Paul,
You did not say whether that is a K3/10 or K3/100 and whether you have
the extra current draw of the subRX, nor what your transmit power level
would be, so we cannot give you a realistic answer.
If you are backpacking, you will want the least weight, but if you are
going to a picnic table from your vehicle and have a hand-truck to carry
the battery, I use a 75 ampere-hr AGM battery. If I have to carry the
batteries in my hand, I operate at 10 watts or less and use a couple of
7AH Gel Cells (SLA). I like the reliability and safety of SLA
technology despite its heaver weight than more modern battery technologies.
73,

I would appreciate knowing the experiences of folks who have run their K3 on
battery power for several (4-8?) hrs., with perhaps a 20% TX duty cycle. What
types and sizes of batteries seem to be the best balance of staying power and
portability?
