At 14.8V nominal, this pack matches the OEM battery voltage specification of the Yamaha Seawing II and Robosea Seaflyer exactly \u2014 eliminating the voltage convention ambiguity that arises with alternative packs rated at 14.4V nominal and the connector and BMS compatibility questions that follow. The 148Wh energy rating delivers sustained dual-motor continuous operation in the 800\u20131000W range, depth-rated to 50\u201360 meters with every production unit individually verified through two-stage waterproof testing before shipment.<\/p>\n<p data-start=\"3863\" data-end=\"4606\">The cell-level FUSE architecture differentiates this pack from standard BMS-only protection designs. In a sealed IP68 enclosure where venting is physically impossible, a hard short circuit at any individual cell creates a thermal propagation risk if the fault current path is not interrupted at source before the pack-level BMS can respond. Each cell in this pack carries an individual fusible link sized to open under the current spike of a hard cell-level short, cutting the fault at the cell before heat can transfer to adjacent cells. The Japanese-brand IC BMS layer then handles the full range of pack-level protection \u2014 overcharge, overdischarge, overcurrent, overtemperature, and short circuit \u2014 as a second independent protection tier.<\/p>\n<p data-start=\"4608\" data-end=\"5148\">OEM and ODM customization covers voltage, capacity, enclosure dimensions, declared waterproof depth, and connector type. The compact, lightweight form factor is designed for fast installation into fixed-chassis sea scooter platforms, with dimensional consistency maintained across production batches through first-article inspection at each run. Factory documentation includes IP68 pressure log records, immersion test photographs, and UN38.3 transport compliance certificates structured for downstream CE marking technical file submission.<\/p>","protected":false},"excerpt":{"rendered":"<ul>\n<li data-start=\"2166\" data-end=\"2345\">\n<p data-start=\"2168\" data-end=\"2345\"><strong data-start=\"2168\" data-end=\"2204\">IP68 rated to 50\u201360 meters depth<\/strong> \u2014 dual-barrier sealed enclosure;
