Yes, parallel charging is for "bulk charging" so you can get back to flying more quickly.  Every so often you need to charge each pack individually to monitor. 

As long as you're using packs that were purchased together and have been used together, it's all OK.

That I believe was his point on RCU. Which is obviously an easy work around.

It's not electrically possible to read each pack individually if they're connected in parallel.  Thats why every so often you charge a pack by itself. 

Some guys get all wrapped up and teary-eyed about parallel charging because they can't monitor each cell down to the 1/10000 Volt or MOhm every charge.  
The guys that get all apoplectic about parallel charging typically have never tried it, or did something illogical like connecting a brand new fully charged pack in parallel to an old, tired discharged pack and then wonder why it didn't work.

I believe his question on RCU is if it will do it while parallel charging and give readings on each pack. 
Will it do that?

Obviously he doesn't own one or is capable of reading the manual.  When you start a charge, cycle thru the pages until you get to one that says "Calculating Internal Resistance(%)".  After a few seconds, it shows all of the cells IR values throughout the entire cycle.

Hmmmmm.  There won't be an audience to Hoard's Memphis crew's "clinic" in Birmingham, because the contest is in Huntsville.  Reset your GPS units gentlemen.

We'll be "Ringing the School Bell" right after the pilots meeting tomorrow morning and puttin' on a clinic in both Advanced and Intermediate class.  Bring your paper and pencils so y'all can take notes . . .  We don't like to repeat ourselves . . . .
