[Elecraft] KX3 and K3 on AGM batteries

[Gary Gregory]

Hi to the group.

I have been reading the recent postings on AGM battery use and some of the
set-ups being used seem a little odd to me.

I have in my Motorhome, 800W of solar panels @ 24V and a pair of 270aH AGM
batteries. I use 24vdc to 14vdc stepdown to power the K-Line and KX3/GS-3
screwdriver antenna.

Prior to installing the system I researched solar power regulated systems
and paid close attention to the controllers being used and looked at
battery longevity. Many folks I have met often stated their batteries were
not lasting for years and this was a common comment. So I set out to find
out why and what I uncovered was that there are controllers and controllers.

For anyone wanting to know more about what I ended up doing, feel free to
send me an email and I will send more information with brand/model numbers
and a wiring diagram on how it should be done to gain an 8 year life cycle
from AGM batteries and full control of your solar system with historical
data available so you can see over time just how your system is working.
You don't want to destroy expensive batteries I'm sure.

regards,
