When your lithium battery pack powers an e-bike, robot, or electric skateboard, uncontrolled charging, deep discharge, excess current, and cell voltage differences can affect safety and service life. A reliable Li-ion BMS helps you monitor and protect the battery pack during daily operation. MAXKGO’s 8S-14S 30A BMS protection board supports 8S, 10S, 12S, and 14S Li-ion configurations, with a rated system range of 24V-48V. It combines overcharge, over-discharge, over-current, short-circuit, temperature protection, and cell balancing in a compact 47.6 × 32 × 9.2 mm PCB.
What Is a Li-ion BMS Protection Board?
A Li-ion BMS manages key electrical conditions inside a multi-cell lithium-ion battery pack. For you as a battery designer or system integrator, the BMS provides protection functions that help keep cells within defined operating conditions.
The MAXKGO board is a hardware BMS designed for Li-ion battery packs. It supports:
- 8S, 10S, 12S, and 14S configurations
- 24V-48V rated battery systems
- Up to 30A continuous discharge current
- Charging current of ≤10A
- 42 ± 5mA cell balancing current
- Common-port charging and discharging
- Working consumption below 35μA
- Sleep-mode consumption below 10μA
This configuration makes the board suitable when you need a compact Li-ion battery protection board without wireless communication or app-based monitoring.
Key Li-ion BMS Protection Functions
Overcharge and Over-Discharge Protection
The BMS monitors battery voltage and responds when the pack reaches its defined protection conditions. This helps you reduce the risk associated with excessive charging or deep discharge during normal battery operation.
30A Over-Current Protection
The board provides 30A continuous discharge capability, with an over-current protection value listed at 50 ± 8A. This makes the product suitable for medium-current battery systems where compact hardware protection is required.
Cell Balancing
Cell voltage differences can increase as a multi-cell pack operates and ages. The integrated balancing function provides a 42 ± 5mA balance current, helping maintain better voltage consistency between cells.
Short-Circuit and Temperature Protection
The protection circuit also responds to external short circuits, with a stated detection delay of 300μs. Temperature protection is specified at 55°C, with recovery conditions defined by the product parameters.
8S, 10S, 12S and 14S Li-ion BMS Comparison
Choosing the correct series configuration is important because your battery pack voltage depends on the number of Li-ion cells connected in series. MAXKGO supports four configurations on this board.
| Configuration | Typical Nominal System Class | MAXKGO Support | Key Use Consideration |
|---|---|---|---|
| 8S BMS | 24V class | Yes | Compact mobility battery packs |
| 10S BMS | 36V class | Yes | E-bike and light electric mobility |
| 12S BMS | 44V class | Yes | Higher-voltage mobility and robotics |
| 14S BMS | 48V class | Yes | 48V-class battery applications |
Actual pack voltage depends on cell chemistry, cell voltage, charging conditions, and the complete battery design. You should therefore confirm the cell specification and electrical requirements before selecting the BMS.
How to Select a 30A Li-ion BMS
You can follow these steps when evaluating a BMS for a custom battery pack:
- Confirm the cell chemistry. This MAXKGO model is specified for Li-ion batteries.
- Calculate the series configuration. Select 8S, 10S, 12S, or 14S according to your battery design.
- Check current requirements. The board supports 30A continuous discharge and ≤10A charging current.
- Review protection functions. Confirm overcharge, over-discharge, over-current, short-circuit, temperature, and balancing requirements.
- Check physical integration. The PCB measures 47.6 × 32 × 9.2 mm and weighs 13.3g.
- Confirm the wiring and accessories. The package includes HY2.0 7P and 8P cables.
