    Welcome to the comments! Curious to hear your thoughts on the study and how you may adjust your charging methods.
    Also, I wanted to add some notes about manufacturers recommendations. I FULLY expect inconsistencies across the different manufacturers. Many will not banter a technical subject with you, or even myself. Keep in mind they ALL assemble someone else's battery cells. This testing is truly at a cell level AND most importantly apply across the CHEMISTRY of cell we are using. This isn't a debate of "quality" cells. It is chemistry and how that type of cell responds to its conditions.
    If your battery manufacturer disagrees with the study, be sure to ask for their source of testing and information. Let's make sure everyone is making educated recommendations and not based off of subjectivity or tribal knowledge. Trust, but verify. 👍

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, 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

    I have been following a protocol similar to what you have described. I use only the bulk charge program up to 90 percent capacity than stop. Every once in a while….I will let it charge to 100 percent. I don’t charge after an outing. I do it the day before I go fishing. On my last outing of the year, I store it for the winter without charging. I have been doing this religiously since I installed it. Time will tell…….

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.

At full charge I get 13.55 VDC on all 3. After a day of fishing I get 13.3 VDC. Now I know I'm good to go for day 2. 3- 100Ah give me a solid 3 days before I charge them.

  • @jasonbroom7147
    @jasonbroom7147 หลายเดือนก่อน +2

    I had never really thought about what you're saying, but it does make sense. With SLA or AGM, you really want to charge them back to 100% as soon as you get back from a fishing trip. With LFP trolling motor batteries, you're probably better off not charging them until just a few hours before you go out and draw them back down with a day's fishing. It's just a hard habit to break, especially if your boat is set up to charge all of the batteries by just plugging in one thing.
    I have two 100ah batteries, for a 24v system. I have to admit, they are rarely at 50% or less, and maybe that's a problem.

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน +2

      Agree on it being challenging if all of your batteries are tied to one plug-in. Ideally the battery companies need to start supporting maximum charge limits and be able to regulate the SOC charge limit.

    Awesome video, interesting info. I have an electric only setup with 36v (3×100ah AGM) 112lb Riptide in the back and 36v (3×80ah LiFePO4) 112lb Terrova on the front with voltage monitors on both. For me, a short day fishing is around 6 hours, and a long day during the summer is 12+ hrs fishing around 400 acre (electric only) reservoirs using both trolling motors. On a windy day, I'll use around 60-75%, but typically, I average right around 50-60%. I have to charge the batteries before I go fishing, or there won't be enough capacity for the next fishing trip. I fish every weekend. I plug in the chargers as soon as I get home, been doing that ever since the wet cell days. Going to be hard to break that habit and go against the manual of the lithium batteries. Those things are expensive and hope I can get several more years out of them. All that being said, your saying to not charge the batteries while stored and only charge them before you use them again. Trying to teach old dogs new tricks, this will be a hard adjustment.

    • @goodmanfishing

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน +1

      Partially charging or at least not storing them for extended periods is the message.
      For not storing them at high SOCs, you can run a basic maintainer on lead-acid or AGM cranking batteries. The night before the boat goes out, plug in the 4-bank.
      For partially charging, an outlet timer could be used to stop charging after a certain duration. This isn't fool proof, but it could be implemented. If your 100Ah batteries are at 50%, you have a 10a charger, you would turn off the charging after ~3 hours.
      Ultimately this information should get back to the battery manufacturers to provide their customers with more functionality in the batteries. The "bluetooth" equipped batteries are very basic. There should be target / max SOCs that can be set with occasionally charging to 100% for balancing.

Now on my kayak my battery is usually discharged about 2/3 or more so I use 12Ah of an 18Ah battery. This requires me to charge before use weekly, I do leave it all week in the discharged state and charge it fully the night before. Similar situation with my trolling motor battery I know I don’t need 100Ah so I use a 50Ah as I have a smaller aluminum boat and don’t need the bigger battery. Because of this I do need to charge before a trip or I’ll be cutting it close.

    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?

