Michael.. Quick note to thank you (and maybe help your subscribers) for recommending a Lithium 100Ah battery to run my two Helix 12's and a Helix 15... I put this battery in the boat and started with 13.4 volts...ran for 7 hours yesterday with all three units on full time and came off the water with 12.6 volts on each unit...!! Thanks for your quick response and very accurate information...! God's Blessings on You and your family...

[@BassGuy1]

Exceptional! Thank you for the time and effort you put into this. The spreadsheet puts it all together for quick comparisons. Your work truly helps us to make intelligent decisions on power needs for our electronics. I am pulling the trigger on my lithium battery upgrades this month. Again, thank you!

This is excellent information. I am trying to buy a battery box to run my Garmin 93sv and a GoPro on my Kayak. If I filled out your spreadsheet correctly the 10AH LiFePO4 Battery would only last 5 hours. That is probably not enough and the Dakota power box I was looking at is only available in a 10AH version. Am I using the spreadsheet correctly? The 93sv was not listed so I used the 93UHD. The current battery I am using is a Bixpy 166 LiFePO4 and it is rated at 166Wh so it seems a 12 or 13 Amp hour battery gives me about the same.

Just wonder the net effect of starting, running on capacity on that battery. Not an issue with troller batteries obviously. Thx,

[@brettlatta]

I am getting 0.0 for Load and Power if I select Active_Target. Since you are using explicit lists, you should change the Range_Lookup in your VLOOKUP statements to FALSE so that it looks for an exact match in your list. I have tested on my end and it has corrected the issue for me. Alternatively you could use an Index Match configuration if you need to search a range in a direction other than leftmost to right. Thanks for the tool. This is a great resource!

I am running a 24v Minnkota Terrova with 2 12v Group 27 lead acid batteries. My cranking battery is a Group 24 12v. I have a fourth battery(Group 27 12v) that was my original TM battery before converting to a 24v TM. I am using it to run all of my fused accessories as well as my Lowrance Elite FS9 and HDS 7 Gen 3. This "house" battery is showing signs of decline, and I'm debating on my best course of action when the need arises. I'm not even sure I need a fourth battery.

[@goodmanfishing]

Since you have it, I would prefer to keep it in place. Something like a 50Ah will likely fit the bill. It's always preferred to keep any loads off of the cranking battery to help it live its best life. It's pretty important.

In the Battery_Calc-Share.xlsx sheet when I select Battery LiFePO4, 30ah, 12.8v and in Electronics Garmin Echomap_Ultra_106 and Garmin Livescope_LVS34, Cell c23 shows 2.8 (amps) but the formula for that cell looks up D14 in Lists and then multiplies it by 12.6 and then divides that result by $C$5 (12.8). My question is “why 12.6? In Lists, D14 seems to find Lead Acid 12.6 which doesn’t seem correct. I wonder if that is because it doesn’t find 30 in the table above it (it goes from 25 to 50 and does not include choices for 30 or 32 or 48). Can you explain why 12.6 would be appropriate here? By the way, I absolutely love this spreadsheet and applaud you for you excellent work on it.

[@goodmanfishing]

From what I find, most advertised manufacturer current draw specs are at 12.6v. So it converts that draw at 12.6v over to watts and then adjusts it to the battery voltage. I'll look at adding the capacities mentioned

[@jimwoodmansee]

I see. Thanks!@@goodmanfishing

[@tommckelvey3609]

I've yet to see any manufacturer specify the current draw of their graphs and or sonar modules at a voltage of 12.6V. Some use 12V (Garmin), others use 13V or 13.8V (Lowrance/Simrad), and others provide a voltage range (Hummingbird). Furuno specifies current draw at both 12V and 24V. In fact there is no one single voltage that “most manufacturers” specify the current draw of their graphs and sonar modules at.

Question Most of us run our electronics off a starting battery. If i was to swap my starting batt for lith then do you need to disconnect the alternator on the gas motor because that charge is not the right kind of out put for lith.

[@goodmanfishing]

It depends on what outboard you have, some of the newer ones don't have an issue charging a lithium. There are also specific dual purpose cranking lithiums that ensure good cranking power.

Do you have a spreadsheet for trolling motor battery? I'm looking to replace my 3 lead acid with 3 12v 100ah lithium or 2 36v 40ah lithium

[@goodmanfishing]

Trolling motors are a lot more tricky due to the varying amperage. The best way to compare those are to lead acid. 3 typical lead acid batteries will give you about 50Ah of energy each. So that converts to 36v 50Ah. If you were to buy a 36v 50Ah battery, that's the same energy as your lead acids, but with a lot better cycle life. If you were you buy 3x 100Ah batteries, that's 36v 100Ah, DOUBLE the capacity of your three lead acids. That's a lot... Two 36v 40Ah is about 1.5x the lead acid capacity.

I need your help understanding. I just bought an X2Power AGM 12v, 100ah, Grp 31 battery (February '24). I plugged the info into your excel ss and I don't know if im reaady it correct. At 75%, 12.4v, should last 2 hours before i hit that mark. Im not. My onboard charger charges battery, and multimeter gives me 13.03v. When i head for the lake, my units show charging with boat alternator at 14.2, however, once i stop, turn on the electronics (Livescope 12 inch, and Helix 12) i start at 12.7 and with 5 minutes it decreases to 12.4, litterally 5 minutes at 12.4. It will stay at 12.4 for about 20 minutes (i put my Helix 12 in standby) before it drops to 12.3. I go to start my boat engine and i get a low voltage (i have it set at 10.5v). I don't understand why im not getting a higher voltage to start with nor why it drops so quickly. Help?

[@goodmanfishing]

Voltage in the chart is without a load, I can't quite predict what the voltage will be with a load on it at a given depth of discharge. I suspect if you turn off your graphs after a known about of discharge, you'll see similar static voltage.

Is it better to get 12v 100ah and parallel or just get 12v 200 ah

[@goodmanfishing]

Depends on the intended use. For a boat, it's going to be hard to fit a 200Ah battery into a lot of places. If it will fit, a 200Ah is likely a little better value and you only need to charge the one battery

@@goodmanfishing That's incorrect, and the link that you yourself posted says so. The nominal voltage of a lead acid cell is 2.0V. The OCV of a "charged and rested" lead acid cell is 2.1V. Therefore the nominal voltage of a 12V lead acid battery is in fact 12.0V. The fully charged and rested voltage of a 12V lead acid battery is 12.6V. Here it is verbatim as per Battery University link that you posted: "The nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell."
