Folks,
So my wife and I show dogs. Just upgraded our fifth wheel and am impressed with the LiPO I put in. We show Cairn Terriers, so these are not dogs that get a full up shampoo and need an hour to blow dry, but there are times when being able to fire up a blow drier for a few minutes would be handy. It is way over kill to carry a generator just for this, and if you are indoors they are out of the question. I am looking for a solution that can supply a 1500W blow dryer for about 15 minutes, maybe 20. It would be an intermittent profile, with heat on for 45 seconds, then off for 30, or similar. And it must be something my wife would be willing to carry, but it could be a two or three trip device.
My current thought is that two or three 50Ah batteries could do the trick. That is less than 20 lbs per battery. Dakota has a 54 ah 12v rated at 50A continuous. So three would get me 1800 watts, I should be able to invert that to 1500 watts without any huge issue. Now that should let me run a blow dryer for almost an hour, which is way more than I need.
So.... How far can you push continuous amps into the peak amp territory for how long. The max 10 second pulse is 100 amps, so two batteries is 2400 watts which is more than I need. Trying to find a solutoin that gives me the Watts I need, but not for five times as long as I need. Could I push a battery rated for 50A continuous to 75A for a few minutes, if its max was 100A. Or would that degrade the battery?
Should I be looking at a different chemistry?
Any help is appreciated.
Thanks
