A partner-linked copy of an ARCO document, not ARCO's own file: ARCO Marine's spec sheet for the A115/3500W-24V (parts 4412 and 4413), printed "DATA-003 REV-A 2/25/2026", served from productimageserver.com and linked from LFP Experts' A115 J180 Mount listing; captured October 29, 2026. No ARCO-hosted copy was found on ARCO's A115 page, Zeus collection or support documents page. Attached for reference only: the records' figures come from ARCO's own A115 page.

ARCO Marine's own store page for the ARCO Zeus A115/3500W-24V HD High Output Alternator, captured October 29, 2026 from the link on ARCO's Zeus High Energy Products collection: the description, the "Technical Specifications" table and the "SKU Details" line "Part # 4412: 24V J180 Mount | Part # 4413: 24V Pad Mount". One specification table covers both part numbers. The page address still reads a220-24v-hd; the page itself prints A115 and nothing on it ties the A115 to an earlier A220 product, so no history is taken from the address. Manufacturer claims, not independent tests.
