      Hi Mike,
       The insulation is a good thing I wish mine was especially in winter when I have the waterbed heater on, but ventilation would be a good thing too. While it is nothing like Pb, I do remember when my lithium were new that there was a little off gassing that is probably normal and annoying but in my case that was going into the cabin so I did use the fan for that but either I have gotten used to it or it has dissapated.
      Good luck with your project I am really pleased with my lithium and I only have a small pack but it serves me nearly every day and I have not plugged it in, in two years.
      Bouty

      Thanks Bouty,
      I'm just trying to get the box to not be so well insulated. I'm sure you are right. The car is charging at this time.

Going on three years on mine seem to realy like the warmer temps.If you look at the specs lithium has a much broader operating temperature range than Pb;  They do not heat up like Nimh and unless you are going to be driving for the entire capacity and charging right away and then driving again you are not even going to get close to being out of the limit. I never have and my summers are in the ninties for three months, I stopped using the manual fan except in winter to heat the pack.

That missing 485 pounds must be the heavy part in regards to spring rating. I installed the cells in a distribution pattern that is the same as the lead. 4 CALB cells weigh 28.5 lbs on my scale with the interconnects installed. The grp 27's weighed 68.5 pounds each.
