Remarkable BMS
Auto-Balancing Function
Superior Quality
Charge anytime, anywhere
Built-in Activation Switch
Real-time Monitoring
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.
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
- 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.
- 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.
- 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.
- 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.
- Up to 8 batteries can be connected in parallel, the auto-balancing function allows you to connect in parallel more safely.
- 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.
