Ok fellas, what is the ultimate, best deep cycle battery for your boat out there? I've got to have the strongest and longest lasting one.

Odyssey extreme marine 31-pc215s /1500 run close to 300.00 each I have 3 on my 101 minkoto haven't run them down yet. I had three days on my electric on one trip. Plenty of power left. I have no complaints.

I'm currently running (2) Cabelas group 30 AGM powering a minnkota power drive 70 on a crestliner 17.5.
Getting 7-8 hours before feeling a drop in power. Next batteries will be group 31 led acid (most any name brand) they're cheap enough to replace twice as often. But if you truly want the looooongest lasting ..lithium ion wins hands down pound per pound.
Lithium pricing is way too much $ for my pay grade
