Renogy 48V 50Ah Smart Lithium Iron Phosphate Battery BMS

Remarkable & Reliable BMS System


The upgraded battery management system (BMS) not only protects the battery but also features high performance dual processors. This provides great load fluctuation resistance while maintaining balanced voltage across all cells.


The BMS system offers single cell temperature measurement discrepancy of ±1℃ and voltage measurement discrepancy of ≤5mV. This makes the Renogy 48V LiFePO4 one of the most reliable batteries out yet.


Powered by an upgraded intelligent BMS circuit, the Renogy 48V LiFePO4 battery is resistant to load and temperature fluctuations.



Auto-Balanced, ultra safe


With the auto-balancing feature, you can easily connect multiple batteries in parallel. By doing this, you can improve the average charging efficiency of your batteries over extended use.


With time and use, the battery’s chemical composition will start to decay. This will trigger the over voltage protection feature more often, preventing the battery from fully charging. To prevent this, Renogy's new auto-balancing function makes sure that all internal battery pouches charge consistently. This, improving battery's charging efficiency and providing an extended life cycle.

 48V 50Ah Renogy Smart Lithium Iron Phosphate Battery Superior Quality

Superior Quality


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


This battery met and exceeded the free drop test Electro Magnetic Compatibility testing, forced overcharge/discharge test and crash test. With more than 4,500 cycles, a minimum 10 year life span, it offers superior quality.




Charge anytime, anywhere with self-heating function


Introducing our groundbreaking self-heating function. This feature allows you to easily charge your batteries in cold conditions.


When connected to an input, the self-heating function will begin operation automatically when the battery temperature falls below 41°F (5°C).


48V 50Ah Renogy Smart Lithium Iron Phosphate Battery Self-heating Function


48V 50Ah Smart Lithium Iron Phosphate Battery Built-in Activation Switch

Built-in Activation Switch


With the built-inn activation switch, you no longer need an external switch connector. Activating and deactivating the battery can be easily done with one touch, minimizing the battery's internal power consumption.


You can control the deactivation process yourself, a helpful feature to avoid electrical sparks when installing your solar system.



Real-time Monitoring


The innovative RS485 communication ports enables your batteries to communicate with each other, with external devices and with host computers. Thanks to this feature, you can monitor the charging status in real-time.


You can use a Renogy Bluetooth Module BT2 to export the data into readable, useful information. You can then stream it straight to your cell phone or watch it live with a Renogy monitoring screen.

48V 50Ah Smart Lithium Iron Phosphate Battery Real-time Monitoring





For the normal operation of the self-heating function, a stable charge current greater than 3A is required.

Please make sure all cable connections are according to specifications. This will ensure good contact between cable lugs and terminals. It is very important not to over-tighten cable connections. This can cause terminal breakage and loose cable connections that can lead to terminal meltdown or fire.

DO NOT string the battery in series. ONLY connect batteries of the same manufacturer and model in parallel.

Even with the auto-balancing function, please avoid huge voltage differences between paralleled batteries. This will help avoid triggering the over-current protection.
