MODEL INDEX

Every stocked model code, with its ratings

Ratings differ between codes that read almost the same, so compare them here rather than across listing titles. Series range, continuous current, balance current and fitted ports for every JK-BD, JK-PB, JK-B1A and JK-B2A model held in stock.

Use this index before comparing copied product listings

Search results and marketplaces may show similar JKBMS, JK BMS, JK-BMS, and JIKONG BMS names. This page keeps the official product pages in one searchable index so buyers can confirm the exact model, product family, current rating, balancing class, and communication requirements.

Final compatibility still depends on battery chemistry, series count, inverter or charger protocol, firmware, wiring, and the selected accessories. For bulk purchases, verify the written quotation through the official contact channel.

ENGINEERING NOTES

Settle the decision, then pick the part

Each note works through one decision end to end. Where a note and a product page disagree, the product page and the written quotation are the ones that bind.
SOURCE CHECKS

Check a JKBMS source

Check a JKBMS listing against what a reseller cannot restate: the four segments of the model code, the version the board reports itself, the visible port set, and a quotation that names its own exclusions.

From brand name to part

All four spellings return the same hardware, so none of them narrows anything. This maps the term you searched to the artefact you were actually after: a model code, a manual, a firmware note or a cable.
