I am finished with this post. If I could figure out how to delete it I would. Thanks for the input.

Considering your last battery only lasted three years and the expected life span and warranties of Lithium batteries it would be better and cheaper to go with a Lithium marine battery in the long run. Not only will you get better performance but they can last 10 years or more with proper maintenance.

Yeah, as Smitty said, it's actually much more economical to get a Lithium battery. The upfront cost is a lot more, but you save in the long run, and the benefits of the decreased weight and longer run-time are really worth it. I personally couldn't have afforded to get my 100ah LiFePO4 if I'd gotten it from, say, Dakota Lithium or Norsk (the higher-end brands), but there are a few cheaper brands that have good products and often have stuff on good sales, such as Eco-worthy, Li-Time (I own one of theirs), and some others.

Watch some review videos and check out the websites of some of the cheaper brands. They should probably do the trick. I got a 100ah which only weighed 19 lbs from one of those brands Only costed about $360 all told.

On my boat, my cranking battery powers the motor, gauges, and 3 10" GPS/fishfinders, 1 with FFS. It is a group 31 battery. I have no problem with power by end of day. I do however, charge all my batteries when I get home. Sometimes I don't run the motor enough to fully charge the battery, and after a few trips this can cause problems. With 1fishfinder, you should have plenty of power by the end of day when starting with a fully charged battery. A 29 series battery should be lots, and it will fit in a standard battery tray (31's take a larger tray). I got 7 years with my last mixed use battery.

This battery is the first one from the dealership. Maybe with the next battery I get I will have more luck.
Thanks for the response

I bought one of the cheaper LiFePO4 batteries on Amazon to replace my lead acid battery I use for my trolling motor on my canoe (the lead acid battery was no longer holding a charge). I've used the LiFePO4 battery for one season and so far it has been great. I went with the Vatrer 12V 100AH.

One thing to keep in mind is a lot of the Lithium/LiFePO4 batteries cannot be used as starting/cranking batteries.

Thanks for taking the time to respond. I will be closing this post. All of the input was helpful. I have since met with a service fellow at the marina and had good talk with the fellas at Total Battery.
