[Elecraft] K3 Power Supply

[Thom LaCosta]

Looking for suggestions for a power supply for the K3/100

The only thing I have handy(well, if I can get them upstairs) are 
some sealed lead acid batteries from motorized carts.

I have a few that are 34ah and at least one that is 55ah and one of 
the chargers that autosenses battery charge level.

Seems to me this should do the job, but I've never run a 100 watt rig 
on batteries, so I really don;t know.

thanks in advance for suggestions.
