What amp-hour rating are the gels you're talking about?  I didn't think that 
those were really designed to do all that much with high currents...
I used to sell those for various applications,  and there was a guy who 
wanted to use a 7 AH unit to intermittently supply short bursts of 3-4 amps 
for as much as a minute at a time.  I recommended that he get something a 
little heavier,  and sure enough,  he was back after a few weeks and that 
unit he insisted on getting was fairly well cooked.
FWIW,  I have a few 10 AH units and a somewhat bigger pile of 33 AH units 
sitting here that I've been putting some charge into.  I'm not sure what I'm 
going to *do* with these yet,  but...
