The LiFePO4 prismatic cells in all SOK batteries are a genuine Grade A product that will provide most users with a usable lifespan of up to and possibly beyond 20 years.
SOK batteries are renowned for their high-quality construction. The cells, BMS, wiring, and busbars are all thoughtfully designed and integrated, resulting in a battery that is not only safer but also more reliable and durable. Which SOK battery is right for you?
Every SOK battery uses the same Grade A LiFePO4 cells and smart BMS, so the choice really comes down to how much power you need and where you'll be charging it.
- 100Ah — the everyday choice for weekend campervans, smaller caravans, and boats running lights, a water pump, and device charging. Plenty for a couple of nights off-grid between charges.
- 206Ah–280Ah — step up here if you live in your rig full-time, run a compressor fridge around the clock, or power an inverter for the kettle, coffee machine, or induction cooktop.
- 314Ah — the big house bank for off-grid baches, tiny homes, and anyone wanting to go days between charges. This model also adds Victron communications, so it talks directly to a Cerbo GX or other Victron system.
Heated or not? LiFePO4 can't safely charge below 0°C. If you'll be charging in the cold — South Island winters, alpine trips, frosty mornings — pick a Heated model and the built-in heater handles it automatically. If you only ever charge in mild conditions, a standard IP65 model is all you need.

We recommend a Victron battery balancer to protect your battery. IMPORTANT:
Batteries are shipped at 30% SOC, so you need to fully charge it when you get it before running anything. Instructions / LiFePO4 Settings (12 Volt):
