Battery choices

[Planegary]

I was talking to a buddy that used to have a Mooney and he was singing the praises of the Odyssey battery over the Concorde. Anybody else have any input? I am not needing one right now but wanted this information for future use so I will be informed when the time arises

Last I heard, only one Odyssey battery is PMAed, and it requires a new battery box, STC, and field approval.

The Concorde is a great battery, lasts a long time, and just drops in with a logbook entry.

Agree.

As far as the Odyssey?  Caveat emptor.  There’s a reason the Concordes cost - and last - as long as they do.

It’s too bad that Odyssey batteries aren’t approved, the one in my RV4 is half the price of an equivalent Concord battery, and in my experience lasts just as long.

Lots of reviews for odyssey...

Few Mooney related...

Looks like a change of battery box is needed...

Making a switch an economic challenge...

These guys are delivering Lithiom ion batteries which are approx half the weight of the Concords in my Acclaim. Trouble is: the two heavy batteries serve as ballast, so cutting their weight would mean putting in Charlie weights in the tail.  Less weight because of the arm, of course, but no way to recover the full 30 ish pounds of weight.

I’ve had both in different airplanes  They are both excellent in my opinion

I think I’m finally heading toward a new concord - I’ve had one rolling for 7 years strong no minder.
