The 48V 100Ah 5kWh IP68 underwater AUV battery pack operates at a depth envelope that eliminates the recreational and light-commercial dive equipment frame of reference entirely. Rated for continuous submersion from 1000 to 5000 meters, this pack is engineered for autonomous underwater vehicles, deep-sea inspection platforms, and subsea robotic systems where ambient pressure exceeds 100 bar and where recovery of a failed battery system is measured in days, not minutes. At 200A continuous discharge, the pack sustains 10kW motor loads across extended mission durations \u2014 the energy density and current delivery required for propulsion, payload operation, and onboard systems running simultaneously on a single battery architecture. Every production unit is individually verified through two-stage waterproof testing before shipment, with pressure log records and immersion documentation provided as standard with OEM orders.<\/p>\n

The cell architecture applies Tesla-process manufacturing standards to each cell in the pack \u2014 a production methodology that prioritizes cell uniformity, internal resistance consistency, and dimensional tolerance at the cell level before pack assembly begins. Every cell carries an individual fusible link sized to open under hard short-circuit current at that specific cell, interrupting the fault current path before heat can transfer to adjacent cells. In a pressure-rated enclosure at 5000 meters where ambient pressure exceeds 500 bar and where no venting path exists, cell-level fault isolation is not a performance feature \u2014 it is a fundamental safety architecture requirement. The Japanese-brand IC BMS operates as an independent second protection tier across all normal fault conditions.<\/p>\n

OEM and ODM customization covers voltage, capacity, declared waterproof depth across the 1000\u20135000 meter range, enclosure outer dimensions, connector type, and BMS communication protocol. The compact, lightweight design minimizes the buoyancy and weight budget consumed by the power system within the AUV or robot chassis. Factory documentation includes IP68 pressure log records, immersion test photographs, and UN38.3 transport compliance certificates structured for downstream regulatory and certification submissions.<\/p>","protected":false},"excerpt":{"rendered":"
