    Battery pack made from several small modem packs.

    What if i only draw max 30amp for several secs but keep my constant current to 15amp or below would building the pack with a 9cells in parallel or 12cells in parallel be ok? Also suppose I keep a fan in the battery pack to keep them constantly cool would that be a good idea? Or better yet...
