Jikong Technology's own bilingual (Chinese and English) product specification for the JK-B1A8S-10P active balance BMS board, version 15.3.3 (cover; the revision record on page 4 prints V15.3.1 on 2024.03.21, V15.3.2 on 2024.06.12 and V15.3.3 on 2024.08.07, the last two for product outline drawing changes), 26 pages. It covers the JK-B1A8S-10P only; the JK-B1A8S-10PS has its own specification. The version is the document's; it is not stated to be a hardware version. Alternative Research obtained it with the paced research fetcher (robots.txt read on every hop; no browser, login or alternate client) from Jikong's own host, https://www.jkbms.com/wp-content/uploads/2026/02/JK-B1A8S-10P-Product-specification-15.3.3.pdf (HTTP 200, final URL the same), on October 29, 2026 at 18:12:48.704 UTC; it is linked from the Specifications list of jkbms.com's support page. The document prints no limit on copies. Manufacturer claims, not independent tests.
