SOK 12V 314Ah Heated LiFePO₄ Battery – The Flagship 12V Battery for Serious Off-Grid, Tiny Home & Motorhomes
The SOK SK12V314PH is the most capable 12V battery we sell. With 314Ah of usable capacity, 4019Wh of energy, and a 200A continuous discharge rating, it's built for properly demanding installs — large off-grid homes, premium tiny home setups, and high-load systems where you need confidence that the battery can keep up. Built-in self-heating handles cold weather automatically, and the PC+ABS case is IP67 rated, so this is the SOK battery you can install in genuinely exposed locations without worrying about moisture, dust, or splash.
Inside, you get genuine grade A 314Ah prismatic LiFePO₄ cells with 3500+ cycle life, paired with SOK's own custom-designed BMS — purpose-built around SOK's cells rather than a generic off-the-shelf board. It supports Victron CAN bus communication out of the box, so your Cerbo GX or Multi can read state-of-charge, voltage, current, and temperature directly from the battery — no separate shunt or workaround needed. There's a built-in gas aerosol fire suppression system that activates automatically if things ever go wrong internally, an LCD SOC indicator on the lid, and a physical on/off switch for safe servicing or storage.
The SK12V314PH is certified to UL1973, UL9540A, IEC62619, and UN38.3 — so it'll satisfy installers, insurers, and shipping requirements without fuss. Wire up to 4 in series for 48V, or up to 10 in parallel for a properly sized house bank. SOK has been one of the most trusted names in the global off-grid community for years, with a reputation built on transparency, build quality, and batteries that actually do what the spec sheet says. We import direct from the factory and back every unit with our warranty, with a realistic 15+ year service life when looked after. If you want the best 12V lithium battery on the market, this is it.
