Hi John and all,
For us more casual users of a charger does anyone know of site that might
have a schematic for a homebrew charger that accomplishes the same things as
is being discussed here?
The A&A charger looks like it runs about $70, which is a fair price, but
basically I'm a cheapskate :) .
Thanks

Subject: Re: [Elecraft] K2 Battery Charging System With out Mods?
I use Don's system described below in #2) with the A&A charger and
recommend
it. It keeps the K2's battery healthy, and I also use it for other
gel-cell
batteries around the shack. Plus, when out in the field, the added power
jack on the back of tyhe K2 makes a convenient spot to connect an analog
expanded-scale DC voltmeter to monitor the state of charge (even though
the
K2 can also monitor its own voltage). The meter I use is a Zantum
Technologies model ZAPV15 "12 Volt Lead Acid Battery Capacity Charge
Meter"
with a nice multi-colored scale.

2) Make a direct connection to the battery and use a 2 or 3 state charger
designed specifically for charging gel cells. The A&A Smartcharger is one
example. See my website www.w3fpr.com for information related to 2)
above.
