Hi! Paul , I can't help you with technical comparisons but having the
Jabiru 3300 (it has six cylinders so two are coming on compression
together) and with two 13 AH red tops in parallel they have worked
flawlessly for in excess of six years and even with very negative temps
gave an immediate "light up" every time.
I always had to fly for up to an hour to be fully charged though and
after 3 starts within one hour it could need a second attempt.
All this was after it was necessary to perform jump starts from a plant
battery during the test flying. After which I moved the battery location
---From the back to the P1 Foot well with welding wire leads.
Red Tops profess to be "starter" batteries so they give a remarkably
instantaneous discharge as is required for the starter.

Can anyone give me some help with batteries? I've just priced up a
17AH 'Red Top' at 121 GBP. I can get hold of YUASA 17AH leads acid
gel batteries for 37GBP. THe only obvious difference to me is that
the Red Top product claims 625A cranking power at 20 degC and the
YUASA 450A. Would this lower power be enough for cranking the 914 or
am I missing another reason for spending an extra 100 quid?
Regards
Paul
