48V 50Ah Smart Lithium Iron Phosphate Battery

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.

NOTE

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.

Warranty Information

1. What are Renogy 48v battery’s greatest advantages?

Firstly, Renogy 48 volt lithium batteries apply up-to-date pouch cell technology. Some batteries on the market use used battery cores, which hurts the battery’s life span and presents safety risks. In addition, Renogy 48v lithium ion batteries feature self-heating functions, an auto-balancing system, and an advanced and efficient BMS system. Moreover, Renogy 48v batteries have passed the free drop test, elector-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 advantage of upgrading from 12V to 48V is that you can use high-power electrical appliances in your RV. Suppose you need to use high-power electrical appliances such as an air conditioner, refrigerator, or oven. 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 48v LiFePO4 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 48v lithium ion battery be used for?

This 48v battery can complete 4500 full charge-discharge cycles, and 48 v battery efficiency will drop to 80% of factory performance after this. If you live entirely off-grid and charge and discharge the 48 volt lithium battery once a day, it will last for more than ten years.

5. How many 48v lithium ion batteries can be connected together at once?

Up to 8 48v lithium ion 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 48 volt lithium ion battery before, what function does it have?

We have added a one-touch activation function to this battery. When the 48v lithium battery and BMS system aren’t needed, they can be turned off with one touch, reducing wear and tear, making storage safer, and extending 48v lithium battery’s lifespan.

7. Is 48 volt lithium battery suitable for a golf cart?

Yes, Renogy 48 volt lithium batteries make perfect 48v golf cart batteries. Over lead acid and AGM batteries, 48v lithium golf cart batteries provide a number of benefits. One is that they are significantly lighter. They also don't need to be maintained. Due to their better efficiency and longer longevity, 48v golf cart batteries are also less expensive in the long run.
