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 Mini 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 61.44kWh.

3. How many Renogy 12V 300Ah Core Mini Series Batteries can I connect at most?

The Core Mini 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 Mini Series Lithium Iron Phosphate Battery last?

Renogy 12V 300Ah Core Mini 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 structural 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.

Surprisingly Light but Very Powerful

I was not expecting something this light to deliver such solid performance. Easily carried and installed on my own. I called Renogy just to confirm I had the right setup, and the technician I spoke to was incredibly knowledgeable and patient. Everything about this product and company shows care and professionalism. Highly recommended.

Quality You Can Feel

We travel around the UK in our motorhome quite regularly, and having a dependable energy source is crucial. This Core Mini battery has exceeded our expectations. Even after days without hookup, we still have plenty of power left for our fridge, lights, and mobile charging. It is lighter than anything we have used before, and that really helps when loading it into tight spaces.

Simple Setup for First Time Users

This is my first lithium battery and it was incredibly easy to set up. Only two cables to connect and I was good to go. We often use it with solar panels and it charges fast. Great for temporary setups.

Great Battery and Even Better Service

From the moment I placed my order, everything about this purchase has been spot on. The battery arrived ahead of schedule. I installed it in my campervan alongside a Renogy inverter and MPPT controller. The whole system came together beautifully. Top class product backed by top class people.
