good idea.
a variant is to have foreflight on your iphone too.
Along the recharge path, you can get a battery to plug the ipad into from Sporty's.   Some people are now advertising 28V -> USB cigarette lighter chargers also.

I'm not a fan of big lead/acid batteries on my side of the firewall.   Had a friend get smoked out in a T210 from a battery gone wild.   He made it but it wasn't fun.

hi there

DO YOU RELY ON AN ipad FOR NAVIGATION?

 i do, and on long trips with hard IFR at the  end of the trip. 

 i keep in the plane a charged 12volt Car Starting Battery with a provision for using a cigarette plug to charge the ipad. 
i have found that i can more or less maintain the ipad charge; but not increase the ipad charge.

Thus, while addressing this problem, i had had an epiphany; why not a second ipad.

i use the ipad for approach plates and VFR charts and most IFR plates.

Note that much of my flying is on the east coast, from New England to the bottom of Florida and i retain 2 Charts,  NE SE East Coast Jepp chart subscription.

but if i had a ipad failure, i would have an increased load at a time that the work load was already increasing.

Yes, i can get information from the GNS 530. but why not have redundancy.

THINK OF IT THIS WAY:

we build our airplanes with redundant NavComs because we assume that having a back up is a safety feature
ergo,

I HAVE PURCHASED A SECOND IPAD.

it will stay charged and powered down as a backup in case of a failure or a low battery condition.
