I'm also wondering when Brood will have some more 4200 cells in? Carpet season is starting up around here and I am needing some cells. I ordered some of their 3800 cells a couple winters ago (last time I did electric racing) and was very happy with them.
Another question. For the IB4200 you charge them without any type of fan on them, correct? Also, how do you store them from week to week? Charged, partially charged, or empty?
