When deciding on what type of battery you need, we can assure you that a SOK is the best lithium battery Canada has to offer. Lighter and longer-lasting than older counterparts, these are the best bang for your buck whether you are trying to power your RV, van, boat, cabin, or off-grid living. 

Easy to plug in and forget, SOK batteries keep you worry-free with advanced management systems that protect them from all elements and issues. 

The marine versions of these awesome lithium batteries are useful in many applications too, not just for those with boats! Made to withstand the weather, consider these as ideal for locales often exposed to the elements, like a winter ski cabin, houseboat, or maybe even an ice fishing camp? The applications are endless, and if you aren’t a full-time van lifer, why not get dual use out of your equipment?
