400V 1000V 460Ah 4600Ah DNV Liquid Cooling Preheating 38.4V IP67 LiFePO4 Marine Battery System

Built to meet strict DNV classification standards, the battery system integrates a multi-layer Battery Management System (BMS) for real-time monitoring of voltage, temperature, and system health. Advanced safety features include anti-propagation design, aerosol fire suppression, and an integrated off-gas ventilation duct system to ensure maximum safety even in extreme conditions.

With liquid cooling, IP67-rated modules, and over 3500 charge cycles at 80% depth of discharge, the W-DNV107 delivers exceptional durability and efficiency. Its modular rack design allows easy installation, maintenance, and system expansion, while remote diagnostics and software updates via MSCU provide intelligent control and reduced operational costs
