thanks brian. I actually just checked true-rc's site, and saw that it can charge at 21v. so I'm going to continue charging one pack at a time, and hopefully i'll be able to go run it today.
it's gonna take 2 hours to charge one at a time.. maybe i'll have my sister watch the packs, and go pick up another psu..
i know you're always supposed to monitor the chargers.. but if a cell blew up, what could i do anyways? i've got it in a lipo-sack sitting on a big piece of metal..
