Inverter BMS Specifications — JK-PB2A16S20P V19

The following specifications apply to the kit options supplied with the JK-PB2A16S20P V19 Inverter BMS. Empty Box options do not include a BMS or LCD. Battery cells are not included.

• Battery configuration: 16S LiFePO4, 51.2V nominal system voltage.
• Continuous charge current: 200A.
• Continuous discharge current: 200A.
• Active balancing current: 2A.
• Inverter communication: CAN and RS485. Inverter protocol compatibility must be checked for the specific inverter model.
• Bluetooth: Battery monitoring and configuration.
• LCD connection: PB-compatible TTL-P display connection on the BMS main board. The UART/display ports are for the display, not for PC connection.
• PC connection: USB-RS485 cable connected to the RS485 port on the interface board.
• Maximum parallel operation: Up to 16 complete battery systems in parallel.

Expandable System — Maximum 16 Sets in Parallel

Supports a maximum of 16 sets in parallel, not 32. Parallel operation expands system capacity while maintaining the nominal 51.2V system voltage. The 16-set specification applies to complete battery systems equipped with the BMS, not to empty enclosures alone.

Key Specifications:

• Nominal Voltage: 51.2V

• Dimensions LMH: 472*750*270MM

• Enclosure Weight: Only 22.2 kg (without batteries) – easy to handle and assemble
