>>LiPo batteries are great for cranking amps but it is worth double checking the
capacity, particularly if you are flying an aircraft that relies on only
electric
pumps ( 914). The LTX9 has a capacity of only 3.6 AH.<<
When I fitted a a LiPro to my 912ULS Tri-gear, I worked through the static load
i.e. Radio, GPS, Master Solenoid, Transponder. and then dynamic load i.e. Radio
Transmitting, trimmer and flap operation. With a static load of 8 amps I have
2 hours of battery capability and can extend that if I close down transponder,
put GPS on internal battery and other measures. In other words I can cross
the channel and find an airfield to divert into.
If anyone is considering fitting a LiPro I recommend sitting down first and
working
out the electrical load factors first and then considering how much capacity
your would need to divert should you loose an alternator. It's done for IFR
capable aircraft as part of the design.
Fitting a LiPro is not all about weight saving and cranking capacity IMHO.

early
regulator failure but thats still original after 10 years and 700 hours.
