1. Safety Precautions
This section describes the safety information that must be observed when working with battery
packs. To prevent any damages, or personal injury, and to ensure the performance of the battery
packs, please read this section carefully and observe the safety precautions at all times.
1.1 Precautions
 It is very important and necessary to read the user manual carefully before installing or using
the product. Failure to do so or to follow any of the instructions or warnings in this document
can result in electrical shock, serious injury or death, and could damage the battery, or
potentially rendering it inoperable.
 If the battery pack is stored for long time, it is required to charge them every six months, and

LBSA 51.2V 105AH LIFEPO4 BATTERY PACK USER MANUAL www.LBSA.co.za
the SOC should be no less than 90%.
 Please recharged the battery pack within 12 hours, after fully discharged.
 All the battery pack terminals must be disconnected before any maintenance.
 Do not use cleaning solvents to clean battery pack.
 Do not expose battery pack to flammable or harsh chemicals, or corrosive gases or liquids.
 Do not paint any part of battery pack, include any internal or external components.
 Do not expose the battery pack to direct sunlight for extended periods of time.
 Do not connect battery pack with PV solar wiring directly.
 Do not insert any foreign object into any part of the battery pack.
1.2 Warning
 Do not touch the battery pack with wet hands.
 Do not crush, drop or puncture the battery pack.
 Always dispose of the battery pack according to local safety regulations.
 Store and recharge the battery pack in a manner in accordance with this user manual.
 Ensure reliable grounding.
 Do not reverse the polarity when installing.
 Do not short circuit the terminals, remove all jewellery items that could cause a short circuit
before installation and handling.
 Disconnect battery from power or loads, and then power off battery before installation and
maintenance.
 The battery packs should be not stacked more than specified numbers.
 Continued operation of a damaged battery pack can result in a fire.

2. Introduction
LBSA lithium iron phosphate battery pack is a household renewable energy storage solution
developed and produced by Lithium Batteries SA. After fully installation, it is a low-voltage DC
battery system with an operating voltage of 51.2V, and works with a low voltage inverter to realize
the goal of energy storage for home application.
The battery pack supports parallel connection to expand capacity, which can meet various capacity
requirements. It has 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.
2.1 Features
 Battery cell is 3.2V 105Ah aluminium case prismatic cell.
 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 charge and discharge state, and balance current and voltage of each cell.

LBSA 51.2V 105AH LIFEPO4 BATTERY PACK USER MANUAL www.LBSA.co.za
 Flexible configuration, max. 16 packs can be connected in parallel for expanding capacity and
power with 8 DIP switches.
 Working temperature range is from -20℃~50℃ (Charging 0℃~50℃; discharging -20℃~50℃
)
with excellent discharge performance and cycle life.

Power terminals: one pairs of power terminals to go directly to a single inverter if one pack is used.
If more than one pack is used the batteries must be connected to a busbar with equal length cable
to ensure there is equal discharge and charge between the batteries
Power cable uses 10.0mm lug to connect to the battery terminals.

2.4 Cell Features
2.4.1 Specifications
GFB 3.2V 100Ah lithium iron phosphate (LiFePO4) aluminium case prismatic rechargeable
battery cell.
Nominal Voltage 3.2V
Nominal Capacity 105Ah
Weight ≤2.25Kg
Self-discharge Rate ≤3.5% per month
Initial Internal
Resistance（1KHz） ≤0.35mΩ
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℃ room temperature, 100%DOD.

LBSA 51.2V 105AH LIFEPO4 BATTERY PACK USER MANUAL www.LBSA.co.za
 The real capacity of each single cell is 105Ah.
 The module inside comes with 16 cells in series.
2.5 Advanced Battery Management System (BMS) inside
The BMS is applied to monitor current, voltage, temperature, protection against over-charge, over-
discharge, over-current, over-temperature, under-temperature and short circuit. The BMS provides
cell balancing and current limitation during charging process to ensure a reliable safety and
performance.
The BMS will automatically adjust the Available capacity after evert full charge of 56v when
discharge.
This capacity will be influenced by the Temperature as the cells generally have less capacity
available under very cold temperatures.

 Over charge protection
 Over discharge protection
 Over current protection
 Cell balancing
