I just compared the zippy flightmax 30C batteries. A 3300mah 6s weighs 544g and a 5000mah 4s weighs 527g so that kinda blows your theory that a 6s pack is lighter
Yes my mistake, but I trying a new batt Acorn racing. It's lighter. But must see how's the cost.
Zippy 4s 5000 is one of the heaviest in the market.
