One other thing... DO include a fuse or circuit breaker at the battery

recommend a 5 amp push to reset CB, provided that you have some place

Molex or equivalent industrial quality crimp on connectors which are

That's my public service announcement for the day :-).

And Evan, why do we put fuses on the batteries and why do we use
aircraft wire? * I wonder if the aircraft in the following report had
a fused battery and aircraft wire?

We put the fuse right at to the battery so there is never a high
current running through the rest of the circuitry.
Wire short anywhere- fuse blows.
This simple protection prevents having to deal with the consequences
of many sins, including the PVC insulated wire many production gliders
are incorporating.
This is a simple and very useful safety enhancement which costs about
$3 and takes 20 minutes to accomplish.
Unless something falls on the battery terminals, you're pretty well
covered.
FWIW
