Frank, I have a problem with those Peak Batteries, the web site
doesn't give enough information. Size, what kind of charger, etc.
Maybe you or someone could dig into it a little and report back. I did
read the article in Soaring but felt it was thin in places.

Take a look at Scott Fletcher's article in this month's Soaring
Magazine. *While very expensive (about 5x), the Li-Fe-Po (Lithium-Iron-
Phosphate) battery pack is a lot better suited to soaring use than
either Li-ion or SLA batteries. *The K2 Energy (http://www.peakbattery.com/) 12V 10AH pack is the same size and form factor

Brian,

The K2 site sells a compatible charger (which btw is also much smaller/
lighter than my older VDC Electronics Battery Minder Plus), and will
charge two K2 LiFePo batteries in parallel. Cost for one battery, one
charger and shipping to Columbus OH was about $242 US.

The combination is much more expensive than my SLA setup. However,
when I consider the cost of modifying my battery compartments to
accommodate larger batteries, or the potential cost (i.e., my life!)
of not having a transponder/FLARM next year, I'm comfortable with the
tradeoff ;-).
