Jose - The N8XJK boost regulators will do what you want with a few caveats.
First, they do introduce some conversion inefficiency themselves - they will draw about 10% to 20% more power from the battery than will be delivered to your radio. Just the nature of boost converters. This will put quite a strain on your battery in any event. You won't get a full 22 amp hours of use from it, i.e. I wouldn't expect much more than an hour of operation at best before it became unusable, but until then everything should work well.. Second, since it is a switching type power supply it may introduce birdies on receive. Naturally this will be worse if near the antenna, or if there isn't a choke on the coax going to the antenna. N8XJK does have a more expensive converter that senses RF and only activates boost during transmit, and takes the converter out of the line on receive. That should take care of the birdie problem. I have used one of their converters in a marine environment, and it worked well. I haven't used one in portable ham operations.
