No thanks -- I'm not going to build my own battery. My previous attempts at soldering have all ended up looking like abstract sculpture, and not in a good way. ;)
I might give it a try if I could assemble a battery using duct tape!
It sounds like I'd be better off with a built-in heater. I understand that it would not be strictly necessary to build an insulated battery box, since it's usually in the 25 degree range at night when we camp in the Sierra.
But why not build a cozy box and conserve energy? Is there a downside that I am missing?
