Main battery advice

[kuee95]

I am running quite a few electronics on my boat. A ZX225.

I have dual 12" Helix on the Bow with a 360.
I have dual 12" Solix at the console.
Dual Ethernet Boxes.
Dual Power Poles.
Soon to add a Bobs Hydraulic Jack plate.
And of course all the usual stuff, Live Well, bilge, etc.

The boat came with a Continental XHD-31C, which has a RC of 195.

I have seen the battery voltage dip below 12V after just a few hours of fun fishing, no tournaments yet. So I anticipate that once my son and I do some 8 hour tournaments with live wells and more use that battery might not last.

I have seen some recommendations for some Batteries Plus AGM battery or a Northstar x900. Both batteries seem to have about the same specs though, except they are AGM vs wet.

Would it be worth upgrading to AGM vs the Continental Wet Cell? Based on specs it seems the answer is no, but I am not battery expert.

I already have 4 batteries in my boat and I am not sure where I would find room for another if that was the answer.

Check the specs on this one.

Better Cranking Amps, but same Reserve Capacity.

With that kind of load, no single battery of typical size and weight will get you through a day. If you remove the electronics and pumps from the cranking battery, you may be able to downsize the cranking battery to something like an Interstate XHD-24M to make some space.

Better....just run two 29/31s in parallel.

You're going to hear what you already mentioned...

Get the Northstar / Battery + AGM group 31 marine battery. It's the best on the market.

When the holidays pass, I'll be getting one for my rig and not looking back.

There's a reason why Interstates cost less.......................
