The diode protects the radio/battery if you plug a charger in that's
backwards, or a piece of metals jammed in there and shorts it out.

It also prevents you from discharging your TX battary through the
jack, and stops some chargers from working (but not the Triton.)

Some chargers have `polyfuses' rather than diodes. This is a
self-resetting fuse. It'll protect you against that hunk of metal
shorting it out, but you can still discharge through it I think. (And
it probably won't protect you from a backwards wired charger. JR
chargers are backwards compared to Futaba chargers, for example.)

----- snip -----

RayChem PolySwitch resettable fuse. It looks just like a dipped
polyester capacitor. Standard practice is to remove the original
charge protection diode and install the PolySwitch. The ones I use are
fully bidirectional, will 'carry' 3 amps, and will open at 5 amps.
They will protect from both external shorts and backwards connected
chargers. The benefit is that they will allow a transmitter pack to be
cycled (discharged/charged) from the charge jack without removing or
disconnecting the pack's connector under the battery access door.
Cycling allows you to maintain full battery pack capacity and gives you
a baseline to compare to as the pack ages. I believe that, at one
time, Futaba Service would install the PloySwitch for a fee, but any
reasonably competent solderer can do it.

I'll be ordering some more PolySwitches soon.
