- I've had a lot of experience over the year with batteries, and although there is tons of information on them I think its all a bunch of numbers that don't really apply. This video might give a more common sense approach to buying batteries.

When I got my latest boat back in 2022 (a new 2022 BassCat Cougar), I had a clean sheet of paper to start with. I kept the AGM cranking battery from BassCat, but I installed a single 36V/40A NextGen Lithium for my Garmin Force TM. I don't fish at the level you do, so it works great for me. I can add one, or two more, if ever needed. I have cranking hooked to a MinnKota 4 bank charger, with the other 3 banks unused. I charge the NextGen with a stand alone. I never takes more than 30 minutes to bring it back to 100%. I rarely get the TM battery below 50% even after 5-6 hours of fishing. I'm an old guy, so that's a normal day for me. Great info as always. Very clean set up and rigging as well!
Perfect timing. I've gutted and been rebuilding my boat this winter and am just getting ready to buy new batteries. Thanks man
I can't help it. Here are your numbers. If you look up your trolling motor's amp draw you can tell how much battery power you need for agm. With lithium it is a little different because of how the power gets pulled. With your setup, you are talking abut running multiple 36V in a parallel wiring configuration which allows an even pull from the all the batteries. If you have three 100ah 36V batteries in parallel you get 300 ah of battery life. Traditionally, people run 12V batteries in a series configuration. When wired in series, the voltage of each battery in the series gets added up to each other creating an output that is the sum of the voltages. So if you have three 100ah 12V batteries in series they output 36 volts. However, the amp hours or battery life, doesn't add up. It stays the same. This essentially creates one 36V battery for the trolling motor to draw from giving you 100ah of life. Of course that is all on paper. Real results will vary.
You’re the one he was referring to 😂
I’m glad you said all this that way I didn’t have to type it all , 100% correct, the numbers are there for a reason , do the math and you should know appr time on water under certain load before you ever get on water
@@jmccOutdoors yeah, I think I'm responsible for the angry video, lol
Thanks for the info that anyone about to invest $1,000 + in batteries doesn’t already know. And then posting it after being politely asked not to.
I run impulse in both of our boats 12/24 in 12/36 in the other . 10 year warranty and bill stands behind his product. And awesome people to deal with. Great video Todd
Thanks, that's some great information that I haven't heard anywhere else.
I like your common sense way of looking at batteries. Time on the water way seems like the best way to determine what a battery can do.
Great video as always. Don't ever really comment but have to say. Impulse Lithium is the way to go!! Have their 16v on my graphs and live scope. Truly a game changer and they're great people!! Plan on getting their batteries for my Garmin Force. Keep up the great work Todd.
Awesome awesome Maaan common sense is a dying necessity haha. I have the 12v lithium battle born 100ah running 2 hds 12 live and 2 active targets..oh well. I wish i had bought a 16v just for the units and the black boxes. So my question is wouldnt that 16v run longer before dropping, like a 12v after 5.5hrs its like 11.9 11.8 you know what i mean ? Keep pushing these awesome informative videos, we enjoy em around here. Tight Lines & Be Safe Man 💪
Well it is simple math. You have 3 36V 60Amp. Wired together you have 180Amps. If you had 12v batteries 120ams each when you tie 3 together you have 36v 120Amps.
So yes your system last longer unless you had 3 12v 180amps batteries tied together.
But the most important thing you have is a back up. Of a 36V goes out you still have 36V. If you did 3 12v and one fails you arr SOL and left with 24V.
Correct
Great info as always
Great video. I'm looking into lithiums for my triton tr186 with 24 volt motor guide x5, 80 lb thrust. I'll check out the Impulse lithiums. So many companies..
Run close to the same set up but only 2 36v, run hard but not as hard as you! Never an issue at all! Great video!! FYI, impulse as well .
