<DIV><FONT face=Arial size=2>The AGM (absorbed glass mat) deep cycle batteries
are probably a better choice than gel. At least the AGM can be charge at high
current (less time) than the gel cell and can cost less. I have an Optima 55
Ahr AGM (120 min @ 25A reserve rating) that works well for 3 charges using a
pair of Astros, will do a 4th charge if single chargers are used.
It accepts 55A @ 14.2V from the Iota, current tapers as batt voltage rises -
takes about 3hr until charge rate drops to 1A.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Also picked up a Honda EU2000i generator. This
thing is barely off idle running 4 Astros from an Iota supply. Picks up a
little if a 400W soldering iron and shop fan is added. Living in a hurricane
area I justified it as being able to also handle a few (select) household
items. It does seem a bit ironic to change to E for airplanes and buy a
gasoline fueled device to charge them -ugh!</FONT></DIV>

<DIV><FONT face=Arial size=2>The only battery giving me a problem is the
lead acid Marine 'deep discharge' battery used for field charging
of the lipos. It has lost about 70% of it's capacity in seven
months.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It provided six 12min flts when new and was
purchased from Academy Surplus for $40. It has provided a total of
maybe 80 flights ( 30 cycles ??? ). The problem is likely due to my
maintenance ( lack thereof ). I left the battery in a partial discharge
state sometmes for weeks. </FONT><FONT face=Arial size=2>You can find
maintenance needs on Google at agmbatteries, courtesy Earl
Haury.</FONT></DIV>

<DIV><FONT face=Arial size=2>West Mountain sells a gell cell, 54#, 84ah,
rated for 500 cycles @ 100% discharge ( 20hr discharge rate ), $149 del. I
will see how it performs under our conditions.</FONT></DIV>
