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?

Yeah, there's one convert, for sure!

Btw, if anyone wonders where to get them, McMaster Carr is a good
source of Molex connectors and crimp on terminals. Get a good quality
crimper and a wire stripper while you are at it. They also sell
teflon insulated wire. Mouser Electronics is another source for good
quality electrical bits, including circuit breakers (but not teflon
wire IIRC). Some of the glider supply guys have a pretty good
selection of stuff too.

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.
