That's a little more reasonable but my current battery has 1,100 cold AMP cranking power.  A comparable Bansee lithium is almost $1,100 which is a measely 8 times more expensive and last only three times as long as an ordinary one.  And you still have to buy a lithium battery charger.  So it still doesn't make economic sense for a recreational boater IMO.
