Lithium Ion Battery Cost ???

Rennline has a couple options with 1 that does not require a trickle charger. A trickle charger is needed when using an Odyssey 680, which is a general purpose motorcycle battery. The Odyssey 680 is 14-16 lbs (depending on version) with 680 cranking amps and a 17 amp hour capacity. The capacity and cranking amps are plenty for a motorcycle, but not exactly plentiful for a car. With the Rennline bracket, weight is 16-18 lbs.
Here is info on the Odyssey 680:

For normal driving applications, Rennline has a second option using an Odyssey 925 battery. The Odyssey 925 is a compact battery designed for normal automotive use. The Odyssey 925 is 24-26 lbs (depending on version) with 925 cranking amps and a 28 amp hour capacity. Cranking amps are higher than most OEM batteries and plenty of reserve capacity. With the Rennline bracket, weight is 26-28 lbs. It is 10 lbs heavier than the 680 battery, but still a sustantual weight savings over the stock battery and usable for every day.

Odyssey batteries are great. I used the PC 625 for many years in my Miura S (which sat far too often). They have plenty of cold cranking power, but little reserve. Odysseys work well in situations where they sit, as long as the battery is disconnected.
The PC 925 in my wife's Dino is still working after 5 years.
However, in my experience, these things are easily killed when allowed to fully discharge. That's what happened with first battery in both cars; service guys (waiting for parts) had the cars for too long and didn't use the battery disconnect switch.

If the stock battery weighs in at 43 lbs
(Guide Translation) :Lithium-ion vehicle battery (18 Ah) also settled. For use for example on the track instead of the standard car battery with a weight advantage of over 10 kg
Savings 22 lbs
Lithium-ion vehicle battery weight =21 lbs
For only 1904 euro.US$1900
Pretty steep price price for weight savings
I trust for that money the battery has a Porsche crest on it
Interesting order guide shows the battery is GT3 available in Europe as shown in Supertest specs (post #6)

191 Lightweight Lithium-Ion Battery. Reduces weight from standard battery by over 22 pounds. Note: The functionality of this battery is limited at temperatures below 32 degrees F. This option is not recommended for vehicles that may be driven at temeperatures below freezing. Available beginning approximately 01/2010.
911 GT3 $1,700
911 GT3 RS $1,700
So now we know weight saving and price. Anyone know if aftermarket alternatives have the same ambient temperature limitations?
