Paul,
The ETX36C has been used successfully for years. The Rotax 914 charging
system needs to be slightly modified to bring the charging voltage into the
range the lithium battery likes (Jim and Heather brought that to my
attention). A diode on the 'C' terminal of the Ducati regulator is adequate
to fool the regulator into thinking the battery is at a slightly lower
voltage than it actually is and so it will up its charge voltage, placing
the battery into proper charging range. I think its 13.9 to 14.6 volts per
the data sheet, if memory serves.
This lithium battery has cell protection. It has internal circuitry that can
remove the battery from the circuit due to too low or too high voltages
(i.e. when it is overcharged or drained). A happily charged battery will
not disconnect from the airframe. It is wise to have a good metal battery
box for these in the unlikely event of a thermal fiasco. A thin Fiberfrax
layer can likely do wonders too.
The weight savings is amazing.. When you hold them in your hand, they feel
like a fake toy battery, but they will spin the engine right up for sure.

Hi All,
My trusty Odessey battery has died and gone to heaven (or wherever batteries
go).
I am seeking peoples experience with the new style Lithium batteries, and in
particular what can be sourced in the US.
Thanks, Paul
