I'm debating going from manual to electric downriggers.  I'm curious if people use an additional battery for them or do you just hookup to your main starting battery?  I can't really use my trolling motor batteries since that's not a 12 volt system.  I do run a kicker so it would be charging a little bit from that.

My other question is that I would stack lines on one rigger.  Is that easier to do with a slower retrieve vs a quick retrieve of the ball?  I saw quite a difference in speeds between Big Jon and Cannon for instance.  I was thinking I'd like it to be a little slower, but I have no experience with a downrigger that comes up very quickly either.
