Charging/wiring 2 x 2s Lipo's
 

I'm sure I asked this somewhere but can't find the thread, so:

If I want to use 2x2s stick lipo's as a 4s for 8th, presumably I wire it up identically to you do when using 2 saddle lipo cells to make 7.4, same principle?

As balancing is an issue, how many cycles could Ir un through charging them separately before the 2 stick packs get too out of whack?

Also, presumably charging them on different chargers to each other is a bad idea as they'll get more out of sync??
