Volthium 12V 400Ah Self-Heating Battery – ABS 8D Format

12V 400Ah Self-Heating Battery – ABS 8D Format

The Volthium 12V 400Ah ABS Self-Heating LiFePO4 battery in 8D format is purpose-built for boats, sailboats, motorized vehicles, RVs, and industrial applications. Featuring Grade A+ prismatic cells from the Volkswagen Group, a Texas Instruments BMS programmed by Volthium engineers in Québec, an integrated aluminum heatsink cooling system, and a self-heating system, it delivers reliable performance from -25°C discharge to -40°C recharge — outperforming the competition in every condition.

Key Features

• 4.8kWh energy capacity — 12V 400Ah LiFePO4 in a rugged ABS 8D form factor
• 250A continuous discharge (45 min) / 300A peak (3s) — high-output performance for demanding loads
• 2 RJ45 communication ports — MODBUS and CANbus compatible; ABYC E-13 compliant
• IP55 splash-resistant housing — built for marine and outdoor environments
• On/Off switch — disable discharge during storage while keeping charge active; eliminates parasitic drain
• Self-heating system — recharge down to -40°C; discharge down to -25°C (vs. -20°C for competition)
• Cold charging protection — engineered for Canadian climate conditions
• Integrated aluminum heatsink cooling system — draws heat away from cells via conductive plate; extends cell lifespan and increases usable temperature range
• Accessible BMS compartment — reserved access panel for easy servicing and repair
• Vibration-resistant construction — ideal for marine and mobile applications
• Smart Bridge compatible — add Bluetooth monitoring via the Volthium app; set SOC alerts, temperature warnings, and ABYC-compliant audible/visual alarms (Standard E-13)
• Grade A+ Volkswagen Group cells — automotive-grade prismatic cells for long-term performance
• Texas Instruments BMS — trusted by NASA and the U.S. military; fully programmed by Volthium engineers in Québec
• 6,000+ cycle lifespan — useful life of 15 years and beyond
• 10-year warranty
