Battery Specifications

Physical Specifications

Inverter Compatibility

The SOK SK12V206H works with any LiFePO4-compatible charge controller and inverter-charger that accepts the standard 12V LiFePO4 charge profile (14.4-14.6V absorption for 12V / 28.8-29.2V for 24V). Confirmed compatible with:

• Victron Energy MultiPlus, BlueSolar, SmartSolar (no CAN — voltage-based monitoring only)
• Renogy DC-DC converters, MPPT charge controllers, and inverter-chargers
• Outback Power FX/FXR inverter-chargers
• Magnum Energy MS-PE inverter-chargers
• WFCO, Progressive Dynamics, IOTA RV converters (set to lithium mode)
• Most ABYC-compliant marine charging 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.

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 SK12V206H heater rating is sized for the 206Ah cell pack — typical heater current draw is well under 5A even in extreme cold.

Parallel & Series Configurations

Connect up to 10 SK12V206H units in parallel for larger capacity (2060Ah 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.
