How do you charge the gel cells?  If I remember the ones in Georgia, there
were binding posts on the outside of the ammo cases that I assume go to the
gel cell battery terminals.  Are there charge controllers built into the box?  
If so, what kind/where do you get them?  If not, what external charge 
controller do you use?

Also, for those who use ammo cases, have you ever had overheating problems?
It can get really hot in Texas, and I wonder if anything goes wrong with
gear when it gets really hot...
