Something for almost nothing
While trying to increase Mr Mangle's battery capacity, I took a gamble on a new Turnigy A-spec 3.7AH, 6S, 65C pack. I was using two separate 3.2 AH, 3S packs and Hobbyking listed the larger pack at almost the same weight.
When the new pack arrived today, it was only 17 grams heavier than the two smaller packs, while having and extra 500 mAH of energy - definitely something for almost nothing! All I need to do is open up the wrapping, add a centre tap wire and replace the wrapping
This is the business end of the pack with most of the kapton tape removed. Two centre-tap wires have been added; they only power one drive ESC each so I can get away with 14g wire. The A-spec pack construction looks just as good as the name brands, very similar to TP and Hyperion; if the performance matches the packaging I will be very happy.
With the pack all wrapped up again, it now weighs an extra 50 grams, which isn't surprising as I added extra Kapton tape, two layers of foam, a UMHW tape layer over the foam and extra thick heatshrink over that.
Given that the original battery I used in the UK only had a 2.7AH capacity, adding an extra 1 AH or 37% will deliver larger hits for longer. _________________ Australian 2015 Featherweight champion
