Jikong Technology's own bilingual (Chinese and English) product specification for the JK-B2A8S-30P active balance BMS board, version 19.0.1 (cover; the revision record on page 4 prints "2025.03.14 V19.0.1" as the first release), 26 pages. Its function selection guide (section 2.3, page 9) lists the JK-B2A8S-30P and six function options by their own model codes, row 7 being JK-B2A8S-30PHCR (standard + heating + CAN + RS485). Its other tables are headed JK-B2A8S-30P and name no option code. 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-B2A8S-30P-Product-specification.pdf (HTTP 200, final URL the same), on October 29, 2026 at 18:12:34.589 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.
