s-BMS is a battery management system (BMS) module developed by Lithium Balance, a technology company that specializes in the development of advanced sensing and control systems.

The distributed system s-BMS Battery Management System consists of a master board. The master board communicates with 32 Local Monitoring Units (LMU). 3-8 batteries can be connected to each LMU. The Local Monitoring Unit monitors the individual and total voltages of each cell and has 2 temperature sensors. It has applications up to 1000 v.

The s-BMS Battery Management System can be configured via the licensed s-BMS PRO software. This enables the battery integrator to create a unique design.

Application Software

  • Configuration Software: The s-BMS PRO software allows the battery designer to adjust the BMS configuration for their specific application and selected battery chemistry.
  • Service Software: The s-BMS SERVICE software provides secure after-sales service for the battery by giving users read-only access.
  • USB/RS232: Both s-BMS SERVICE and s-BMS PRO software require an adapter for connection from the BMS to the PC. The USB/RS232 adapter is optimized for s-BMS PRO/SERVICE.


LiTHIUM BALANCE offers a range of both air-cooled and water-cooled chargers. The chargers are available in capacities of 1.8 kW, 3.3 kW and 6.6 kW.

Wire Harness

  • Cell Monitoring Wire Harness: Custom-made cell monitoring cable assemblies and temperature cable assemblies can be provided for all s-BMS products.
  • Internal communication wire: A set of standard length interconnection cables are provided for all s-BMS products. The connection cables are manufactured according to the RS485 protocol.
  • External communication wire: For all s-BMS products there is a range of different I/O cables for connection to shunts, VCUs, relays, CAN devices and other peripherals.

Current Measurment

Shunt: A range of standard, compact and high precision shunts for all s-BMS products is offered by LiBAL. These shunts are also available to suit currents specific to almost any application.

Li-On Cells

LiTHIUM BALANCE offers a range of cost-effective cells. These products have proven themselves in the market for over 10 years. These cells are managed by BMS and also come with the possibility of an extended warranty.

Other Accessories

  • Fuses:  Fuses are another layer of safety for battery systems. LiTHIUM BALANCE also offers various fuses with suitable values for large format batteries.
  • Displays: LiTHIUM BALANCE offers a range of standard displays (CAN-based) that can be seamlessly connected to the s-BMS.
  • Relays: A range of standard and robust relays is offered for all s-BMS products. In addition, these relays can be selected to suit current and voltage levels specific to almost any application.


Application Support: We offer application support to ensure smooth integration of s-BMS into the system. The software license includes 5 hours of free support. However, other application support is provided on an hourly basis.

Training: s-BMS includes a comprehensive introduction to Li-ion technology and battery integration possibilities. LiTHIUM BALANCE has tailored its trainings specifically to user needs.

Remote surveillance: A modem-based surveillance system for s-BMS is connected to the BMS via CAN. The data is stored on a secure server and can be accessed from anywhere.
