HARDWARE, ACCESSORIES AND UPGRADES

Turn the technical file into a compatible hardware plan

Use the manual or firmware to identify the exact product first, then continue to the matching BMS, display, cable or factory-assisted upgrade.

Compatibility first. Confirm the exact model, hardware revision, connector, protocol and firmware before ordering. A similar product name does not guarantee compatibility.

Ask JKBMS to verify

MONITORING, UPGRADES AND ACCESSORIES

Add monitoring, raise current or replace the board

Published prices for the parts owners add most often, taken from the live catalogue on this site. Confirm the model, hardware revision and port before ordering.
