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.

50 Ah 12v Battery

Brad on Sep 20th 2022

So far so good. I use this battery in a small solar generator setup. A 120w panel with a 1100w modified sine inverter and this battery. I use it to complement my boondocking camping. Using the panel as pass-through charging it can handle 6 hours of crockpot cooking. It also charges my 18v power tool batteries on a non serviced remote work site. The whole thing fits into a medium size toolbox. Expect the panel.

Small but powerful, the installation is for a 12v refrigerator/freezer in my overland setup. Went from agm 2 days of backup to 5 days. Petit mais puissant! La batterie est pour mon camion d’overland. Je suis parti de AGM avec 2 jours d’autonomies et un poids de 68lbs, à 5 jours 15lbs !

Renogy lithium 50 watts

Jacques Chagnon on Jun 17th 2022

Je suis très satisfait de cet achat.Je m’en suis servi avec un moteur électrique d’une poussée de 46 les,et la charge a duré 6 heures.Le poids de cette batterie à 14.6 lbs comparé à 50 ou 60 livres pour les batteries conventionnelles en fait le meilleur allié du pêcheur.

CPAP pendant 7 jours

André Lemire on May 16th 2022

Merveilleux, encore 13 volts apres 7 jours sur mon CPAP donc encore capable pour plusieurs jours, Recharger apres 45 minutes avec le chargeur Renogy 20 A. (le CPAP sans humidification)

Great addition to a new teardrop trailer

Brian Taylor on Apr 12th 2022

Purchased recently to replace a similar size lead acid flooded battery. Difference in the weights of the two batteries is phenomenal. Now I have used it for a while, it’s much stronger at delivering power and it’s weight has positively changed the hitch weight on the trailer!
