Killer Amps
I want to pull ten amps out of a little 35 ah battery for one hour and then fully recharge. Will this heavy draw destroy the battery? I know it is a small battery.

A Camper Shell, for those who do not know about them, is simply a fiberglass shell that fits over the bed of a pickup. Mine creates a box approximately 6.5' X 5' X 4' which can easily be warmed with any kind of small heater. I am not talking freezing temperatures, just a little warmth on a cool Spring morning. Very practical. No furnace, no fireplace. The problem is actually to find a heater that is small enough. Typical 1,500 watt units or a Little Buddy is way overkill for the application. I carry a small AGM battery which proved incapable of operating the 250 watt electric heater. A 20 amp load slammed on a 35 ah battery pulled down the available juice to under 10 volts. Inverter disconnected the load. I would not have even tried the test had I remembered that the heater was 250 watts instead of 100.
