My situation: this winter I'm upgrading from Rotax 912UL to 912S 100hp, but
keeping
the installation in the Classic engine bearer and retaining the original
cowlings and firewall forward as far as possible. Therefore I MUST keep the old
shorter starter motor.
For C of G reasons, the battery must be mounted in the rear fuselage behind the
old (smaller) baggage bay and therefore the battery must be very safe and immune
---From risks of overheating. At the moment I have a simple ride-on lawnmower
lead-acid battery, which might not have enough "oomph" to start the higher
compression
S engine.
What I'm hoping you can tell me is which is the most common battery used in UK
LAA Permit Europas and referring to a friend's quote "I can't remember what the
system voltage is with the engine running, but the odysseys need 14.1 to 14.7v
to ensure avoidance of both sulphation and overcharging", should I be installing
a different rectifier/regulator?
My 912UL engine only produces a maximum of 14.2 volts. Maybe I can manage with
the ride-on lawnmower battery, but I doubt it.
