That is the battery that has the best in field workability...you can use almost anything to charge it, just dont let it go over 15v. drawback...heavy.
Also, look at actual power needed to charge your setup now, in a controlled environment. If that power is not good enough, your charging circuit in the tab might work too hard to regulate. Not knowing exactly what it needs, I would recommend AT LEAST 18000 mAhr capacity (most laptop packs are around 7000). This pack will suit, but recommend at least three of them...one in use, one charging, one for reserve http://californiapc.com/index.php?l=...detail&p=11512

While that is a mighty good looking setup it would have to wait a LONG time. That'd be something I'd want for a SHTF cache.
Right now I'm just looking for something small/medium to maintain GPS and radio power (Don't think I'd need more than 5v)
I would hate to go lugging around $800 worth of panels and batteries only to get clocked in the back of the head with a padlock on a chain and have everything stolen.

Already have them saved to the tablet, they take up most of the internal storage but I can get a high capacity flash drive to store them on.

Underemployed and annoyed at all the buereaucratic BS involved with being able to drive and own a motor vehicle. So probably not for a long time.
Mounting those afformentioned panels on a cargo rack would be great.
