Frequently Asked Questions
1. 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. Feel free to contact us if you have questions about how to size the solar charge controller for your system.
2. 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 increase the voltage to 24V, 36V, or 48V for an off-grid power system. For maximum power output, you can first wire the batteries in series, then connect the sets of batteries in parallel (do use batteries of the same model and generation) to achieve up to 61.44kWh.
3. How many Renogy 12V 300Ah Core Series Batteries can I connect at most?
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.
4. 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.
5. 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.
6. How to 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.
7. Is it compatible with Renogy ONE?
No. This battery is not compatible with Renogy ONE currently. You can use a 500A Battery Monitor With Shunt (sold separately) to keep track of battery status.
