    • If the battery's Battery Management System (BMS) is activated and the battery voltage shows 0V, you must use a compatible Li charger to reactivate this battery.
    • Make sure to screw in the battery terminals tightly. Loose battery terminals will cause heat build-up and cause damage to the battery.
    • DO NOT string these batteries in series. They are made ONLY for wiring in parallel using identical batteries.
    • Due to its own chemical characteristics, lithium batteries are not allowed to be charged below 0°C. Therefore, if you choose a lithium battery without internal heating function, it is normal that the lithium battery cannot be charged below 0℃ for safety reasons. Therefore, we recommend that you do not discharge the battery for a long time below 0℃, which will possibly lead to over discharge of the battery.

1.Can you recommend a solar charge controller for this 50Ah battery?

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.

2. Can this battery be combined with a 12V lead acid battery bank?

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.

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

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).

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

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.

5. 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?

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℃.

6. 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.

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.

7. How should I handle the battery after it arrives?

When you receive your battery, please be aware that it may have a low State of Charge (SOC) due to the transportation and storage process. To ensure its optimal performance, we recommend charging the battery right away to avoid over-discharge. If you plan to store the battery for an extended period without usage, we suggest charging it to a SOC of 30% to 50% and performing maintenance every three months. These steps will help maintain its functionality and performance over time.

    50ah lithium batts

    Posted by J. Saraceno on Jan 6th 2022

    Renogy was kind enough to horror the sale price at the time I purchased since I had missed it by a week. Great job to the renogy group. Two 50ah lithium in my conversion van and their 1000 watt inverter, and off we go to the state parks. Thank you renogy J. Saraceno

    Amazing power for size and weight!

    Posted by manny114 on Jun 21st 2021

    2 of these fit perfectly in a cabinet of my RV hooked up to 2 of the 100w Renogy solar panels. They're a bit expensive, but after using these I'd never go back to lead acid again!
