JK-PB2A16S20P
JK-PB2A16S20P
JK-PB2A16S20P is a 200 A-class energy-storage BMS for 7-16S Li-ion, 8-16S LiFePO4 or 14-16S LTO packs. V19.0.3 explicitly maps the 20P model to 200 A maximum continuous, charge and discharge current. V24.0.1 verifies 2 A active balancing, Bluetooth, CAN, dual RS485, a display interface, heating control, dry contacts, parallel current limiting and discharge precharge. Confirm the hardware revision, protocol and harness before ordering.

MANUAL-VERIFIED TECHNICAL REFERENCE
JK-PB2A16S20P data by hardware revision
The V19.0.3 manual explicitly maps JK-PB2A16S20P to the 200 A current tier, while V24.0.1 verifies the chemistry-specific cell counts, 2 A active balancing, standard interfaces and V24 enclosure. Match the hardware revision before wiring.
Electrical limits
Use the correct rating label
- Active balance
- 2 A
- Current class
- 200 A
- Supply voltage
- 20–80 V
V19.0.3 maps the 20P model to 200 A maximum continuous, charge and discharge current. For V24.0.1 hardware, keep 200 A as the model class and confirm the configured protection limits.
Interfaces and functions
Standard is not the same as optional
Standard
Bluetooth · CAN · RS485-1 · RS485-2 · display interface
Additional standard functions
Heating control · Two dry-contact outputs · Parallel current limiting · Discharge precharge
- CAN and RS485-1 are provided for inverter communication.
- RS485-2 is used for parallel communication or PC software.
- Protocol compatibility, cable pinout and inverter settings must be confirmed for the target system.
Mechanical and environment

- Operating temperature
- -40°C to 75°C
Revision control matters.
- V19.0.3 explicitly maps JK-PB2A16S-20P to 200 A maximum continuous, charge and discharge current.
- V24.0.1 lists 100 A, 150 A and 200 A tiers; confirm the shipped label and configured limits before relying on a protection setting.
- V19 and V24 wiring, connectors and harnesses must not be mixed by assumption.
- The available documents do not establish that V24 replaces every V19 unit.
- Weight, operating-power value and disputed instantaneous-current values are intentionally not published here pending final adjudication.

Before ordering
Four details that prevent the wrong configuration
- Photograph the product label or confirm the exact hardware/manual revision.
- Provide battery chemistry, series count and expected charge/discharge demand.
- Provide the inverter brand and model, required CAN or RS485 protocol, and parallel-pack plan.
- Confirm display, communication cable, heating, dry-contact and precharge requirements in the order.
