The starter relay is max 75A, but whatever greater current pulses caused
by compression strokes I don't know. The voltage across a lead acid
battery drops significantly under high current draw; on a NiMH it does
not. In parallel it's going to appear to it as a partial dead short,
drawing very high current. My Makita cordless drill has a circuit
breaker to prevent the abuse if you stall the motor. Can you then rely
on this battery as emergency backup for the fuel pump? It seems at
least there will be insufficient time in flight to recharge it.

Just a few remarks,
In case of 2 batteries in parellel with different internal resistance,
like in the case with a lead acid and a NiMH, the current will be
delivered by the one with the lowest internal resisctance, in this case
the NiMH. Simply said: the lead battery does nothing at all. Furthermore
there will be complications during charging. These type of batteries can
not be connected in parellel, not without extra circuits like diodes or
relays.
Furthermore, starters are calculated with the normal powerdrop in mind,
in other words, feeding them with 12 V at "unlimited" current could burn
the starter, especially in cold conditions.
Looking a bit further at the advertised method of assembling the NiMH
packs on http://flydma.com/batteries/index.html it seems, that they are
soldered together, and i very much wonder how long the joints will stay
reliable in vibrating conditions. If these kind of battery packs would
be used for redundancy (=safety?) they could fail at the worst moment.
Not such a problem in a model plane maybe, but surely not advisably for
manned aircraft.

Jim,
I too am thinking about an EFIS system in my Europa. I'm curious how you came to
your decision, using an EFIS as a primary system "without" a lot of backup instruments.
Please e-mail me off the list at astills785@earthlink.com on your
ideas on this subject.
