Renogy 48V/50Ah Smart LiFePO4 Deep Cycle Battery

The latest 48V Renogy Lithium Iron Phosphate Battery is taking the smart batteries to the next level. With built-in intelligent self-heating, you can keep your battery charged in cold environments effortlessly. The 48V nominal voltage ensures more than 4500 life cycle, low heat generation and high efficiency during high power transmission. The modular design easily scales to meet a range of configurations—making it improve the average charging efficiency for your batteries in the long term. The state-of-the-art battery management system (BMS) enables comprehensive protection features and real-time monitoring.

With the highest safety standards and five years of prorated warranty, your Renogy battery is the smart point for the future of your amazing off-grid living experience.

Remarkable BMS

With a single cell temperature measurement discrepancy of ±1℃ and voltage measurement discrepancy of ≤5mV, the new Renogy 48V LiFePO4 is our most reliable battery yet. Powered by an upgraded intelligent BMS circuit, the Renogy 48V LiFePO4 battery is resistant to load and temperature fluctuations.

Auto-Balancing Function

After extended use, the battery’s chemical composition will start to deteriorate, and the over-voltage protection function will be triggered more often, stopping it from fully charging. However, the latest Renogy auto-balancing function ensures that all internal battery pouches charge consistently, improving your battery’s charging efficiency and extending its service life.

Superior Quality

This battery has smashed the free drop test,ElectroMagnetic Compatibility testing, forced overcharge/discharge test,and crash test. With more than 4,500 cycles, a minimum 10 year life span, it's everything a quality battery should be.

Charge anytime, anywhere

Meet our revolutionary self-heating function. This technology allows you to charge your batteries in cold environments effortlessly. When connected to an input, the self-heating function will start operating automatically once the battery temperature drops below 41°F(5°C).

Built-in Activation Switch

Say goodbye to the old external switch connector. With a built-in switch button, activating and de-activiting the battery can all be done with one touch. This will minimise the battery's internal power consumption. Not to mention, you can avoid electrical sparks when installing your solar system by being able to control the de-activation process yourself.

Real-time Monitoring

With the improved RS485 UP Communication Port, your batteries will be able to communicate and transfer data in real time. Using a Renogy Bluetooth Module BT2 export the data into comprehensible information streamed straight to your cell phone, or watch it live with a Renogy monitoring screen.


  • The normal operation of the self-heating function requires a stable charge current greater than 3A
  • Please secure all cable connections to the proper specification in order to ensure good contact between the cable lugs and the terminals. Over-tightening cable connections can cause terminal breakage and loose cable connections can cause terminal meltdown or fire.
  • DO NOT string the battery in series. ONLY connect batteries of the same manufacturer and model in parallel.
  • Please avoid too high a voltage difference between paralleled batteries, despite the auto-balancing function, to avoid triggering the over-current protection.

Uncompromising Quality

Renogy’s latest 48V battery delivers a breakthrough in quality by offering an exceptional lifespan of more than 4500 cycles (reducing to 80% capacity after 4500 cycles), a 50A maximum discharge current, and most importantly, an extensive five year warranty.

Self-Heating Function

The intelligent self-heating function will start operating automatically once the battery’s core temperature drops below 41°F (5°C), effortlessly keeping your battery charged in cold environments.

Reliable BMS System

The upgraded battery management system (BMS) with high performance dual-processors provide load fluctuation resistance while maintaining balanced voltage across all cells.

Low Temperature Protection Function

The lithium battery has low temperature charging and discharging protection function. When the temperature is below 0℃, it will stop charging. When the temperature is below -20℃, it will stop discharging.

Auto-balancing Function

Easily connect multiple batteries in parallel with the auto-balancing function to improve the average charging efficiency of your batteries over extended use.

Real-time Monitor

Featuring advanced RS485 communication ports—your batteries will be able to communicate with each other, external devices and host computers allowing you to monitor the charging status in real-time. (A BT-2 Bluetooth Module or Monitoring Screen is needed).

Frequently Asked Questions

1. What are Renogy battery’s greatest advantages?
  • Firstly, our batteries use the most up to date pouch cell technology. Currently, there are a few battery brands on the market using pre-used battery cores, these have a negative impact on the battery’s life span and present safety risks. In addition, Renogy batteries feature, self-heating functions, an auto-balancing system and an advanced and efficient BMS system. Moreover, Renogy batteries have passed the free drop test,Electro Magnetic Compatibility testing, forced overcharge/discharge test,and crash test.
2. What exactly are pouch cells?
  • Soft pouch cells use a lightweight aluminum-polymer film to house the battery core, however most Li-ion batteries on the market today still use outdated hard metal battery casings. Comparing metal casings and pouch cells of the same capacity, pouch cells are substantially more light weight and have good cycle performance. When a pouch cell is damaged the gas and heat can escape through a sealing port, preventing further violent reactions. However, hard metal battery casings made from aluminum and steel are much more likely to explode when damaged.
3. My current RV is using a 12V system, if I upgrade to a 48V system what obvious life improvements will I see?
  • The most perceptive advantage of upgrading from 12V to 48V is that you will be able to use high-power electrical appliances in your RV. If you need to use high-power electrical appliances such as an air conditioner, refrigerator, or oven then a 48V battery will meet your energy needs and greatly enhance your off-grid living experience. Also, thinner cables can be used to connect the battery to the rest of this system, this will reduce transmission loss, save on space and improve the safety of your solar setup.
4. How long can this battery be used for?
  • This battery can complete 4500 full charge-discharge cycles and battery efficiency will drop to 80% of factory performance after this, however it can still be used with ease. If you live completely off-grid and charge and discharge the battery once a day it will last for more 10 years.
5. How many batteries can be connected together at once?
  • Up to 8 batteries can be connected in parallel, the auto-balancing function allows you to connect in parallel more safely.
6. I’ve never seen a switch button a battery before, what function does it have?
  • We have added one touch activation function to this battery. When the battery and BMS system aren’t needed it, they can be turned off with one touch, reducing wear and tear, making storage safer and extending battery life.

Buena compra

Al parecer es de buena calidad!

Kevin B.
Inexpensive and works well off grid

So far these batteries are handling my off-grid needs well. I purchased 4 and they are connected to 2 240 watt panels. They start charging and handle the load I put on them.

David C.
Lots of amperage and power

Plenty of backup power if you use a large enough inverter to utilize it.

Barbara S.
High quality and affordable.

This battery fits perfectly on its side under my kayak seat and has ample power for my Minn Kota i-pilot trolling motor, 60 lb. Thrust.

Gregory N.
Works Great!

I bought this battery for my bass fishing boat. I have a small boat and this is often the only way I power it. I am getting at least three times the life from each charge. My old battery was good for about two hours of constant use. Which would mean I was good for 3 to 4 hours depending on how much moving around I did. This battery can go all day. I have been out for 8 hours and it still had lots of juice left.
