Does any one use these? What are your opinions and are they a good deal??

Buy your TM batteries from Wal-Mart, and keep your receipt.  If your battery craps out there's always a Wally-World somewhere near-by.

What kind of batteries do they sell.

i have one of thier batteries for my 45 lb. thrust bass pro shops prowler trolling motor, i think they work pretty well, they hold a charge for a long time, you can ruun full power on your trolling motor for a while with out driaing your battery and after those long days it still has enough juice to take you to that last fishin spot, overall i think the are a pretty good deal considering they are only 50 dollars, and if you are wanting to get a trolling motor the prowler series from bass pro shops are pretty good as well
