JBD Smart BMS 10S-17S 40A for NMC (SP17S005)

JBD Smart BMS 10S–17S 40A for Lithium-ion / NMC Battery Packs

The JBD Smart BMS 10S–17S 40A is an intelligent Battery Management System engineered to safely manage and protect lithium-ion or NMC battery packs ranging from 10 series (36V nominal) up to 17 series (61.2V nominal) configurations.

Designed for medium-power battery systems, this smart BMS ensures safe charging, controlled discharging, accurate cell monitoring, and effective voltage balancing. It is ideal for electric mobility, solar energy storage, portable power systems, and custom lithium battery builds.

🔧 Battery & Current Capability

This smart BMS supports:

• 10S–17S Li-ion / NMC battery packs
• Nominal voltage range: approximately 36V–61.2V
• 40A continuous discharge current, suitable for moderate power loads such as e-bikes, scooters, and small solar systems
• Up to 40A continuous charging current (depending on pack configuration and wiring quality)

It is built for reliable performance in everyday EV and energy storage applications.

🛡️ Advanced Protection System

The JBD Smart BMS includes a comprehensive safety suite to protect your battery and connected equipment:

• Over-charge protection
• Over-discharge protection
• Over-current protection