Impulse is located about 30 minutes from me in Alabama and that's the main reason I went with them. They are great guys and don't ask questions if you have an issue they just do what needs to be done
Good video and makes perfect sense. I think you are right on the 36vs12 as well. If you compare 3 12v size 31s to 3 36v 31s you usually get very close to the same price (keep it in the same battery brand) as well as the total amp hours. (3 12v 100 amp hour batteries will cost you about the same as 3 36v 33 amp hour batteries and the total of both are 36v and 100 amp hours). I am starting my 3rd season on Lithiums. I took a little different approach, I am running 4 12V 128 amp hour batteries. 1 is cranking and everything 12V (5 12 inch screens, live scope and 360) and 3 are running inline for 36v and also running the PPCharge. I did this for redundancy and if I lose my cranking battery I can use one of the TM batteries and since I run a Garmin force I can go 24V for the TM and not lose any time on the water. I find I get more benefit from the PPCharge on managing the loads on the batteries (transferring from the 36v side to the 12V side) than I get from charging on the run. Most of the water I fish is smaller so a 15 minute run is a long run - haha. The other great thing about the lithiums is that us old guys can still lift the size 31s.
I always take a spare trolling motor to tournaments also in cause it goes haywire or I hit something.I like your setup!
I could see buying these if I fished like you. They are really great but, if I told my wife I was going to buy $6000 plus on batteries. Well, I would hate to be eating at the circle K for dinner. Can’t let a cook like that out of the family. LOL 😂
Another good video... having just gone through the process of lithium upgrades for the trolling motor, there are a lot of misunderstandings of batteries and battery specs. With lithium you need to really evaluate the amp hour ratings on the battery. 36V sounds good until you realize how low the amp hour rating is on most. Volts are not amps... Reserve capacity associated with wet cell and agm style batteries does not equate to Lithium AH ratings. The average reserve capacity of a 12V 100Ah lead-acid battery is around 170-190 minutes, whereas the average reserve capacity of a 12V 100Ah lithium battery is about 240 minutes. Then you typically need specific chargers for 36v further increasing the changeover cost. The weight of traditional wet or agm's definitely had an impact on how long they lasted... they were properly built to deliver more power for longer periods of time (usually have higher reserve capacity).
I still think for the most part a really good wet cell battery with proper maintenance will suffice the majority of fishermen. For me the benefits of efficiency and near linear power supply during discharge was a key. Combined with some really good year end sales, I got three 12V 70AH lithium's for just a little more than the cost of AGM's. Someone else commented on the 50ah lithium's and I agree, i just don't see those meeting the needs of recreational fishermen much less touring pros. Everyone has to evaluate their needs. 70ah will suit me fine, I've gone all day the way I fish and I'm usually on the trolling motor a good bit.
The solar market is what is driving 12v lithium batteries and tech, not the marine industry. Then it comes down to whether you want to support all the cheap lithium batteries off Amazon or companies that are based in the US and support the fishing industry.
Great post Todd but you didn’t say what ah you had makes big difference. I am about to replace all my batteries and am strongly considering lithium batteries. But I have a question when they first came out fire was a big issue. I don’t want to burn my 100k boat because of a battery. What is your thought on fire hazard?
Im with you 100%. I had so many people tell me 3-50ah 12v batteries were plenty when shopping, but I just went ahead and got the 100ah. I’ve had multiple day where I have been below 5% charge. Rare, but it happens.
For redundancy I have 1-125 ah 12v, and 3-100 ah trolling. If any one battery fails I can run my force on 24 v and move one battery to cranking.
The Force will pull 56 amp on high. This could cause the 50ah BMS to shut down. 100Ah is a much better choice. IMO 60 AH would be the minimum.
@@bobbarnhill8557 you would not believe how many people insist 50ah is enough. They always fail to mention they fish for 5 hours on a nice morning 5 times per year.
If you hook electronics to one battery and Yamaha to the other but hook them in parallel doesn’t it just act as one battery?
What size 36v do you have 3 of? 40ah or 60 ah? I'm running 2 36v 40ah impulse and one 120 ah for cranking and everything else with power pole charge.
Li time batteries work well for me I run 4 lithium knock offs and one acid for cranking one lithium is for livescope 💯 % and other two graphs run on another battery and two 12v lithium for my minnkota 24v so everything is separated works I might try the 16v lithium for scope down the future but not sure what they cost😉
I've been running 2x100AH Amperetime (now LiTime) for a few years now to power my 24v Ultrex. I chase smallies and trout in current a lot and they have been amazing! No more weak batteries 3/4 of the way through the day.
Exactly what I wish I could do Todd. When I jump to Lithiums for the trolling motor, I will run at least 2 batteries. I'm always afraid I'll run current one's dead before EOD.
