Overview
JIKONG P-Link-CR is a JKBMS serial BMS RS485 interface board designed to add an RS485 communication interface for compatible JIKONG (JK) BMS systems. Compatibility is not universal—verification is required before purchase.
Important compatibility notice: Before ordering, check that the BMS has an RS485 and CANBUS connector (4-pin). If the connector type does not match, the accessory will not be compatible. This product is an RS485 interface board and does not provide CANBUS function.
Key Features
- RS485 communication interface board for compatible JIKONG (JK) BMS.
- Compatibility check guidance: verify the BMS has a 4-pin RS485 and CANBUS connector.
- App-side protocol verification guidance: confirm protocol settings before use (see “Specifications” for the on-screen items and protocol list names).

Details

Verify your JK BMS has the matching 4‑pin RS485/CAN connector before ordering; connector mismatch means it will not fit.

Confirm the required UART protocol options are available in the JK BMS app settings prior to purchase and setup.



The interface board integrates inside compatible JK BMS hardware to provide an RS485 communication connection.

Port labels and pinouts help identify RS485 (default) versus headers that may require customization on some setups.





Use the model/spec table to confirm your BMS variant and its supported communication interface before selecting accessories.
