I ran my club's FD GOTA station off battery/solar power this year. The
GOTA station was in heavy use for about half the 24 hour period, and
lighter use for the rest.
Over that contest and several others, I've developed the following
guidelines for my K3:

batteryspace.com has a 20A LiFEPO3 battery for $120 and weighs 7lb, half of
what lead acid does. Good for a couple of hrs at 100W level. This battery
charges real fast.

I have found some that will fit - or so it seems - but none of them use
all the available space, and as a result, are less powerful than might
be had if all the space is used. Of course, external ba

Strictly depends on the power level you intend to run. I ran my KX3 at 5w
for all of Field Day, and for a two-day camping trip last weekend without
charging in between. It's a "K2 Energy" lithium ion and weighs just a few
ounces. Couldnt be happier with it. After 4 days of off-on operating,
Hi Paul,
I run my K3 at 100 watts out using a 35 Ah SLA battery. (Powersonic
PS-12350NB) I chose that size because it is about the heaviest one I can lift
easily. I have run it for hours, in fact have never been able to run it down.
Good idea to get a Powersonic charger that matches the bat
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 tabl
Paul,
you will get more meaningful replies if you state what power level for TX.
Are you asking about a 10W K3, or 100W version?