Great video, but can you use Lithium on a Yamaha Sho and not void the warranty? If so I'm switching
I’ve been running Ionic lithiums for a few years now and I can fish for days. I find it hard to believe you only got 3 hours off one battery!! Doesn’t seem right! Glad you have your setup that works for you.
That’s what everyone would say, these would be the arguments I got into. I would have the same conversations with my fishing buddies because I had some of these lithiums before others 6 months later they would come crying to me. It’s hard not to say I told you so to my buddies but I would
It is very easy to believe he ran that single battery down that quickly given how fast he uses his trolling motor.
@@toddcastledinefishing5924 I believe you brotha just crazy the amount of money we spend to get out and fish! Our equipment is that important. Looks like your setup is badass
Thanks Todd,a couple ?s.I have a 2116 r/t 178 ranger with lead batteries.Are the agm's worth the difference in price? Will my duel pro 3 bank charger be able to charge the agm properly without have to buy a different charger? What would you say is the best brand of lead and agm batteries? I just cant afford lithium i'm on a fixed income.Thanks again Todd.
Two more question will I have Yamaha 250 sho 4 stroke. Will it’s alternator charge the lithium battery. If not does it hurt the lithium battery by trying to charge it while you are running?
I do t fish as hard as you do but I love my lithium. They are from a different company but work very very well
Looks like those are 36v 40Ah so you have 120Ah total at 36v that is the exact same amount of run time and power as (3) 12v 120Ah batteries running in series for a 36v 120Ah system.
Now I still have more run time in my boat than what you have. Monster marine lithium 36v 73Ah is group 31 in size which is almost as much run time as 2 of your 40Ah there two of these gives me 146Ah of run time on 2 batteries and I guarantee you I can run all day hard as I can looking for beds and still won’t run out of power.
Also if you get 3 hrs out of (1) 36v 40Ah battery you will in fact get only 6hrs out of (2) 36v 40Ah batteries for 80Ah. It does in fact work straight like that. You must run the same speed, same time, same conditions but yes that’s all you get. You don’t get 6 more hours by adding the exact same size battery in parallel to the one you got 3hrs from. Put it on 10 take of on constant if you get 2 hours out of it do the same test with two batteries you’ll get 4hrs out of it (or whatever double is from the first battery) this part is that simple. Been running lithiums for nearly a decade longer than most.
Im a fisherman and sell thousands of lithium batteries and first question I ask all my customer is what style of fisherman are ya? Why? Because that will determine the runtime needed, In your case you are what I call a "power" fisherman and 100ah+ is needed and that handles the heavy load! My guess is your setup is less that 50ah per 36v battery that why you are running out of power and you have 3 of them in series. No one makes a 100ah+ 36v and if they do its $$$$. What I call the average fisherman 50ah is perfect for them and they can fish 2 days on a single charge without and issue. I can go on and on about this and break it down with numbers and on the water feedback on guys see pro with a certain setup and think they need it and they dont companies offereing certain setups that arent needed or wont suit their needs..
I agree I mentioned that a lot that most don’t need my setup: I also have not tried 2 impulse lithiums to see if I could, it was another brand, but after years of running out of batteries and not once in 20 years ever having enough power I wasn’t taking any chances. Plus I like having a backup. If I had 3 12 volts I’d still have a fourth as a backup everywhere I go, this saves me room so I don’t have too
Best battery company in the market right now.
it is
@toddcastledinefishing5924 I understand the battery setup, but my question is how does your boat perform with all lithiums. Did you lose any top end speed?
Once Elon Musk discovers bass fishing, this whole situation will change dramatically.
😂
Todd you have a Yamaha sho did they say anything to you about lithium battery voiding your warranty?
Thinking same thing. This needs to be addressed.
Are you using a stand alone battery for electronics? Maybe a 16v for electronics
Im run two Eternal lithium batteries. A 36v 100ah and a 12v 160ah. After a full day on high with a Garmin Force and a Z19 in the wind I only have used 15% of that 36v 100ah battey. With the 12v 160 ah i come in with 98% left after runing everything 12v plus 12" screens with livescope. Running charges the 12v near full all day long...
This is why I love lithium so much. Run all day and still have 80% left. Amazing advancement for bass fishing.
my question is I have a 24v minn kota maximum 70lbs thrust (chart say 42 amps) trolling motor , I fish anywhere between 4hr to 9hrs in a day (weekends) I'm not a power fisherman , my average speed is probably is 40% , I di turn it up if it's windy out ,what size battery would be good for me 2 50ah or 2 100ah
Straight up !!!
