1.I have 4 Renogy 100W 12V solar panels. Will these work with this LiFePO4 battery, or is that too much wattage?
 
Yes, your 4 Renogy 100W 12V solar panels will work with the LiFePO4 battery. However, make sure that your solar charge controller can handle the total wattage output from the panels. Never connect solar panels directly to the battery without using a solar charge controller to protect both the battery and the panels. Contact us if you need help sizing 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 (using the same model of batteries) to achieve up to 40.96kWh.
3. How many Renogy 12V 300Ah Core Series Batteries can I connect at most?
 
You can connect up to 4 Renogy 12V 300Ah Core Series Batteries in series, up to 4 batteries in parallel, or up to 16 in a series-parallel connection. Ensure all batteries are the same model and capacity for proper performance.
4. How long will the Renogy Core Series Lithium Iron Phosphate Battery last?
 
Renogy 12V 300Ah Core Series Batteries can last up to 5000 cycles with an 80% depth of discharge (DOD). These batteries are designed with a 200A Battery Management System (BMS), IP65 protection, and a rugged structure, providing durable and reliable performance for years to come.
5. Can I pair a Bluetooth Module for this battery to monitor the battery status on my phone?
 
No, this battery is not compatible with a Bluetooth module. However, you can use a 500A Battery Monitor with Shunt (sold separately) to keep track of the battery status and ensure optimal operation.
6. How do I recharge my LiFePO4 batteries?
 
You can recharge your LiFePO4 batteries using solar power, a DC-DC battery charger, or an AC-DC charger. We recommend using a solar charge controller/charger that is specifically designed to be compatible with lithium iron phosphate batteries for safe and efficient charging.

on the ball

From day one when I ordered a eahora romeo 2 2025 off grid lux has been in constant contact . From shipping the bike to after care I haven't had issues at all . They even called me to check on an issue I had and I actually spoke to a person , who was great by the way . Customer service has fallen to the big internet conglomerates but I didn't feel that way with the purchase , they have really tried to take care of me and answered every question I've asked , even ones that are stated on the site . Im happy I went with them .I hope I can purchase other stuff in the future here .
The products won't be flawless but their customer service is . Thanks again Greg

Extra battery for Ecotric Leopard

I bought an extra battery to increase my ebike range. Of all the sites I looked at, I was sure this one would fit my battery mount because it was labeled correctly. Not true of other sites. They shipped quickly and the battery was packed properly. Good business--would easily buy from this site again.

Excellent customer service

The whole process from ordering through receipt with Off Grid Lux was seamless. They responded quickly to our initial questions and helped us decide on the best product to suit our needs. There was a small hiccup with the shipment delivery (the fault of the carrier) and Odd Grid Lux contacted the carrier immediately and had our issue resolved. We researched many vendors before deciding on Off Grid Lux and their pricing and customer service cannot be beat.
