    Hi Jaime,

    Since you didn’t go into where you are going to put the new Lithium Batteries, let me share some of my experience. Although you can discharge them below freezing, you cannot charge them. If you insulated the battery box, it doesn’t take much to keep them above freezing, I use some 12 volt light bulbs that equal about 100 watts. My application is for an RV, but same principles apply.

    I am not very good at writing, but I did do some blog post.
