Renogy CORE Mini 12.8V 300Ah LiFePO4 Battery
The Renogy CORE Mini 300Ah packs 3,840Wh of usable off-grid storage into a compact 55.1-pound battery. If you are replacing a bulky lead-acid bank in an RV, boat, cabin, van, or solar system, this is the straightforward high-capacity option: fewer batteries, fewer cable connections, and a lot less weight.
Its built-in 200A BMS includes low-temperature charging protection, and the IP65 housing is made for real installations where dust, moisture, and vibration are part of the job. Unlike the PRO models, this CORE Mini can be wired in series, parallel, or a 4S4P arrangement with matching batteries.
Key Features
- 12.8V, 300Ah capacity with 3,840Wh of stored energy
- Compact footprint and 55.1-pound weight
- 200A BMS with automatic low-temperature charging cutoff
- 5000-cycle design life at 80% depth of discharge
- IP65 water- and dust-resistant construction
- Supports series, parallel, and series-parallel banks up to 4S4P
- Expandable with matching batteries to as much as 61.44kWh
- 5-year prorated material and workmanship warranty
Best Uses
- Large RV and fifth-wheel battery upgrades
- Marine house banks and onboard electronics
- Cabins, tiny homes, and off-grid solar storage
- Van conversions with limited installation space
- 12V, 24V, 36V, or 48V systems built with matching batteries

Frequently Asked Questions
Can this battery be used in a 48V system?
Yes. Four matching CORE Mini 300Ah batteries may be connected in series for a 48V nominal bank. Renogy also supports parallel and 4S4P configurations.
Does it have self-heating?
No. This model uses low-temperature cutoff protection rather than an internal heater. Charging is blocked below 32°F to protect the cells.
How much energy does one battery store?
One battery stores approximately 3.84kWh. Actual appliance runtime depends on inverter efficiency, load, wiring, temperature, and the depth of discharge used.
Can I mix it with a different brand or capacity?
No. A multi-battery bank should use the same model, age, voltage, and capacity. Mixing batteries can create imbalance and unsafe operating conditions.
Can solar panels charge it directly?
No. Use a properly rated LiFePO4-compatible solar charge controller sized for the array voltage and current.
