Yeah, so I decided the SLA tied together with a strap and layed on a sheet of cardboard needed something better. It's a shure bet it was gonna fail me eventually, and what about the cold?
So I chopped up the really thick packing box into a battery case,
with dual bottom layer. Routed the wires cleanly, too.
Then I sealed it shut using handyman's secret weapon. Lots of it.
Sealed that in a mostly water tight bag.
And put that into the carrying case. Voila!
