Heyo!
You can leave the battery on the 12v LFP mode for winter storage. You can also disconnect the battery from the vehicle and let it sit for the winter, and then when you want to use it again in the spring, you just need to make sure that the battery is recharged entirely with the charger before using it in the car.

Like Austen stated, Charge it up fully and disconnect from the car or unit until needed in Spring.
Thank You,