      Rather than just letting us see the status, we should be able to set charge limits and every "X" cycle let it charge to 100% to let it balance. Shouldn't be hard to do!

    What does the addition of brushless trolling motors mean in this conversation. I sometimes troll for 10 hours. That used to make a dent in 31 Group AGM's. Now, with my Lithiums, I bet it hardly matters. The challange is to know you have the juice for a tough day trolling into the wind on big water under rough conditions after 'not charging' the night before. Seems like a risk tradeoff?

      Exactly. Have to learn what you use. Go from there. If your at 100%, pay attention to days when you use TM most. See where you stand at night.
      If you got 70% remaining, after a day in high winds and current.
      Get the same result after 3,5,10 trips out. You know you'll go 2 days.
      Know exactly what your saying tho.
      I'm new to Lithium, but know enough about batteries in general.
      I'd follow his advice.
      Just take your time, learn what you need, before pushing the limit.
      I'd rather have 100% every morning. But of its hurting my batts, and I only use 25,35% the average day, I'll let it go 2 days.
      I'll be switching to brushless very soon, from an old 12v 35lb. Gona be a whole new learning experience for me. Can't wait to see what 2 100amp lithiums will do, with a Terrova Quest 24v. Lol

    Hope i read the reference correctly. From the Journal you referenced it seems they put around 1400 cycles on the batteries, at 40°C the best case going from 0-25% lost around 5% of the capacity. The batteries at worse case, 75% to 100%, the batteries lost 20% of capacity. So if i put 100 cycles on my batteries per year, even if i use it in the worse case i might lose 20% over 14 years. I don't remind having to replace my batteries every 10 years. The degradation will be more due to age than cycling. I am not worried about charging to 100% before i go out. Also if i just used the batteries from 0-25% state of charge i would need at least twice the batteries i currently have. So my take from this is I would just not store the batteries at full state of charge over the months i don't use them.

    • @db9818
      @db9818 หลายเดือนก่อน +1

      Knowing that storing is any length of time I typically just charge the night before I use them. I only fish once a week but my batteries aren’t oversized so they need to be charged before a trip. Ultimately from what I’ve gathered over the last 7yrs of using Li batteries is not storing them over 80%.

    • @howcroft22
      @howcroft22 หลายเดือนก่อน

      If you have average size lifepo4 batteries Where are you use maybe 50% on your average trips, you would be fishing a lot go through 100 cycles in a year. That’s probably four full 8-10 hour trips a week. I use maybe 50% at the most on my batteries and I charge them after and usually it takes at least two trips if not 3 before a charge cycle is recorded. So I usually fish once a week. 52 trips a year, that’s not even 52 charge cycles. It’s more like 25 at the most. Obviously, it depends on what percentage of your batteries you go through on average. But I don’t think a charge cycle registers until you use a full 100%. So if you only use 30% it’s going to take you at least three trips before it shows you went through a charge cycle. Even if you charge every trip.

I try to let the battery charge for 8-12 hours sometimes closer to 24 then unplug it until I use it every Sunday. On my app when it’s charged it does get to 100% but after a day unplugged it drops to 80%. It will maintain 80% for a couple months easily. My question is should I be trying to only charge it to 80% and removing it? Most trips I come home and it’s around 40% according to the app.

      Sounds like you have a good BMS that is taking care of your battery’s resting SOC on its own. I know my lithiums have a self-discharge rate at rest, and the BMS will cut that off around 80% if I recall correctly from the manufacturer info (I have no way of monitoring that). Sounds like I need to actually not worry about charging until the day before using though. Just don’t do like I did this week and fish Day 1 of our classic, then forgot to plug in that night due to some other mechanical distractions I had to take care of, then run out of juice for my graphs on Day 2 with an hour to go still…😂

      1) Some chargers have quick connections at the battery, you can disconnect the lithiums there.

      3) Install a maintainer on the lead-acid. When you get home plug in the maintainer only. The night before you go fishing, plug in your 3-bank charger.
      4) If you have bluetooth equipped batteries, you can usually toggle "off" the charging input. Until the evening before.

