Anyone fit a ODYSSEY PC680 BATTERY in there 911

[SEE YA]

Hello, all looks like I need a new battery thinking of one of these ?.
It looks like a better battery smaller and not so heavy.

Question has anybody else fitted one in there 911?.

[pikeyboy]

Not in a 911 but I had one in my race car and I used it to jump start my old merc E class diesel estate when I let the battery go flat.

Lots of people have on Rennlist

Sounds like you will definitely need a battery conditioner if the car is left for any length of time though

ha ha!..

I am fitting one as we speak, bought it from DemonTweeks last week, Odyssey 25 race battery. We run then on our race cars with no hassle, great cranking power but they don't hold as much power/life as standard, so you can't leave your lights on for as long without the engine running for example..

I also installed an FIA battery isolater switch.

the 25 battery only weighs 6.5kg!

£85+ battery
£35+ isolater switch

I didn't buy the bracket mate.. I made my own from 4mm alloy flat plate, 30mm deep, bolted from original earth mounts either side of the battery tray.. Also mounted the switch on a alloy plate bridged of the battery strap.. I will post some pics tomorrow.

Thanks for your time and help.

I have fitted a Lithium-Ytrium Battery from Thunder Sky (aircraft batteries)to my RS - more cranking power than the odyssey and holds the charge loads better (3% loss p.m.). The best bit is, that it is probably cheaper as well. Don't know if they have a UK dealer, here is a German distributor:

Thanks people for all the help.

What model did you fit noneedtolift and how did you ship it etc. I too would like one for my RS. I wonder how they compare to the Porsche Lightweight Battery, weight/power etc ?

I am buying one next week, with a bracket and two round connectors for to my 911 £110 including P&P.

I will have to make up another bracket, I would think anyway.
As I do not want to drill holes, in my bodywork on the inner wing.

Hi majordad,
just seen your reply, sorry! I have the 40AH variety.

However they have since changed the size of the 40AH batteries so you won't be able to fit the batterie cover. I know they were onto a solution (I got the last "old" shape) but you'll need to speak to them (I am happy to help as I speak German and also bought quite a lot of batteries from them for my electric boat so know them quite well now).

They do quite a lot of batteries for Porsche and told me that you can also get away with a 20AH Batterie (20AH Li Battery has twice the cranking Power of a Lead/Acid battery). I went for the 40AH just for the safety of added capacity. I also went for their battery cradle/holder as it fits onto the original battery tray so swapping batteries is easy.

Weight is about 9kgs for the 40, I believe it's 6kg for the 20AH. The Porsche Lithium Battery weighs the same as far as I know(6kg). Main differences:

Porsche is Lithium-Ion and has a battery- controller
Porsche costs about 2.000 € if I am correct

Have had it for about a year now and it's absolutely fine. TBH I couldn't ´feel a difference driving or lap-time wise but about 10kgs that high up must be good for something. Lot of weight saved for little money. Happy to make a picture and post if wanted.

Regards
Felix

Many thanks for that Felix. How much is carriage to the UK I wonder, appx. I would need them to send it here to Cork, Ireland, should not be that much more if coming from Germany.

[noneedtolift]

I'll ask!

[noneedtolift]

25 € for shipping, but the 40AH won't fit as it's to tall. You'll have to go for the 20AH which will work fine except for very, very low temps.

[majordad]

Many thanks, I off to Silverstone now for the britcar support race , so will chase it up on Tues next
