SOK 12V 206Ah IP65 Lithium Battery with heater

SOK 12V 206Ah Heated LiFePO₄ Battery – Cold-Climate Ready for Kiwi Off-Grid, Motorhome and Backup Power

The SOK 206Ah 12V heated lithium battery is engineered for the one thing most lithium batteries quietly fail at: charging in the cold. With built-in self-heating tech that activates automatically below 0°C, this battery keeps performing through alpine winters, frosty South Island mornings, and shoulder-season trips when standard lithium packs simply shut down to protect themselves.

Inside the sealed enclosure you'll find genuine grade A prismatic LiFePO₄ cells paired with SOK's own custom-designed BMS — not the generic off-the-shelf board you'll find in most competitor batteries. It's purpose-built around SOK's cells and handles cell balancing, over-current, over-voltage, short-circuit, and temperature protection without you ever needing to think about it. The fully sealed case keeps moisture and dust out — a real consideration for campervans, remote bush cabins, and off-grid sheds where conditions aren't always kind to electronics. At around 23kg it's a fraction of the weight of an equivalent lead-acid bank, and the usable capacity is genuinely 100%, not the 50% you'd get from AGM.

SOK has been one of the most trusted names in the global DIY off-grid community for years, with a track record built on transparency, build quality, and batteries that actually do what the spec sheet says. We import directly from the factory and back every battery with a 7-year warranty, with realistic service life of 15+ years when looked after. If you're spending good money on a lithium setup, buy the one that won't let you down when the temperature drops.