My buddy who converted to lithium years before I did operated the same way and his battery is currently somewhere around seven years old and still retains 95+% capacity (he has a smart charger now that shows this, but didn't for many years). I bought the same battery he has (Battleborn) and I had to have it replaced under warranty after three years because it dropped to 50% capacity. I believe it went bad due to a defect and not because of how I charged it, but I can't prove that.

    Hello my bass boat and motor 2019 my motor is f90 Yamaha it says in the manual not to use lithium batteries I still have the original AGM batteries that came with the boat I don’t know how much more time they have so I’ve been looking at lithium’s for the trolling motor and I would stay an AGM for the Yamaha it’s a 24 volt (2-12volt in series) now if have to wait to charge the lithium batteries is that going to hurt my AGM battery

      I run a 125 amp lithium Ionic battery on my 2005 yamaha f150. This battery also powers 4 graphs including livescope, two aerators and 2 talons. I am on my third year without any problems. I also run 2 100-amp Ionic batteries for my trolling motor. Ionics have Bluetooth so you can monitor them. Absolutely no problems.

      The local merc shop has had several pro xs motors fry stators from lithium batteries. Mercury even has a bulletin about it according to the dealer.

      @@Muskyfishn84 All I can say is that I run a Lithium Ionic125ah battery on my 2004 Yamaha F150 for 3 years now without any problems. Several other anglers in the fishing club also are running the same battery powering both Merc and Yamaha newer and older without problems. Could it be the problems they are running into is from cheap Lithium Batteries with BMS systems not programmed to be starter batteries?

      Two of them in the shop when I was there WERE Ionic batteries that caused the problem. It is due to the voltage being higher than lead acid and AGM, not the brand…

      @@Muskyfishn84 All I can say is that there are over 6 anglers I know of who use the Ionic batteries without any problems. I am more than happy with mine and will never go back to lead acid or AGM. All I can say to you is don't use them if you don't trust them, but for my two cents worth, I think your fears are overstated and I don't believe you when you say there are two in the shop with problems caused by Ionic Batteries.

    What is the voltage of a 100% charged battery?

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน +1

      Depends on the balance and the variance between the cells. Usually 13.4v-13.6v

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

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน

      The charger will charge at high voltage. The BMS will limit the actual voltage of the pack to ~13.4-13.6v

      2x100Ah will likely get you 2-3 average days of fishing.

    Thanks, great info. Does the charging voltage matter? I'm using a 5 amp charger at about 13.6 volts so it takes a while. I've seen people post that it needs to be 14 volts? I've seen people that say to top them off after every trip too.

      Lithium like high charging rate. 15A or 20A is ideal. But a 5 or 10 will work. I've been charging mine at 10Amps and they've been great for 4 years now

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน

      You do need to ensure it gets to the proper voltage when charging. Which charger are you using?

    • @JohnK-dv7pb
      @JohnK-dv7pb 4 วันที่ผ่านมา

      It's a noco 3 bank 5a. I was going to pull the onboard and get one 10a charger 1 bank and do them separately. I'll be unable to keep charging to the exact same level unless I go 100%. You think I ought to get a 2 bank for better control. Sorry, I didn't know you replied, thanks

    So is there a way to test your batteries capacity?

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน

      Yes sir. The basic way I use is one of these testers. Charge the battery and it records the wattage consumed and gives you the results.

    Do any smart chargers have a charging profile option to stop at 80%? Maybe they should. It would be a PITA to constantly monitor the SOC targeting 80%. The app doesn't even have a trigger or notification alarm for 80%. Maybe it should. If your boat is stored remotely or out of bluetooth range it's impracticable. Maybe I'll have to buy new batteries a little more often. Not a big deal.

    • @goodmanfishing
      @goodmanfishing  หลายเดือนก่อน

      There is a big need for battery manufacturers to provide more functionality to "bluetooth" equipped batteries. There's no reason they can't internally set a target charge SOC in the app and get there.
