Thanks Tord - that's a very comprehensive list of the dangers of the LiPo
cells. I guess we will probably learn to deal with the risks involved - just
as now we don't (much) consider the bombs we carry round with 'Primus' or
'Camp-Gaz' written on the side of the tin ;-)

Maybe I can have a special 'survival' mechanism that launches a big LiPo
cell up into the sky and shorts it out - to produce either a
seriously-visible distress flare & thunderclap or else a weapon against big
launches on auto-pilot ;-)

Instead of carrying the AC inverter, have you thought of attaching one or
more 'female' cigarette-lighter sockets to the big battery and then plugging
in all the car cables (cigarette-lighter charging cables) for the various
devices. That usually saves weight and some inefficiency (as you convert up
to 240V and then back down to DC). 

Even if the inverter is efficient (and at low loads, they rarely are); the
plug-packs or wall-warts (whatever name we use) are usually terrible - just
feel how hot they get.
