5,000+ deep cycles, 200A BMS, IP65 waterproofing — in a compact form that fits 8D and 4D battery boxes.
The Renogy 12V 200Ah LiFePO4 Battery with Low-Temperature Protection (model RBT12200LFP-M-G1-US, also known as the Core Mini) is a compact, deep-cycle lithium iron phosphate battery built for RV, marine, solar, and off-grid applications. Delivering 2,560Wh of usable energy in a body that is 21% smaller than comparable LFP batteries and one-third the size of an equivalent lead-acid battery, it pairs a robust 200A battery management system with automatic low-temperature cut-off — stopping charge and discharge before cold weather can cause damage, with zero manual intervention required.
Engineered for demanding environments, the Core Mini combines smart battery management, rugged construction, and a compact form factor that opens up installation options lead-acid simply can't match.
The built-in 200A battery management system guards against overcharge, over-discharge, over-current, and short circuits. A 380A peak discharge rating (10 seconds) handles the surge demand of microwaves, inverters, and motors without flinching.
The BMS automatically pauses charging below 32°F (0°C) and discharging below -4°F (-20°C), preventing cold-weather cell damage without any manual intervention. You stay focused on the adventure; the battery handles itself.
Grade-A prismatic LiFePO4 cells deliver 5,000+ cycles at 80% depth of discharge, compared to the 300–500 cycles typical of lead-acid batteries. Over a decade of daily use is realistic, dramatically reducing your cost-per-cycle.
At 15.12 × 7.64 × 9.96 in, the Core Mini is 21% more compact than comparable LFP batteries and one-third the size of an equivalent lead-acid unit. It fits standard 8D and 4D battery enclosures, freeing up space and simplifying installs in tight RV and marine compartments.
An IP65-rated enclosure combined with metal cell spacers resists moisture, dust, and the constant vibration of rough roads and choppy water. Whether you're crossing a rutted trail or riding ocean swells, the internals stay protected.
A 99% round-trip efficiency and less than 3% monthly self-discharge mean nearly every watt your solar panels or charger puts in is available when you need it. Compare that to lead-acid, which typically loses 15–20% per round-trip cycle.
The Core Mini is designed to grow with your power needs. Wire up to four batteries in series to build a 24V, 36V, or 48V system, and up to four in parallel to expand capacity — a maximum 4S4P configuration can deliver up to 40.96kWh of storage. When connected via the optional Renogy 300A Battery Shunt (sold separately), you can monitor voltage, current, and battery status in real time through the Renogy app or a compatible display.

The battery has a rated capacity of 200Ah and listed energy of 2,560Wh. Actual usable energy depends on system settings, inverter efficiency, load demand, temperature, wiring, and the selected depth of discharge. Renogy lists the cycle-life rating at 5,000 cycles under 80% depth of discharge and 80% end-of-life test conditions.
The BMS automatically cuts off charging when cell temperature drops below 32°F (0°C) and cuts off discharging below -4°F (-20°C), preventing cold-induced cell damage. This is a protective cut-off, not active heating — the battery will not charge in sub-freezing conditions until it warms up. If you need to charge in cold environments without waiting, consider Renogy's self-heating Pro Series battery instead. For cold-weather camping where you're generating heat inside the vehicle, this battery's automatic protection is typically sufficient.
Yes. You can connect up to four batteries in series (for 24V, 36V, or 48V systems) and up to four in parallel (to expand total capacity). The maximum supported configuration is 4S4P — four in series and four in parallel — yielding a maximum bank of 40.96kWh. When wiring multiple batteries, use cables of identical length and gauge on all connections to ensure balanced current distribution.
No — the Core Mini does not include Bluetooth connectivity and is not compatible with the Renogy Bluetooth module. For real-time monitoring of voltage, current, and state of charge, pair it with the Renogy 300A Battery Shunt (sold separately), which connects to the Renogy app or a compatible Renogy ONE Core display.
The Core Mini measures 15.12 × 7.64 × 9.96 in (384 × 194 × 253 mm) and is designed to fit standard 8D and 4D battery enclosures. Renogy recommends maintaining a clearance of at least 1.97–3.94 in (5–10 cm) above the battery and at least 7.87 in (20 cm) on the busbar side for ventilation and easy connection access.
Use a charger, DC-DC charger, or solar charge controller that is compatible with lithium iron phosphate batteries. Do not connect solar panels directly to the battery without a properly sized solar charge controller. The battery accepts up to 100A maximum continuous charge current, with a listed voltage range of 10V to 14.6V.
The Core Mini is physically about one-third the size of a comparable 12V 200Ah lead-acid battery and significantly lighter. Because LiFePO4 supports 100% DOD versus the 50% practical limit of lead-acid, you effectively get twice the usable energy from the same rated capacity. The round-trip efficiency of 99% versus roughly 80–85% for lead-acid means less energy is wasted per charge cycle. Lead-acid batteries typically last 300–500 cycles; the Core Mini is rated for 5,000+ cycles, making it substantially more economical over its service life despite a higher upfront cost.
The battery supports a continuous discharge of 200A and a peak discharge of 380A for up to 10 seconds. When paired with an appropriately sized pure sine wave inverter, this is sufficient to handle the high startup surge of appliances like microwaves, refrigerators, and air compressors. Always size your inverter and wiring to the battery's output rating and your appliance's startup current requirements.
