12V or 24V? Here's the short answer
Most people land here asking the same question, so here's the plain version.
Go 12V if you're upgrading an existing 12V setup in a van, caravan or small boat, or you're running an inverter of around 2kVA or less. Most of your lights, pumps, fridges and USB chargers already run on 12V, so it's the easy swap.
Go 24V if you're building a new system from scratch, running bigger loads like a larger inverter, or you've got long cable runs. Doubling the voltage halves the current, which means smaller cables, less heat and less power lost along the way.

Batteries that talk to your Victron system
Two batteries in the range, the SOK 12V 314Ah and the SOK 24V 150Ah, connect straight to a Victron Cerbo GX or other GX device.
That means the battery itself tells your system its real state of charge, and sets the charge limits for your inverter and solar chargers. No guessing voltages, no fiddling with charge profiles, and everything shows up in VRM so you can check on things from your phone, wherever you are.
If you're running Victron gear, or planning to, these are the two to look at first.

Putting it in a boat?
You want the Marine version. The SOK 24V 150Ah Marine is certified to AS/NZS 3004.2 for boat installations, with extra safety features built for life on the water.
See the Marine batteryWhy SOK, and why buy from us
Anyone can import a pallet of cells and put a sticker on them. What matters three years in, when something plays up, is whether there's a person in New Zealand who picks up the phone.
We're SOK's distributor for the Asia Pacific region. SOK design their own battery management systems and control their own manufacturing from start to finish, so the cells, the BMS and the build quality all come from one maker who stands behind them.
Every battery on this page carries a 7 year warranty, backed here in New Zealand. If something goes wrong, you're talking to us, not a support line in another time zone.

Usually, yes. Just check your charger and solar controller have a lithium or LiFePO4 setting. If they don't, it's worth upgrading them so you get the full life out of your battery. Ask us if you're not sure.
Yes, but use a DC to DC charger between the alternator and the battery. Lithium batteries can pull a lot of current, and a DC to DC charger protects both your alternator and your battery.
Yes, you can run batteries of the same model in parallel for more capacity. Mixing different models or old and new batteries isn't recommended. Get in touch and we'll help you work out the right setup.
It's better to buy a 24V battery. One battery with one management system is simpler, safer and easier to monitor than two batteries trying to work together.
For boat installations, go for the SOK 24V 150Ah Marine, which is certified to AS/NZS 3004.2. See the Marine battery
