The BSLBATT B-LFP48-100E 3U is a high-capacity 51.2V 100Ah LiFePO4 battery designed for rack-mounted energy storage, solar power systems, backup power and other 48V-class applications.
With 5.12kWh of nominal energy storage, integrated battery management and a 3U server-rack form factor, it provides a scalable way to add substantial lithium storage without the footprint of a traditional floor-standing battery system.
The battery uses 16 prismatic 3.2V LiFePO4 cells in a 16S1P configuration and incorporates a 100A internal BMS, providing monitoring and protection for the battery pack. The manufacturer specifies more than 6,000 cycles at 25°C and a 10-year warranty.
Multiple batteries can also be connected in parallel, with the manufacturer's specification allowing up to 63 units, providing a theoretical system capacity of up to 322.56kWh.
The B-LFP48-100E 3U provides:
- 51.2V nominal voltage
- 100Ah capacity
- 5.12kWh nominal energy
- 5.12kWh specified usable capacity in the supplied datasheet
- LiFePO4 (Lithium Iron Phosphate) chemistry
- 16S1P cell configuration
- 100% specified depth of discharge
- 100A rated discharge current
- 5.12kW rated discharge power
This makes it suitable for applications where reliable, repeatable energy storage is required.

LiFePO4 Battery Technology
LiFePO4 is widely used for stationary energy storage because of its combination of cycle life, stability and energy density.
Compared with traditional lead-acid batteries, a LiFePO4 storage system can provide significantly more usable energy for its physical size and can be cycled much more frequently.
The BSLBATT B-LFP48-100E 3U is specified for more than 6,000 cycles at 25°C, making it suitable for regular daily cycling applications when installed and operated according to the manufacturer's requirements.
Integrated Battery Management System
The battery incorporates an internal 100A Battery Management System (BMS).
The BMS is designed to monitor and protect the battery during operation while providing battery communication and management functions.
Available communication interfaces include:
- RS232
- RS485
- CAN
- Wi-Fi (optional)
- Bluetooth (optional)
Communication compatibility should be confirmed with your selected inverter or energy management system before installation.
Rack-Mount Battery Design
The 3U rack-mount format makes the B-LFP48-100E suitable for installations where batteries are housed in a suitable equipment or battery rack.
This can provide a much cleaner and more scalable installation than individual floor-standing battery units.
Important: The battery weighs 46kg and should be installed in a rack or mounting arrangement capable of safely supporting its weight.
Ideal for Solar & Energy Storage
The BSLBATT 51.2V battery can be used as part of compatible solar and energy storage systems to store electricity for use when it is needed.
Typical applications include:
- Residential solar battery storage
- Off-grid solar systems
- Hybrid solar systems
- Commercial energy storage
- Backup power
- UPS systems
- Telecommunications backup
- Remote power systems
- Microgrid applications
- Data and communications infrastructure
