If I installed that shunt on a 36v system with 3 batteries, would it give me the Ah remaining on 1 battery or all 3?

If switching from an existing (3) 12v in series setup to this single 36v, do you need to update the boat wiring? I'm noticing my current boat (Phoenix) has (2) positive cables and (2) negative cables currently hooked up. Would I just use 1 of each or can I connect all 4 wires to the single battery?

I, am working in a moto school in Québec where we have long winter 4 year ago we change all the batterie for lithium and kept them all winter long on intelligent charger in the spring 5 months later, all the bike started but all the batterie were not able to keep there charge So we haded to change them all again only after only one year. The next winter we were advised to charge them only one time in the middle of the winter for a day only, which we did, never have a problem since They lasted. we are talking 15 Honda 500 so I completely agree on what you talking Thanks for the video from a French Canadian 👍😊

"Probably in one of two boats"... pun intended? lol.

Can you please make a video of how you do a capacity test?

Micheal, what are the reasons a lithium batteries protection system will shut your battery down ? I know letting it go to 0 volts will shut it down. So if I’m on my boat and battery shuts down what are all the causes? And how would you get it back on while you are on the water ? Have ever had one that had plenty of charge turn off on the water ?

What happens when you don’t charge them and run out of battery on the water because you were trying to keep them in a range that you can’t actually measure?

Just charge to 14V with full absorption no harm done no matter how often you charge. Calendar aging is going to have more effect on cell life than constantly charging to 14 or 14,2V

How do you check the capacity of a battery?

Looks like a good option for a trolling motor, but a little overpriced for stationary solar battery bank, where size and weight don't matter as much as bulk storage.

can you try to look at some 24 an 36 volt also

Would the BMS system not manage the charge cycle to optimize these ranges- for example the power-pole charge? It seems logical to me that the BMS should account for this so all you have to do is plug them in and let the BMS manage the charge cycle?

So is there a way to test your batteries capacity?

So you are saying a DC to DC charger in an automotive application is no good

I just bought 2 WattCycle batteries. It was recommended by another popular channel, before I discovered your channel. I’m very happy to see that you also recommend the choice.

Loved the video. Thanks. I'm curious of what you think about the Watt Cycle 12v 300AH Mini battery. I'm thinking of building a couple of power boxes with this battery as the storage component.

Great educational video. I appreciate it. I have the same motor as you, similar boat. My question is what top RPM were you running on the prop you chose?

Tanks for edvice bro, mucho apreciado 😎

I wonder how much damage I’ve done? Charged it to 100% seventy times this summer. Now I know! I will draw it down to 50% for winter storage. Thanks for schooling us.

I tought the larger DOD the less cycles the batteries have, and also if the discharge is under 20-30% is does not even count as a cycel by some manufactors ?

My manufacturer states ro xharge to 14.6v. it seems very high compared to other brands.

Im using roughly 20% of my 60ah lithium battery when im out one day. Usally I dont charge it until I know im having more company in the boat or if im going away for 2-3 days.

Good information, this is the way we take care of our RC airplane batteries.

Unfortunately they don't work when it's cold. Rather have a c Delco voyager battery the last ones I had worked for 8 years then I put them in my wife's bass boat. She ran them for 5 years don't care mutch for your mouthwash

So how do you read the charge in it. Because it will run till is completely used up. How do you get a good reading

I'm looking to upgrade to lithium for next season and trying to decide if 1 24v 50ah battery will cover my needs. This video was very helpful!!

Very informative. Thank you. How do you find out the capacity of your lithium battery?

Awesome to learn this! So if I only have one charger connected to the lithiums and the agm - do I need two chargers now or is there a way to easily disconnect the lithiums? How do you do this? Maybe just let the agm be charged by engine when not charging all three?

So have you used it on your boat? I just made one for two finders, so far pretty nice

Very good information, however, I was looking for something a little more technical, as in charge rates in amps, and specific voltages so that I could monitor this stuff more closely and get it right.

Bro, I was both. I would fish, come home and put it directly on the charger. And all my lithiums are 100, 2-125ah and a 135ah. Just over the last couple months I’ve started getting at least 2 trips of fishing before charging. All my fishing trips are 4-8hrs. I will definitely use this info and run with it. Thanks so much. I do believe I was using Lithium Pro LiFePo4 also and had gotten pretty frustrated with them dying and malfunctioning on me. Now I know why.