How long have you used impulse lithiums?
Love man just tried and tested facts
My problem is space related. I have a 2010 Nitro Z7. It can fit 3 full size batteries. I have a 24 volt Ultrex currently. So I can’t run 2 24 volt lithium to have a stand alone battery for graphs and a stand alone cranking battery. So I have 2 lead acid for troller and an AGM 31 cranking battery. I would love to have a stand alone battery for graphs and such. I fish about every other week for 8 or so hours per day. Any recommendations?
Some have put a battery for their electronics in another compartment in their boat closer to the screens
Get a dual purpose starting and deep cycle 135ah lithium. Single battery does both.
@@user-ju5dt9mx3m I’ve thought about that but adding weight to a rod locker? Not sure if I want to do that. They make the portable batteries for ice fishing setups too, but they say take them out of the boat to charge them. Kinda scary ha
@@Bp-dy9vl thanks. I’ll look into that, I’m about due for a new cranking battery.
I wish I could afford lithium
If/When the BMS kicks in and you're not near A/C power for the charger...You're screwed.
Get as many amp/hrs as you can afford. Have a 36v 100amp/hr batt that saved my bacon when the lower unit went out 4 miles from the ramp. That same battery will last me 5-7 days of normal fishing.
I think most people fish really slow, I've killed batteries way faster than you're supposed to Scoping in the summer when the fish are high and easy to see.
100% the battery "power" is the same on a 12v and 36v. If you watch someone tear down a lithium battery they can only have so many cells in there. So they are either wired in series for 12v or series for 36V. Same amount of stored energy. Smae prinicpal if you had 3 12v lead acid wired in parallel...you have a really big 12v battery. You wire them in series and you have 36v battery. Either way its still 3 batteries. Watch charging lithium is sub freezing temps...you can ruin them if they don't have built in warmers
The old military saying....Two is one and one is none...
Single A battery?
Battery for toys, single A double A and so on. More power you have to add bigger battery or more weight
@toddcastledinefishing5924 I agree with you about size and weight. I've just never heard of a single A. I know of D and C size but not A.
Anyway, great video and great advice on batteries. I love that setup.
@@scottdanielson4816 They exist, just more of a specialty item. The remotes on my ceiling fans use them. God only knows why.
Mechanic at cabelas is telling me lithium battery would void my warranty on Yamaha 250 sho 4 stroke
Nope! Same with Mercury!
All makes sense... common sense....
😂😂😂😂 great video
Three 36v would take me a month to run down.
Pretty sure you just sold $50K worth of batteries with this video.
I get that you don't care about the numbers however, without knowing the numbers and what they mean you are making uninformed buying decisions. If you would have known the max amp draw of your trolling motor then you could have calculated the minimum run time before you ever left your house. Look at the force tm at 24v max amp draw is 57 amps. With a 24v 60ah battery the minimum runtime would be 1.05 hrs. The 36v is 54 amps so, a 36v 60ah battery would give you a minimum of 1.11 hrs. With what you have 36v 180ah thats 3.3 hrs. That's on 100% constantly. If you don't believe me go out there and turn it on max and just run and you'll see the calculations are there. I get that you tournament guys run fast but, the average user isn't going to need to do that. Most users will be fine with 50ah to 100ah and never need more for a single day or even 2 without charging.
I do know the numbers I didn’t say I didn’t , I said I didn’t care anymore, I’ve been lied to my whole life about batteries. Second I said it 3 times that you probably didn’t need what my setup was. I said that people would get on here and talk about numbers and half that video was talking about setups and why I had the setup I did. I didn’t make uninformed buying decisions, this was in the past when there were not numbers on some of these things. The setup I have now I know what I have, this was in the past going back 20 years
Ii should have been a bit clearer when I used "you", sorry for that. I meant "you" as in the potential buyers. I also didn't mean for it to sound like you've made poor decisions that again was for potential buyers. I'm very sorry for the misunderstanding.
Ok I gotcha, yea I made another video dropping tomorrow as a spoof. Kinda funny since I’m joking around but it’s more to.m these companies that I wouldn’t say are trying to be deceitful just very argumentative
meh. rambling and incoherent. blah, blah, blah.. big battery = better. duh
You must be fun
