LBSA 5.3kWh 51.2V 104Ah LiFePO₄ Low-Voltage Lithium Battery
The LBSA 5.3kWh lithium iron phosphate battery is a low-voltage energy storage solution developed for residential solar and backup power systems. Designed around a 51.2V DC architecture, this battery integrates high-quality LiFePO₄ prismatic cells with an advanced Battery Management System to deliver safe, stable, and long-term energy storage.
This battery is intended for use with low-voltage hybrid and inverter-charger systems and is suitable for installations where reliability, controlled discharge, and modular expansion are required.
System Role and Typical Applications
The LBSA 5.3kWh battery stores electrical energy generated from solar PV systems and supplies power during grid outages, load shedding, or peak usage periods. It is commonly used in residential backup systems, hybrid solar installations, and small off-grid applications where daily cycling is expected.
This is a low-voltage battery and must not be connected to high-voltage inverter platforms.
51.2V Low-Voltage Battery Architecture
Operating at a nominal voltage of 51.2V, the battery fits within the standard 48V-class lithium battery category. This voltage range provides a balance between safety, efficiency, and broad inverter compatibility while allowing sufficient current delivery for residential loads.
LiFePO₄ Cell Technology and Cycle Life
The battery uses aluminum-cased prismatic lithium iron phosphate cells rated at 3.2V 104Ah per cell. LiFePO₄ chemistry is widely regarded for its thermal stability, resistance to thermal runaway, and long service life.
The battery is rated to retain at least 80% of its original capacity after 4800 cycles at 0.5C, 25°C, and 100% depth of discharge, making it suitable for long-term daily use.
Advanced Battery Management System
An integrated smart BMS continuously monitors voltage, current, temperature, and state of charge at both pack and cell level. The BMS provides protection against over-charge, over-discharge, over-current, over-temperature, under-temperature, and short-circuit conditions.
Cell balancing is performed during charge and discharge to maintain uniform cell health and extend overall battery lifespan.
LBSA 5.3kWh Battery Parallel Expansion and Scalability
The LBSA battery supports parallel connection of up to 16 identical battery units. Parallel systems must be connected via a central busbar with equal-length cables to ensure balanced current sharing across all batteries.
This modular approach allows system capacity to grow over time as energy requirements increase.
Inverter Communication and Compatibility
The battery supports CAN communication to compatible inverters and RS485 communication between parallel battery packs. This enables accurate state-of-charge reporting, controlled charging and discharging, and coordinated protection behaviour when used with supported inverter platforms.
LBSA 5.3kWh Battery Physical Design and Installation
The battery is housed in a durable metal enclosure designed for wall-mounted installation. Integrated DC circuit protection includes a 125A DC circuit breaker with shunt trip functionality.
The enclosure includes LED indicators for operating status, state of charge, and alarms, providing clear visual feedback during operation.