Is the Li Time group 31 12.8v 100ah enough to power my 55lb thrust trolling motor for my jonboat? If so how long will it last me in a day(hrs) I usually keep my trolling motor setting on 2 or 3..

Great & awesome video!!! Thanks for sharing those tips. Very helpful. I don't own any lithium batteries yet but maybe looking into getting them once the regular acid batteries run their course. Any advice for the acid batteries?? Stay Safe & God Bless!!! 🤠👍

I keep my boat slipped most the time. I fish often but not many 8 hr days. I usually get 12 to 15 hrs (approximately) before I charge. What worries me, I charge on a generator and that may or may not be good I don't know. I also have a balancer on my three batteries if that helps, again I don't know. Thanks for the video. PS my next trolling motor setup will be a 24 volt.

Lithium and water DONT mix See examples on RUclips I ALWAYS run regular batteries they last plenty long enough

Don't own lithium batteries but it makes sense, I charge my batteries as soon as I get home so I can see why lithium owners would do exact that.

Makes sense! I was the guy that charged them after every outing!!! LOL I think I read on FB one of your comments about this a little while back and mine have been unplugged since..... I just added another 100ah so I have 36v for my trolling motor.... thought it would make my boat faster, but it really didn't.... I'm going out to the garage now and turn some stuff on and left them get down in the sweet spot.... thanks!!

Did you see the latest video from DIY Solar Power with Will Prowse about Lithium battery care ?

Learned something, just in time, because I just started using LiPo. Thanks.

I get that, but most quality batteries are rated for thousands of cycles. Most have 10+ year warranty. Better brands aren’t prorated warranties. If I get 6+ years I’m happy. If they last the warranty of 10 years, that’s great. But I’ll probably have new ones by then. When it comes to lithium, they are constantly getting better and less expensive. They will have evolved a lot in 10 years. I personally dont care about trying to get the full 5,000 or 10,000 cycles. I fish at least once a week, use 30-50% of my 60ah 36v. And 30-60% of my 100ah 12v electronics battery. I’m going to charge them every time. I’ll never ever come close to even using half the life. I’m sure you know if you use 30-50% like I do, then charge, that’s not a cycle. It takes at least two trips to register one charge cycle for me and most people. Even if I used a full cycle every trip,that’s 52 per year roughly. If I kept them 10 years, that’s only 520 cycles. But in reality, it’s more like 210 cycles in 10 years. Most of us will never reach the full life cycle. But I know people have had them from the beginning and never had an issue and still have their original ones. Hell, in a lot of cases, it’s probably better to kill it quicker. Then when they warranty them, you get a new battery and not only that most likely a better battery as cells and BMS technology is evolving. The 36v I just bought this a newer model, and the old version with different 18650 cells isn’t available anymore. so if I had the old one and killed it, I would get the new one or it minimum a really good discount on the new one which would be nice because if you want new batteries every 5 to 10 years could get a really good deal on new ones instead of buying them for full price

Will Prowse says to charge to 100 percent. This makes BMS balance cells.

I bought 2 lithium LiFePo4 batteries .. what do i need to measure the amount of charge remaining so I stay in the sweet range?

What is the better option 2 12 V 100ah or a 24V 100 for trolling motors?

Did you see (DIY Solor Power with Will Prowse today ? He kinda went against some norms of Lithium Battery Management!!! Have you ever checked his channel out ? He’s a Major lithium battery Nerd 😀

What is the voltage of a 100% charged battery?

Another thing that is awesome about the Bluetooth option on the LiTime isthe deactivate feature! With my phone I can just shut the power off to the leads with a press of a key!

I have the LiTime 24 volt 100 amp hour with Bluetooth! It goes in the hidden space below the rods in the bow of my Lund! The Bluetooth allows me to monitor and only charge when I get below 40%. I do not mount my 24 volt 20 amp lithium charger in the boat in order to protect it from damage. I ran a 10 g line to a storage compartment in the deck to easily hook up the charger without digging out the rods!

The name for these monitor : Battery Coulometer .

When you use solarpanels the batteriets will stay fullt charge, most of the time. How about that?

Been using one of these in the 31 group for over a year now in my tool trailer to power interior lights. It's been great but struggling in winter to keep it warm enough to use/charge. The truck doesn't charge enough while towing. I have to plug the trailer in 2twice a month usually to keep up with my power usage. Anything for keeping these warm? Solar panel and battery heating blanket? Litime has the 31 non Bluetooth on sale for 178 ea. I'm going to pick up 2 or 3 more to get more capacity.
