The MarinePro 84V 15A Lead Acid Battery Charger redefines rugged power delivery for marine and electric mobility applications. Featuring a milled 6063-T5 aluminum chassis with IP65 protection, this third-generation charger ("3" marked variant) integrates an enhanced cooling system combining helical finned heatsinks and a 9-blade axial fan, achieving 25% thermal improvement over previous models.

Our proprietary SmartCharge 4.0 technology employs microprocessor-controlled adaptive charging, automatically optimizing parameters for LiFePO4 (102.2V CV) and lead-acid batteries (102.9V CV). The four-stage charging algorithm ensures complete charge cycles while preventing sulfation or lithium plating, supported by real-time thermal monitoring via dual ball-bearing fans.

Key Innovations Include:
• Multi-Protocol Support: Compatible with SAE J1772 and IEC 60309-2 marine charging standards
• Shock/Vibration Resistance: MIL-STD-810G certified mounting brackets withstand 5G vibrations
• Smart Grid Interaction:** PFC-corrected input (0.99 PF) minimizes harmonic distortion

The compact 310mm-length design incorporates M8-threaded mounts for vertical/horizontal installation in engine compartments or charging stations. Dual Anderson SB175 connectors enable parallel charging at 30A total current, while the diagnostic LED array provides instant status updates - critical for offshore operations.

Tested across 1,200+ charge cycles and 50,000-hour MTBF validation, this charger delivers unmatched reliability in tidal zones (-40°C cold starts) or tropical environments (+85°C surface tolerance). Optional RS-485 connectivity allows fleet operators to monitor charging health via Modbus RTU protocols.

With its sandblasted oxidation finish (Ra ≤3.2μm) and tool-free maintenance access, the MarinePro series represents the new benchmark in maritime electrification. Each unit ships with a 3-year waterproof warranty and IECEx certification for hazardous area deployments.
