Rich Solar RS-B4811 48V 100Ah LiFePO4 Lithium Battery

The Rich Solar RS-B4811 is a 48V 100Ah lithium iron phosphate battery built for off-grid solar systems, backup power, battery storage, cabins, workshops, and larger 48V inverter setups. With 4.8kWh of energy storage, 7,000 charge and discharge cycles, built-in BMS protection, and parallel expansion support, it gives solar power systems a long-life battery foundation.

48V 100Ah battery 4.8kWh LiFePO4 storage 7,000 cycles Built-in smart BMS

4.8kWh Energy storage capacity from a 48V 100Ah lithium iron phosphate battery.

7,000 Charge and discharge cycle rating for long-term energy storage use.

100A Maximum charge and discharge current for compatible 48V systems.

20 Years Designed for a long service life when properly installed and maintained.

Product Overview

The Rich Solar RS-B4811 is designed for customers who need dependable 48V battery storage for solar, backup power, and off-grid energy systems. Compared to many older battery technologies, LiFePO4 chemistry offers longer cycle life, lower maintenance needs, stable output voltage, and stronger thermal and chemical stability.

This battery is a practical fit for 48V solar inverter systems, cabin power setups, remote buildings, backup power systems, and larger battery banks where long life, safety protection, and expandable storage are important. It can be connected in parallel for larger capacity when the system is designed and configured correctly.

The built-in smart battery management system helps protect the battery from overcharging, over-discharging, overcurrent, short circuits, and high or low temperature conditions.

BMS Safety Protection

The RS-B4811 includes a sophisticated battery management system designed to monitor and protect the battery during charging, discharging, and daily system operation. This helps support safer long-term performance in properly designed solar and backup power systems.

Overcharge Protection Helps protect the battery from charging beyond safe operating limits.

Over-Discharge Protection Helps prevent the battery from being discharged below safe voltage levels.

Short-Circuit Protection Built-in protection helps guard against short-circuit and overcurrent conditions.

Temperature Disconnects High and low temperature disconnects help protect the battery in demanding environments.

Cell Isolation Design Each cell is fused so an unlikely cell failure can be isolated to help reduce further damage.

LiFePO4 Stability The battery chemistry is designed for strong thermal and chemical stability.
