Interfaces & Port Notes
- RS485 (by default): GND, RX, TX, VCC
- CANBUS (need customization): GND, CAN_H, CAN_L
- LCD (by default): K-, K+, GND, B, A, VCC
- Heat function (need customization)
Operating Modes (as described)
- Storage Mode: for transportation/storage/offline or wireless transmission off mode; does not consume battery pack current
- Normal Working Mode: when the charger is inserted in storage mode/off mode, the BMS returns to normal working mode; protection, equalization, and communication functions return to normal working
- Standby Mode: in static state (no charge/discharge current and no equilibrium current), the BMS enters standby after the set time (1-30 days can be set)
- Shutdown: automatic shutdown voltage; shuts down when a cell falls below the shutdown voltage (intended to prevent long-term power waste and battery pack damage)

Details
Built on the JK smart BMS platform, active balancing helps keep series cells closer in voltage for more consistent pack performance.
Multiple series configurations and interface options are available across the JKBMS range; select the version that matches your battery chemistry and string count.
A compact enclosure and multi-connector layout make it easier to route balance leads and communication wiring during installation.
Connection headers provide paths for RS485 by default, with CANBUS and heating-function support available on compatible versions.
Bluetooth monitoring on iOS/Android lets you check pack voltage, current, and per-cell readings directly from the app.
Layered protection features help safeguard the battery pack against common fault conditions such as over-charge, short-circuit, and over-temperature.
Smart operating modes reduce idle drain by switching between storage, standby, and shutdown behavior based on pack state.
Use the specification chart to confirm supported series strings, balancing current, and communication interfaces before ordering.
