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 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.
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.

    The battery arrived with a 90% SOC and packaging and battery were undamaged. I installed it inside the trailer yesterday and this morning it was happily at 100%. (Side note: The WFFCO autodect recognized it easily). I l also upgraded my inverter to the Renogy 2000w. and I've run the microwave a few times drawing almost 100 amps and it didn't even blink. The battery monitor is a breeze to install and has all sorts of great info displayed on it. I had and Renogy Rover 40 amp mppt charge controller for 5 yrs now along with their panels and suitcase panels and never had an issue with any of them. I opted to replace it with the 40amp rover elite and a monitor screen( the only model which you can get a remote screen for without getting into the Bluetooth stuff). I like that this battery is built with prismatic cells, not pouch cells and is a bargain at less than half the price of Battleborn batteries. I'll keep you posted as time progresses.

    12V 300AH Core Series Deep Cycle Lithium Battery

    Posted by Tom on Jan 9th 2024

    Purchased two of these to upgrade my older 12V 200AH AGM batteries. Made for a good replacement as they were the same size and fit into the cabinet made for the solar power system. Forgot how heavy the old AGM batteries were compared to the new lithium versions - wow. The self heating batteries should be a good fit for my off grid abode in northern Michigan. We rarely see enough sun during the winter to charge the batteries, but I hooked up a 75AMP AC-DC charger and these batteries just soak it up.
