By the way, if anyone is feeling entrepeneurial (I think that is how it is spelled), there is a need for a sturdy insulated Lithium-compatible battery box that can be mounted on the tongue of a trailer. I have done a fairly good Google search (more than ten minutes!) and have come up empty.
Most of the commercially available boxes are vented, which is not needed for lithium and which defeats the built-in heater that would be needed for cold weather operation.
And in addition to designing and marketing the box, why not come up with an external add-on heater that would go into the box? I think Ultraheat has something that would do the job, with a little modification. If that works, you would not need a high end battery with a built-in heater -- just the box and the external heater.
Almost every problem is a business opportunity! (But not for me -- I'm retired.)
