I first used Nicads in a model in 1963 and in my transmitters shortly
after. I have plug and forget chargers and battery testers for my
equipment. I have no need for more advanced technology that can
start fires if misused. Anything that stores power has the potential
of starting a fire but

An accurate statement would be why do folks not follow instructions, and use
due diligence with new technology? It certainly is not the battery or packs
fault when they fail...

Why do so many people want to put a fire bomb in a transmitter or in
a model other than electric? The NiMh batteries in my Evo will last
about four times longer than I will ever fly in one day. If, by
chance, I do fly longer than normal, then I will simply recharge the
transmitter with the Si
prizmatics would fit our current moldies, they offer no where NEAR the required
current demands due to their internal structure.
I am curious what you feel are the current demands of a typical 6-servo
TD ship.
I can give you some documented loads from other uses.

There are a few devices available now Bill that allow using a NiCD/MH charger
to charge Lithium technology, check the electric forums.

Very different technology;

locked down to the cell-count for that device, with other safegaurds.

Chip,
We've discussed dual battery packs before. For Nicad's and NiMH's it's a
reasonable approach. Though it was heatedly debated.
But with Lithium?? Dude, I don't know. I'd not be too cavalier with them.

I haven't seen many people discuss it, but I have been using Li-ion
