USER MANUAL
This manual introduces the LBSA Smart Battery by Lithium Batteries SA. Please read this manual before installation of the battery module and follow the instructions carefully during assembly. For any uncertainties, please contact Lithium Batteries SA for advice and clarification.
LBSA lithium iron phosphate (LifePO4) 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 application. The battery pack supports 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 cell information including voltage, current and temperature. What's more, the BMS can balance cells when charging and discharging to extend cycle life.
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 render it inoperable.

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 the charging process to ensure a reliable safety and performance. This capacity will be influenced by the temperature as the cells generally have less capacity available under very cold temperatures.

When connecting the batteries in parallel the batteries should be connected to a central busbar and from the busbar be distributed to the inverters with equal cable lengths. This unit is compatible with all LBSA SMART batteries. Terminals must not be torqued more than 6nm. M8 rawl bolts to be used to mount the wall bracket to a wall (please ensure that the surface/structure/wall is capable of carrying the unit weight.
Ensure a secure mounting surface that can support the weight of the battery. Use a 14mm/12mm drill bit (depending on a Rawl bolt of your choice) to drill two holes in the wall approximately 270mm apart. (use the bracket as a guide) Mount the bracket to the wall by using M6/M8 Rawl bolts. The mounting points of the bracket need to be flush against the wall. Once the bracket is secure you can screw your two mounting studs into the top middle Rivet nuts at the back of your battery. You must then slide your battery into the two central slots of your bracket.
| Questions | Answers |
|---|---|
| What are the DIP switch settings for one battery? | All DIP switches must be off when there is only one battery installed. |
| How many batteries can be connected in parallel? | The BMS in an LBSA battery can connect up to 16 units in parallel with full communication. However, there is no limit on the number of batteries that can be connected in parallel without communication as long as all wires are of equal length going to a central busbar. |
| What are the DIP switch settings for one battery? | All DIP switches must be off when there is only one battery installed. |
