Choose the file by board label
- Read the complete model code. Include the family, series, current suffix and any letters after it.
- Check the hardware or document revision. A version in a PDF filename does not prove the drawing page identifies your board; an unmarked older drawing needs an extra check.
- Confirm the physical connectors. If the printed label, harness or port positions differ from the PDF, stop and ask JKBMS support for the matching file.
Isolate the battery and follow the approved service procedure before handling sense leads or power cables. A generic inverter drawing cannot replace the board's cell-harness diagram.
FILED TOGETHER AS V21.0.1
JK-B1A8S-10P document set V21.0.1
The manual cover identifies JK-B1A8S-10P Version 21.0.1. The companion wiring PDF is filed under the same model and version, but its image page lacks a visible model or version title. Compare the board and harness with both documents before wiring.

JK-B1A8S-10P Wiring Diagram V21.0.1
The library filename ties this image-based PDF to V21.0.1, but the diagram page itself has no visible model or revision title. Verify the board and harness before use.

JK-QB2A8S-20P Active Balancer Protection Board Manual V17.0.2
Includes a wiring section in the V17.0.2 document for JK-QB2A8S-20P. Confirm the hardware before use; it is not a diagram for another QB or PB model.

Legacy model drawings
Some legacy PDFs with different model names contain the same generic diagrams. A filename alone does not verify a model-specific drawing. Treat the file below as a historical reference until JKBMS confirms the board and applicable revision.

JK-WBD6A24S-15P Wiring Diagram
The filename names JK-WBD6A24S-15P, but the drawing does not establish which hardware revision it fits. Confirm applicability with support.

SYSTEM TOPOLOGY
Inverter wiring is a separate reference
Inverter Wiring Diagram
This generic PDF shows inverter connection topology. Its file name gives no BMS model or hardware revision, so it cannot establish cell-sense, power-terminal or communication-pin wiring for a specific board.
For inverter communication settings and cable choices, see the inverter and BMS communication guide. Confirm the inverter model, BMS model and protocol before connecting the cable.
Looking for JK-PB2A16S-20P?
The available JK-PB2A16S-20P V19.31 firmware is software for the board. Its version does not identify a wiring diagram or prove that another JK-PB drawing matches your hardware. Request the correct wiring file with a clear photo of the full product label and connectors.
