which of the above reasons do you have for needing to cool the pack?
keep in mind that any cooling system will make the pack less efficient--eitehr it takes more space than it would with out it, or more weight, or more power if it's an active system.
ifspace is the reason,then the extra cells you would add to lessen the heat problem might take less space than the cooling system.
when it comes to searches, you have to think about what words people might have used together in the actual post, because the forum doesn't have the ability to find threads based on what they might be about, only on the actual words in them.
using * as a wildcard for things helps, too.
cool* finds cooling, cooled, cooler, coolest, etc.
batter* finds battery batteries etc
the less words you enter the more it will find.
