FAQs — Renogy Lithium Iron Phosphate Battery 12 Volt 50 Ah (RNG-BATT-LFP-12-50-US)

Q: an you recommend a solar charge controller for this 50Ah battery?

Answer: When purchasing a solar charge controller, you must confirm that the controller is compatible with the lithium-iron phosphate battery. The Renogy Adventurer Li, Rover Li, and Wanderer Li charge controllers are all fully compatible with our lithium-iron phosphate batteries.

Q: Can this battery be combined with a 12V lead acid battery bank?

Answer: We highly recommend NOT stringing lithium batteries to any lead acid batteries. Otherwise, the battery will be damaged. When wiring batteries, it's recommended to connect batteries with the same type (lithium), same capacity (Ah), same voltage (V) from the same brand.

Q: Can I connect multiple batteries in series to build a 24V, 36V, or 48V system?

Answer: No, you can't. These Renogy 12V 50Ah lithium batteries do NOT support connecting in series. They are made ONLY for connecting in parallel using identical batteries, same type (lithium), same capacity (Ah), same voltage (V), same brand (Renogy).

Q: Can I use any 12V battery charger to charge this battery or does it have to be a specialized lithium charger?

Answer: You need to use a battery charger compatible with Lithium-Iron Phosphate deep cycle batteries to charge this battery, or it will be damaged. Renogy's 12V DC-DC and AC-DC battery chargers all support charging Lithium batteries, you can visit our website for more information.

Q: Can I leave this battery in cold weather? I live in my van and this battery will be in the cold. I was wondering if the cold will affect it?

Answer: This Renogy battery has different operating temperature ranges for charging and discharging. The operating temperature for discharging is -4℉~140℉ / -20℃~60℃. The operating temperature range for charging is 32℉~113℉ / 0℃~45℃. For optimal performance, we recommend using this battery at 73.4 ± 9℉ / 23 ± 5℃.

Q: Which capacity should I purchase for a minivan build? 50Ah or 100Ah? I'll be using it to run a 12V fridge, laptops, small TV, etc.

Answer: The capacity and quantity of batteries needed for your minivan build depend on your energy consumption. Renogy's Super Solar Calculator can help to calculate the amount of power needed in kWh and recommend a solar system accordingly. You can visit our Calculator website for more information.
