What is the cost to switch and any issues created by switching??

Depends on what regular battery and what lithium. Pick your poison and look at the price.

Also need to consider this as well, most chargers for wet-cell and AGM batteries will not properly charge a lithium battery.

As a Guide I have not ran the Lithium but if I can fish 250 plus days a year on regular batteries and get 3-4 years out of a Walmart Battery then I see a big difference in cost alone

My last two sets of 4 batteries from Walmart 3 years and 4 years at what $100 each.

Best bang for my buck. IMO

Really depends on what your usage will be. I switched to lithium to test out in a an xpress before putting in my bass boat. 100 percent convinced. If I can get 10-15 years from a battery that I can use 2-3 days without charging I'm all in. No more heavy lead batteries. My 2 12v 50ah are the same size as one 29 series lead. I literally put them both in a single battery tray and they weigh like 15lbs each.

The math I did based on the cost of wet cell and AGM, I would break even dollar wise if lithiums last somewhere between 3 and 4 times as long as wet cell and AGM. I think they will. Meanwhile I have 149 pounds less in my boat, less often and easier battery removal, improved battery duration and faster charging. If you want a guaranteed "lithium is cheaper" you won't hear it from me.

Whats it worth to never have to check water levels in your batteries?
Whats it worth to take up to 200#'s out of the back of the boat?
Whats it worth to not worry if your cranking battery will make it through the day with all your electronics running?
Whats it worth to not have your trolling motor run out of juice?


For me it was worth every penny of the almost $2200 I spent.

I did forget to mention 2 of these. Agree 100%

I planned ahead for once. My battery charger quit last year so I made sure I purchased a charger that was lithium compatible (NOCO GENIUS GENPRO10X4). Then earlier this year my batteries started to act up. I did some research and decided to take the plunge and came across a nice deal with Impulse Lithium batteries. They weren't much more expensive than new wet cells... Dan

I have also heard that if you have a mix of lithium and lead acid on the boat you will have charging problems.

Not if you have a proper charger.

Yea the guy that I know that is having issues probably has a charger on his boat that was made before the marine lithiums came out.

My old charger could be upgraded but their new ones have a lithium profile. It was so expensive to upgrade (ship, upgrade, ship back) I sold it and bought an Ionic to go with my batteries. Just the charger was 18 pounds lighter than the old one.

I went the same route.

For me I could not make the switch. Everyone's situation is different. I have room and not worried about weight. If not I might be able to justify. You can buy alot of celled batteries for the price of lithium.
