Introduction

LBSA lithium iron phosphate battery pack is a household renewable energy storage solution developed and produced by Lithium Batteries SA. After full installation, it is a low-voltage DC battery system with an operating voltage of 25.6V and works with a low voltage inverter to realize the goal of energy storage for home applications.
The battery pack supports a parallel connection to expand capacity, which can meet various capacity requirements. It has a built-in battery management system (BMS), which can manage and monitor the pack and cells information including voltage, current, and temperature. What’s more, BMS can balance cells charging and discharging to extend cycle life.

Features

• The battery cell is a 3.2V 105Ah aluminum case prismatic cell.
• The battery cell is made from lithium iron phosphate (LiFePO4) with safety performance and longer cycle life.
• BMS has over-discharge, over-charge, over-current, high and low-temperature warning, and protection functions.
• BMS monitors the charge and discharge state and balances the current and voltage of each cell.
• Flexible configuration, max. 16 packs can be connected in parallel for expanding capacity and power with 8 DIP switches.
• The working temperature range is from -20°C-50°C (Charging 0°C-50t; discharging -20t-50t) with excellent discharge performance and cycle life.

Refer to the cell specification for more detailed information.
High-quality Grade A cells are inside the battery box
Judging by the current testing report below, if the battery pack charging and discharging at 0.2C, the battery pack could reach a cycle life of 6000 times or more at the remaining capacity of 80% capacity state at 25°C room temperature, 100%DOD.

• The real capacity of every single cell is 105Ah.
• The module inside comes with 2 cells in parallel and 8 of those pairs in series.

Advanced Battery Management System (BMS) inside

The BMS is applied to monitor current, voltage, temperature, and protection against over-charge, over-discharge, over-current, over-temperature, under- temperature, and short circuit. The BMS provides cell balancing and current limitations during the charging process to ensure reliable safety and performance.
The BMS will automatically adjust the Available capacity after every full charge of 28v when discharged. This capacity will be influenced by the Temperature as the cells generally have less capacity available under very cold temperatures.
2.5.1 BMS Functions

• Overcharge protection
• Over-discharge protection
• Over-current protection
• Cell balancing
• Temperature protection
• CAN communication to inverters and RS485 communication between battery packs

2.5.2 Compatible Inverters (with regards to CANbus Communication), all other inverters should have the charge and discharge cut-off set in accordance with section 2.2 of the Manual
