Now with the updated V8 BMS they can be connected in series.

However with series connection you need a battery voltage balance. This one from Victron is recommended.

Does the SOK battery have low-temperature protection?
Yes. The BMS inside the battery will prevent charging below 0°C in order to protect the cells. It will allow the battery to discharge in freezing temperatures. If you need to charge the battery in freezing temperatures then we recommend the heated versions.

Can I store these SOK batteries in the cold?
The lowest safe storage temperature is -6°C. For any temperatures below this, you should bring them inside or add a heating pad of some sort. If a heating pad runs out of power and the battery falls below -6°C, damage may occur.

Do the SOK batteries fit into a standard "group size" battery box?
No they are likely too big to fit into standard boxes. Many people put them in tool boxes or any enclosed unit that protects them from the elements. The metal case units are not fully waterproof while the plastic case (marine version) are 100% waterproof.

Can I use any charger on the SOK batteries?
The batteries have a 7 year manufacturer warranty. If you are having issues with the battery we are here to help. In the rare case of a warranty claim we will ship you a new battery and deal with the claim with SOK. The 7-year warranty covers anything that fails or doesn't stand up to the manufacturers' specs, and includes both the cells inside and the BMS.

Great Batteries and customer support

I purchased 2 of these batteries and they were shipped very quickly to Calgary. I initially had several problems getting the batteries sync'd and charging properly etc. Taylor was very helpful and provided several suggestions which in the end resolved the problems and he even reached out a few weeks after our last communication to confirm that the batteries were charging as expected. Amazing customer service!!
