Thanks, hope this helps someone. I'm not a fan of adding anything that just doesn't belong there. Really what's there is enough, no printed frame needed, just adds weight. Three half-layers of shrink wrap is just enough. If the batteries are used as they should, there are no temperature problems, the battery immediately after landing is cooler than 2 minutes after landing. This is a sign of good cooling in the air. VTC6 Muratas are capable of giving 10A for a long time without heating up, they give 30A in bursts, they should not be loaded more than this value. On a 7-inch quad, two batteries are used in parallel, so 20A without a problem and a peak at 60A here and there. That's how it should be used.
Lion is not for freestyle, Lion is for LR cruising and here and there we can only go a little more ... this is what Lion batteries are designed for.

Lion cells do give off significant amounts of heat under constant discharge at higher currents. A lot of vape cell sights do extensive testing on all the different cells, like lygate.dk for example.
Constant discharge of a VTC6 cell at 15A results in a +46C temperature increase without any cooling. And for a higher discharge rate/lower capacity Molicel P28A at the same draw results in only +36C increase.

But depending on your ambient temperatures, you may NOT actually want to run your pack too cool as it would result in more voltage sag and reduce capacity. I guess some people flying in extreme cold/altitude actually wrap them in thermal insulation?

This chart is Molicel's manufacturer specs, it only shows a 2.8A discharge rate, so for 10/15A the sag would be even greater.

nice and informative sir! i actually did a quick fix testing for the front horizontally polarized T antenna with the stock RX located also in the front. it works much better than the previous installation strapped to the motor arm. BUT i will try to copy your diy rear antenna based on the list of materials if i cannot find anything local that has a long stock cable.

just finished a new batch 4s
