OFFICIAL JKBMS COMPARISON

Compare JK-BD, JK-PB, JK-B1A, and JK-B2A BMS models

Compare official JKBMS models by battery strings, documented current, active balancing, CAN or RS485, manual status, and intended battery application.

Series comparison

JK-BD Series

JK-BD Series

Higher-series lithium battery packs where current rating, active balancing, Bluetooth/display, and wired communication must be matched to the pack.

Confirm exact series range, current, balance current, display, harness, and application requirements.

JK-PB Series

JK-PB Series

Inverter-connected storage batteries where CAN or RS485 communication, display, and protocol checks are important.

Confirm inverter model, protocol, cable, firmware, battery voltage, and parallel requirements.

JK-B1A Series

JK-B1A Series

Compact lithium packs that need smart protection, app monitoring, and 1A-class active balancing.

Confirm current rating, cell count, chemistry, balancing needs, and installation space.

JK-B2A Series

JK-B2A Series

Lithium packs that need stronger 2A-class active balancing together with smart BMS protection.

Confirm whether stronger balancing is actually needed and still match current, wiring, and thermal conditions.
