Product Description
13S 25A Li-ion BMS – JLS-B-Z13S-510-V0
High-Power, High-Safety Battery Management System for 48V Applications
Overview
The JLS-B-Z13S-510-V0 is a high-reliability, 13-string lithium-ion battery management system (BMS) engineered for 3.6V ternary (NMC) battery packs. Designed for demanding applications such as e-mobility, energy storage, and industrial equipment, this BMS ensures stable 25A continuous discharge while providing comprehensive protection against electrical and thermal faults.
Built with automated SMT assembly and premium components from Sinowealth (IC) and JieJie Micro (MOSFETs), it delivers low internal resistance (<30mΩ) and ultra-low standby power consumption (<150µA).
Key Features & Benefits
Feature | Benefit |

Temperature Protection:
Discharge: -20°C to 75°C
Charge: 0°C to 50°C
MOS High-Temp Protection (Auto recovery)
Recovery: Automatic recovery after fault removal (load/charger disconnect).
Ideal Applications
Perfect for OEMs and DIY builders requiring robust power management:
Light Electric Vehicles: E-scooters, e-bikes, balance cars.
Power Tools: High-drain cordless equipment.
Energy Storage: Home backup batteries, solar storage systems.
Robotics & Drones: UAV power systems requiring high discharge rates.
Medical Devices: Portable diagnostic equipment.
Why Choose Us?
As a leading PCB & PCBA manufacturer, we don't just sell BMS boards—we provide manufacturing assurance:
Strict DFM Standards: Every BMS is produced using automated SPI/AOI inspection to eliminate soldering defects.
Component Integrity: We use branded MOSFETs (JieJie Micro) and ICs (Sinowealth) exclusively. No counterfeit parts.
Fast Prototyping: Need a custom configuration? We offer rapid sampling and mass production.
Frequently Asked Questions (FAQ)
Q: Is this BMS suitable for LiFePO4 (LFP) batteries?
A: No. This specific model (V0) is calibrated for 3.6V/3.7V Ternary (NMC) chemistry. Using it with LFP (3.2V) will result in incorrect cut-off voltages. Contact us for an LFP version.
Q: How do I connect the BMS to my battery pack?
A: Please follow the strict sequence in the datasheet: Connect B- first, then B+, then the cell sense wires (ribbon cable). Incorrect wiring will damage the board.
Q: Can I get a custom version with CAN bus or Bluetooth?
A: Yes. As a factory, we support customization. Contact our sales team to discuss your requirements for communication protocols (CAN/RS485/Bluetooth) or specific current ratings.
