More Turnigy 8000mA Graphene Battery
Part 1
I'll get through the boring stuff first but weather was good so the first flight on the Turnigy 8000mA 15C battery was done today.
Back to the boring stuff; I made up a rather long twin power adapter lead yesterday. By long I mean ~335mm. Because of the 10awg multi-strand wires used for the primary battery lead I felt it would be difficult, if not impossible, to make a short split power adapter that when combined with the bulk of the battery lead would allow the battery hatch to be closed and remain closed. Since the battery leaves a little room on both sides when fully installed in the battery bay I figured a longer adapter could be pushed between the battery and the outer battery frame to double back to the power plugs. The balance lead is long enough to place it on the opposite side of the battery bay between the battery and the inner frame, keeping the balance plug clear of the primary power wires. The end result is that it works as intended. If I was to do it again the adapter would be about 15mm shorter that what it is now. If anyone is interested I used 12awg multi-strand wire for all the adapter wires and had to use a pair of 120W soldering irons to heat up both sides of the wire junction at the same time to obtain a good solder joint. I tried a mini torch but those are somewhat of a pain to properly moderate wire temps and solder flow, even when using paste flux. The main power connector is an XT90 to avoid cutting the battery power lead to adapt a different connector.
The good stuff follows in Part 2
Edit: The mention of 8awg wire as the battery primary lead was a "senior moment" error. The actual wire size is 10awg.
