46.8V 28.6Ah 13S13P 18650 Lithium Battery Pack for Industrial Robots
Industrial robots work in challenging conditions where power stability, high peak current, and real-time battery management are essential for system safety and uptime. In this project, CMB developed a 46.8V(48v) 28.6Ah lithium-ion battery pack specifically for an industrial robot platform requiring high discharge capability, communication integration, and long service life.
Key features：
- Built in a 13S13P configuration using 169 individual 18650 cells (3.6V, 2200mAh each).
- 60A max discharging current, 120A Instant discharging current
- Stable 48V(46.8v) platform under continuous and peak load
- Intelligent BMS with RS232 & RS485 communication
- Full protection against electrical and thermal risks

13S13P 46.8V 28.6Ah 18650 Battery Pack FAQs
Why do industrial robots require a dedicated battery design instead of a standard 48V pack?
Industrial robots draw high and sudden currents during acceleration, lifting, and emergency stops. Standard battery packs often suffer from voltage drop, overheating, or early failure. This pack is designed with high parallel structure and controlled internal resistance to keep output stable.
Is the Battery Management System (BMS) fully implemented for smart robots?
Yes. The battery pack integrates a fully functional intelligent BMS, including:
Real-time voltage monitoring
Current and temperature protection
Cell balancing
Overcharge and over-discharge protection
Short-circuit and over-current protection
RS232 & RS485 communication support
Is this battery suitable for long-hour or multi-shift operation?
Yes. The battery is designed for continuous charging and discharging under high power demand. Its cycle life supports long-term industrial use and lowers replacement frequency.
