What do you backup the iota 75 with?

OK, now that you brought it up--FWIW--one charger isn't enough as you need a back-up.  Two really isn't enough because as you said you don't want to spend all night charging the night before and you really need a back-up for those two.  So practically, you really need three and you can knock out 6 sets in a couple hours.  I have a hard time burning through 5 sets after work--depending how many are at the field.  I have a pair of 6Ses that are back-ups for the 10Ses--otherwise I would have a fourth 10S.  If you have the energy left after flying, you could partially charge--say up to 65% or so and you could knock 'em all out in an hour the next flying eve.  I run them with an Iota 75 at 4.2 amps.

Another benefit would be the lack of a generator.  Just buy some extra Zippy packs and you won't need to charge at the field.
 
Hmmm, never thought of that. However, given the recent discussion about charging batteries unattended, I don't think I would want to spend the night in the garage the day before I go to the flying field. :-)
