Battery Choice question for K1 & K2 portable use

[Doug Hensley]

I'd like to ask K1 & K2 owners who participate in Field Day (or similarly take their rigs to the park or camp site) if you found the "U1" size battery sufficient or did you find you had to exchange that for a larger, e.g. 75 Ah, battery ?   No KPA unit involved here; just barefoot K1 or K2.
I'm in an area with annual Hurricane Season alerts and also frequent power failures (that create surges spikes, etc.).  My idea is to just run my K1 & K2 barefoot off a sealed battery even at home and use a battery maintainer to keep the battery up.  But, once power is lost down here, we are often out for days so the capacity question comes up.
I would prefer responses direct to w5jv ...  at ...  hotmail.com
Thank you,
Doug

Doug--I run my barefoot K2 in the field using the internal battery, a 20 watt solar panel and a smart charger from A&A Engineering that doubles as a charger controller.  I usually run cw at 5 watts and so far that combination has worked well for me.
