogy Core Mini 12.8V 100Ah batteries can be connected in series to build a 24V off-grid power system. Up to 16 batteries of the same model and similar capacity can be connected in series and parallel, expanding total capacity to 20.48kWh for the 100Ah variant.

Does the Core Mini battery have low-temperature charging protection?

Yes. The Renogy Core Mini LiFePO4 battery has built-in low-temperature charging cut-off that prevents the battery from accepting a charge below 32°F (0°C). This protection is built into the battery management system and does not require a separate controller setting.

Can I monitor the Core Mini's state of charge via a smartphone app?

The Core Mini battery does not have a Bluetooth port for a Bluetooth module. State-of-charge monitoring is possible by connecting the battery to a Renogy 300A Battery Shunt (sold separately), which transmits data to the DC Home app via Bluetooth.

What clearance does the Core Mini require during installation?

Renogy specifies 2–4 inches of clearance above the Core Mini battery and 8 inches of clearance on the busbar side. Multi-orientation mounting allows the battery to be positioned to match the available space in a van build, trailer tongue box, or other tight compartment.

What charger types are compatible with the Core Mini LiFePO4 battery?

The Core Mini LiFePO4 battery is compatible with solar charge controllers, DC-DC battery chargers, and AC-DC chargers. Renogy recommends using a charger or solar charge controller with a lithium iron phosphate charging profile to ensure proper charge voltage and cut-off behavior.
