Then again, they're new 30C packs so that's kind of expected.
Does anyone track how many cycles a given pack has been through, say with a sharpie dot on the side? Worth it? Seems like a good way to make sure you aren't just running one pack into the ground every time you have a free ten minutes to run out and burn through one, or to warn when a pack might be getting on the old side.

Still want to find a car adapter for the charger; not comfortable just clipping the direct-DC leads onto the car battery, as it lists a max input of 11.5-15V, and know some cars can spike up to 18V. Also kind of boring if you're the only one around, waiting the 30m/1h+ or so for the pack to charge up again.
I would suggest setting the timer so that after a flight the packs are at about 11.2-11.3 volts. This will ensure that you don't go past the 80% rule and will maximize your packs life.
On all of my batteries I put a piece of masking tape on them and then put a tick mark on them for every flight. I like to know how many cycles I have on my batteries just for my own knowledge. In addition to this I also keep track of the number of flights on my B450 and also write down the flight number when ever I do something to the heli. Such as a crash or replacing a part.
