When we were building our LIV, we found out that a Makita 9.6 v battery from 
our drill would power up the hydraulic pump enough to do 5 or 6 cycles of the 
gear!

It was an amazing thing, especially when we compared that to lifting a single 
wheel by hand.  The little batteries pack a big punch.

The upshot of this is that I have been thinking about taking the case of an 
old Makita battery charger, cutting it apart, and making a mount somewhere in 
the cockpit to use for the 9.6 v as a backup in flight...
 
The battery itself weighs about a pound.  I would be surprised if it would 
not be able to power the instruments for more than a half hour, including a 
gear extension.

Additionally, now Makita has come out with a 9.6 v NiMH battery that has 
about 60% more oomph than the older configuration.  

Image, maybe the new battery will cycle the gear 6-8 cycles!  And it is small 
enough to hold in your hand.
