Lithium Iron Phosphate Rechargeable Battery
« on: Oct 14, 2020, 07:15 PM »
Looking at deep cycle storage batteries for the Ulterra, which still hasn't arrived yet.

Anyway, my son Jeff thinks we should go with AGM's for now.
At least until lithium batteries come down in price.

I have read tons!!!
But would certainly like someone's first hand experience here please.
Does a 100ah lithium actually run for 2X the time of a lead acid or AGM equivalent 100ah battery????
Is this really true??

I need to run my Ulterra for like 7-8 hrs, and maybe 10 if I can.
It won't be running at full bore, but still up like at 6-7 out of 10.
This is based on where I used to run the Terrova on the Lund.
(The Honda kicker did most of the work and the Terrova did the steering - but in higher wind/waves situations I needed a higher setting on the Terrova to hold course)

I was thinking a 100ah unit, but there are 200 and even 300 ah units.

Here is an example -

Anyway, let's get this discussion kicked in high gear.
I'm buying something in the spring and want to do my homework here.
Thanks!!!

You might get more action over on the ICE fishing site: https://www.iceshanty.com/ice_fishing/index.php

Listen to Jeff........  By the time the AGM's wear out, the lithiums will either be proven and come down in price or the class action suits will be starting......  Maybe inquire on the LOU site.
Bigger isn't always better but Size definitely Matters!

In all seriousness Iím following this thread to see what everyone has to say. Iím debating making the same jump.

You (and Jeff) are probably right.
Hereís my thoughts.
Has to do with actual use length, not life in years, but real time between charging.
Assuming a 100 Ah lead acid vs a 100 Ah lithium ion battery.
Iím reading that the lead acid voltage falls off a cliff at like 50-60% of the discharge time.  Where the lithium ion holds pretty much the full 12 volts out to 90-95% of the time.
So if Iím out there and get say 6 hrs with lead acid, is it true I could get 10-12 hrs with a lithium ion with the same Ah rating?
Money is always a factor of course.
But I had 4 lead acid batteries wired in series parallel on my Lund to get enough time out there trolling with my 24 volt 80# thrust Terrova.
Granted, I originally only had series 24ís and added a pair of 31ís to them.  So maybe had I had 31ís from the start I would not have needed to add another pair of batteries to them.
This time Iím going with a 36 volt 112# thrust Ulterra and will have three 31ís.
Iím wondering if Iíll run out of power on the longer days out on the water.
Has anyone gone from 31 lead acid to 31 lithium ion and can comment here with first hand experience.
Three 31 lead acid will weigh like 270 pounds.  Adding 2 more to them and Iím up around 550#, plus a 2nd three bank charger.  So maybe 600 pounds down in my cuddy.
The 3 lithium ions will weigh less than 100 total.

Well, it appears Jeff is now interested.
At least to investigate things.

Iíll keep you lamoís updated.
