I'm using Winston cells from Balqon. All cells are $1.10 per ahr and the discount cells are less. http://www.balqon.com/store.php#!/~/category/id=4218089&offset=0&sort=priceAsc

The Torqeedo "POWER 26-104" Lithium battery can be used for many electric propulsion systems, as well as of course the Torqeedo Cruise series outboards.
For those of you running a 48v nominal inboard (2) POWER 26-104 batteries in series will put you at a slightly higher operating voltage but would be well within the design range of most systems. Specs are 25.9v nominal, 29v fully charged, so 2 in series would be 58v max. They can be run in multiple parallel strings for more range.
This is a true 'marine' package, IP67 rated, with many electrical safety features built in (over current, thermal, BMS preventing over charging, over discharging, etc...) Weight is 54lbs, size is approx 23"x9"x10". MSRP is $2,599.00/per battery which puts you at $.96 cents/wh (2685wh total).
I have customers who use these daily (and very long days they are) in commercial service who are very happy with the performance.
Feel free to contact me off line if you have specific questions, as many of you already know I am a Torqeedo dealer.
