Like John, I have several gell-cells. My MONGO Power Supply is a 20
amp/hr monster I got from the local NWS at Avoca airport. They regularly
change out these huge batteries and I was lucky to get mine in good
condition.

For use with the portagle 40 meter station which is built around a S&S
ARK-40, I have a 2.3 amp/hr unit with a Tejas charger taped to the side.

For the NorCal-40 I use TWO 1.3 amp/hr gell-cells in parallel. These,
like the 2.3 amp/hr unit, are small and relatively light weight.

I have found an excellent source for used gell-cells: namely a local
security firm that regularly changes them out of home and commercial
burgler alarms. Most of the time the batteries are good and will hold a
charge. Seldom do I have any throw aways.

Jus t some suggestions. Go out and be creative.
