The Renogy 12V 300Ah Deep Cycle Lithium Iron Phosphate Battery with Self-Heating from the Core Series is a high-capacity LiFePO4 battery meant for RVs, vans, cabins, and off-grid setups that need a large energy reserve in every season. Compared with a 200Ah lithium battery it offers roughly 59% more usable power, and it is rated to keep going for thousands of cycles, far outlasting a conventional lead-acid bank.

Cold weather is handled by 200W of built-in heating elements that warm the cells before charging, while the battery management system cuts off charging at low temperatures to protect the cells. The rugged, IP65-rated housing is built to shrug off road vibration, dust, and moisture, which makes it a good fit for overlanding rigs and outdoor installations.

Systems can grow along with your needs: batteries can be wired in series to reach 24V, 36V, or 48V, in parallel for more capacity, or in a combined series-parallel layout of up to 16 units. Charging works through solar with a lithium-compatible controller, a DC-DC charger, or an AC-DC charger.

I have 4 renogy 100w 12v solar panels. will these work with this lifepo4 battery or is that too much wattage?
Yes, but please make sure that your solar charge controller is capable of handling the power your solar panels can output. do not connect solar panels directly to batteries without a solar charge controller.
Can this battery be used in series to build a 48-volt system?
Yes. renogy 12v core series batteries can be connected in series to ramp up voltage for a 24v, 36v, or 48v off-grid power system. you can also consider wiring batteries in series first and then wire sets of batteries (same models required) in parallel for maximum power up to 40.96kwh.
How many renogy 12v 300ah core series batteries can i connect?
The core series batteries support versatile connections, including series, parallel, and series-parallel connection. you can connect up to 4 batteries in series, 4 in parallel, or 16 in the series-parallel connection. batteries of the same model and similar capacity are required.
How long will the renogy core series lithium iron phosphate battery last?
Renogy 12v 300ah core series batteries are capable of delivering 5000 cycles with a recommended 80% depth of discharge (dod). meanwhile, these batteries combine a true 200a battery management system (bms), ip65 protection, and rugged structure design to brace for challenges wherever you go.
Can i pair a bluetooth module for this battery to monitor the battery status on the phone?
No. this battery is not compatible with the bluetooth module. you can use a 500a battery monitor with shunt (sold separately) to keep track of battery status.
How do i recharge my lifepo4 batteries?
Whether you prefer charging batteries via solar, a dc-dc battery charger, or an ac-dc charger, we highly recommend a solar charge controller/charger that is compatible with lithium iron phosphate batteries.
