Volthium 12V 314Ah PLUS Battery – Group 8D

12V 314Ah PLUS Battery – Group 8D

The Volthium 12V 314Ah PLUS is a next-generation LiFePO4 battery packed into a standard Group 8D enclosure — delivering 2× more usable energy and 2× less weight than a lead-acid battery of the same size. Equipped with SafeCharge™ technology, dual self-heating with smart thermostat, integrated Bluetooth, active cell balancing, and IP67 certification, it’s engineered for maximum autonomy with minimum complexity across marine, RV, and industrial applications.

Key Features

• 3.77kWh energy capacity — 12V 314Ah LiFePO4 in a standard Group 8D form factor
• 150A continuous discharge — 160A for 10 minutes, 500A for 3 seconds peak
• 150A charge current — ultra-high-performance BMS with active cell balancing
• SafeCharge™ compatible — safe direct alternator charging without complex wiring modifications
• Dual self-heating system — base heating + integrated smart thermostat; automatically redirects charger current to heating elements below safe operating temperature, then thermostat maintains ideal range for extreme climate reliability
• IP67 rated — dust-tight and immersion-resistant
• Integrated Bluetooth — monitor battery data directly from your device
• LED state-of-charge indicator — instant SOC visibility
• On/Off switch — disable discharge during storage while keeping charge active
• 2× M12 10-pin communication ports — CAN Bus and RS485 for system integration; ABYC E-13 compliant
• High reserve capacity — maximizes autonomy without multiplying battery count
• 2× more usable energy than lead-acid of the same group size — 2× lighter, faster charging, no capacity degradation over time
• Active cell balancing — protection against overcharge, over-discharge, and overcurrent
• 6,000+ cycle lifespan — useful life exceeding 15 years
• 10-year limited warranty
