RE: Whats a good lipo charger/balancer for my efirestorm?
Hard cased packs were done for racers. If your not racing don't worry about them. As for the C rating it means the pack can handle a higher amp draw. But in a set-up like yours a higher c rated pack will run cooler and more efficient. And with that charger your charge times should be around 80 to 90 minutes.
