The SOK SK12V314PH delivers genuine LiFePO4 chemistry, 314Ah of usable capacity, and the engineering trust signals that matter for Victron-based RV, marine, and off-grid solar systems. Built around a plastic (marine grade abs, ip67) for IP67 waterproofing, paired with a built-in self-heating pad for charging in temperatures down to -4°F, Bluetooth BMS monitoring, and a 7-year limited warranty. Direct CAN-bus communication with Victron Cerbo GX, MultiPlus, and Quattro inverters means real-time state-of-charge, voltage, and current data flows directly into your Victron system — no estimation, no drift, no manual SOC corrections.

Battery Specifications

Physical Specifications

Inverter Compatibility

The SOK SK12V314PH is purpose-built for Victron Energy systems. The CAN-bus communication port pairs natively with the Victron MultiPlus, Quattro, EasySolar, and Cerbo GX ecosystem at Urban Supply Inc. Real-time data exchange — voltage, current, state of charge, temperature, cycle count — flows directly into the Victron VRM portal and remote console. NMEA 2000 protocol support extends compatibility into marine systems with Garmin, Raymarine, Simrad, and Furuno chartplotters.

Also compatible with standard charge controllers and inverters from Renogy, Outback, MPP Solar, Magnum Energy, Schneider Electric, and any inverter accepting LiFePO4 charge profiles (14.4-14.6V absorption / 13.5-13.8V float for 12V systems).

Smart Features

Bluetooth BMS: Pair with the ABC-BMS app (iOS + Android) for real-time monitoring of cell voltages, state of charge, current, temperature, and cycle count.

Victron CAN-bus: Direct integration with Cerbo GX, MultiPlus, and Quattro inverters via the dedicated CAN port. Battery becomes a first-class citizen in Victron VRM with no separate shunt or monitor required.

Smart cell balancing: Active top-balance balancing keeps all cells within tight voltage tolerance throughout the charge cycle, extending overall pack lifespan and capacity.

Self-Heating Specs

The built-in heater pad activates automatically when the cell temperature drops below the safe charging threshold (32°F / 0°C). Power for the heater is drawn from the charger or solar input — not from the battery cells — so cold-weather charging does not drain stored capacity. The battery can safely accept charge at ambient temperatures down to -4°F (-20°C).

The SK12V314PH heater rating is sized for the 314Ah cell pack — typical heater current draw is well under 5A even in extreme cold.

Parallel & Series Configurations

Connect up to 10 SK12V314PH units in parallel for larger capacity (3140Ah max parallel bank @ 12V). Series connections support up to 4 units in series for higher-voltage banks (48V max series). For mixed parallel+series banks, follow the SOK installation manual — all batteries must be at the same state-of-charge before initial series connection.
