JKBMS RS485 Converter Module for 17S/20S/24S High Voltage Smart BMS — PC Monitoring & Parameter Configuration

JKBMS RS485 Converter Module for 17S/20S/24S High Voltage Smart BMS

The JKBMS RS485 Converter Module for 17S/20S/24S enables wired RS485 communication between your JKBMS Smart BMS and a PC or external devices. Connect it directly to the RS485 port on your BMS protection board to monitor real-time battery parameters and configure BMS settings via the free JKBMS PC software.

Designed for high voltage 17S/20S/24S battery systems (typically 48V–72V and above), this module is the essential communication accessory for JKBMS B series and BD series high voltage protection boards.

⚠️ For low voltage 4S–8S systems, please use the JKBMS RS485 Converter for 8 String instead.

Key Features

• ✅ Wired RS485 communication — stable and reliable data transmission
• ✅ Direct plug-in connection to BMS RS485 port via cable interface
• ✅ Monitor real-time battery parameters via JKBMS PC software
• ✅ Configure BMS protection parameters and settings
• ✅ Supports inverter RS485 communication (inverter must support RS485 protocol)
• ✅ Supports RS485-protocol displays (note: standard LCD displays connect via UART port, not RS485)
• ✅ Compact design — easy to install in battery enclosures

Compatibility

• ✅ JKBMS B series Smart BMS: 17S/20S/24S models (high voltage)
• ✅ JKBMS BD series Smart BMS: 17S/20S/24S models (high voltage)
• ❌ Not compatible with JK-PB Inverter BMS series
• ❌ Not compatible with 4S–8S low voltage models (use RS485 for 8 String instead)

Communication Interface Notes

• PC monitoring & configuration: connect via RS485 to PC using this module
• Inverter communication: supported via RS485 (inverter must support RS485 BMS protocol). CAN connection is recommended where available for more stable inverter integration.
• Display connection: RS485-protocol displays are supported. Note that standard JKBMS LCD displays connect via the UART port, not RS485.
