Connecting Two 3S Batteries in Series to Make a 6S Battery for $54 bucks!

In the video I stupidly forgot to add a zero to the weights. I wish the batteries were that light. I connected two 3S batteries in series to equal a 6S battery. The total cost was $54 dollars, half as cheap as the big 6S. The two smaller batteries were also lighter and used less voltage over 9 minutes. The 6S battery was a little older so the test is not completely fair as far as flight time, but the cost of the two smaller batteries was much cheaper.
