Glad to see you got a ReBel Battery. I have had my 100AH for a awhile now and so far so good. Aric from ReBel battery is really good at getting back to you with any issues you have. Costumer service is top notch. I have used the battery 3 times on Lake Erie, trolling 4 hrs plus each time and still have over 60% left. That's running full speed to my spot , than trolling at 1.8 to 2.5 mph for 4 hrs and than back. Game changer.

@@KayakhacksFishing I was in Fort Benning... once... accidentally.... My wife and I were headed to SGI, FL (she was driving) and she missed the exit off I-185 to get on US-280 (?). We cruised up to the entrance to the base (no way to turn around). We were in a fully packed Toyota Highlander with a trailer carrying a tarped Hobie PA17 and a bunch of boxes. The Sgt gave us a suspicious look - all he would have seen were a lot of boxes in the vehicle and a loaded 18' trailer covered by a tarp - I can only imagine what he was thinking. He asked some variation of , "can I help you?" And while my wife was beet red with embarrassment, I smiled and said, "sorry, we missed the exit and couldn't turn around." I believe he was mildly amused (and possibly relieved). In full drill-sgt voice he yelled something along the lines of, "ALL STOP" and the other gates stopped all activity. He then gave us instructions to swing around in front of everyone and we could use the exit (on the far end of the gates). I'm sure this was all protocol. Not knowing if we were really who we said we were (lost drivers who can't follow road signs), I suspect security was bumped to "FULL" until we were safely out of sight. Even though I'm sure we had at least one someone watching us VERY closely for any suspicious moves, I couldn't help laughing at the entire thing 😂

Hello again I have watched your video on lithium batteries where you compared Rebel vs acid battery. The rebel 50ah is a little out of my budget. Are there other brands you would recommend? Thanks Steve

[@KayakhacksFishing]

Unfortunately, these are all pricey. I recommend you shop around

[@jimwhite1557]

I have found that cheaper is often not the least expensive way to go. You got me all charged up about Lithium. Shoot, even my hearing aids have lithium batteries! Just charge them up and I’m ready to hear again. Of course, it tough when you lose one, like I did on Friday. I hav written them to see if they have a battery that would be a good cranking battery for my outboard motors that get recharged after each use by the engine.

[@KayakhacksFishing]

You kind of choke on the initial cost, though

[@kimmer6]

I firmly believe that cranking batteries need to be lead acid units. Using lithium batteries as a cranking battery has several problems. First, the BMS Battery Management System inside the lithium battery has a limit on amperage it can deliver. If you have a 100 amp BMS and the motor needs 150 amps to cold crank it, the BMS will shut the battery down like you turned a key off. A lead acid battery is rated in Cold Cranking Amps and its often 650 amps or more. Secondly, a lithium battery has very low internal resistance. That means it will take ALL of the charging amps it can get right up to the BMS cutoff limit. So if you run a lithium battery down to low state of charge, then crank up your boat engine, its charging system will run at peak until the battery is up to 100%. This might overheat and burn up your charging circuit. Motorhomers found this out by trying to charge lithium ''house batteries'' while driving. A 150 amp alternator will put out 150 amps for a minute or 2 but will overheat and burn up if its called on to put 150 amps out for 20 minutes or more. If you have a lead acid battery, the internal resistance is very high and the alternator will go to peak voltage but the amps will be low for a much longer charge time. Motorhome people actually install DC to DC chargers between their lithium battery banks and the engine alternator to limit charging amps between 20 and 40 amps. I hope this helps.

I'm thinking about grabbing a second battery strictly to extend our fishing trips- but is the 55lb weight worth it? or should we just bite the bullet and go with a big lithium battery? Thanks!

[@KayakhacksFishing]

If you can afford it, lithium is the way to go. Even on your deep cycle, you will not get all the amp hours of use out of it as a result of the depth of discharge issue. With lithium, you can discharge all the way to 0 and still get 100% of the power

[@MnNative]

When you compare amp hours, it would be nice to explain what that means in terms of run time. I have to research every few months. Also i think you should mention the need for a specific lithium charger... unless I'm confused. Otherwise nice, clear presentation. I'm 70+!

The trade off with lithium is the number of charge cycles... you may pay $500 for a 100ah lithium, but you’ll also get 2000-5000 charge cycles out of it. Where deep cycle batteries are doing well if you get 4 to 6 years out of them, Lithium batteries will last several times longer than that.

it is kind of a red herring. I think their post traces back to when Lithium batteries were running outputs greater than 14v. As I remember, the max on the Newport is 13.5. But... as I researched, I discovered that all the lithium phosphate batteries intended for trolling applications have a nominal voltage of around 12.8... like the Rebel. So, I do not think this is an issue any longer. I use my Rebel with my Newport and have not had a problem. The only think that does not work is the set of LED lights showing the remaining charge. But... you can use the bluetooth app for the Rebel to see a more accurate charge level.

[@KayakhacksFishing]

You need to look up the number of amps your motor draws at full power. So, multiply the amps times 6 hours and you will get the number of amp- hours you need. But, you are not using your motor for the entire 6 hours, say you use it half the time - then you can reduce the amp-hours you calculated by half. The result is the minimum size battery you should get. However, even though you can use 100% of the power in a lithium, a best practice is to not burn it all the way to zero. So add another 10-20% or so. This allows you to get the smallest cost battery.

Do not use lifepo4 on regular trolling motors, they burn the insulation on speed one and two when trolling for long period of time, the rheostat can not handle the heat produced. Lifepo4 can deliver more voltage, as they are not regulated unlike deep cycle batteries resulting in increased amperage which often will destroy your motor. Please check with the trolling manufacture before you ruin your rheostat. Only use them on variable speed trolling motors, or PWM

[@KayakhacksFishing]

thanks for the tip! I will

[@jarofclay8900]

Great technology but like everything else needs to be used with caution. If you have ever punctured a small aaa size type lithium battery you get a real appreciation of the potential dangers of larger lithium batteries. "Thermal runaway" is real and presents some degree of risk with lithium batteries. Batteries should not be charged if the battery temperature is above 110F or should not be discharged if above 140F. Worst case scenario is the cell temperatures get too high. This can cause the battery to vent and the lithium in the battery reacts with oxygen in the air. The result is battery failure (best case) and/or a lithium fire (worst case). A large lithium cell fire on a kayak in the middle of a lake is not a pleasant thought. Use caution and common sense to stay in the safe zone.

I have burst a few of them in testing and aside from a strange smell, there was no further reaction when exposed to air.

@@kimmer6 Thanks - I appreciate that additional information!

@@KayakhacksFishing Fish aren't scared of me. I'm not a very good fisherman and prefer chicken! But I built a Frankenstein Minn Kota box to hold a 200 amp hour lithium battery with on board 300 watt inverter for camping. I can attach a 1200 watt inverter to the wingnut terminals and cook up a stew with my 700 watt Instapot. I have the feeling that the 43 pound unit would run a trolling motor for quite a while. I like your videos!

[@KayakhacksFishing]

@@kimmer6 Wow! Sounds like a heck of a system! Thanks for your kind words!

[@iandtexarkana4549]

I would take them out on the water and do a real-life test. Sitting in a garage and contemplating will not do it.

[@mrsonar3656]

You should have compaired agm to lithium. So much mis information in this video. Some Lithiums have a 30% shut of that will not allow a full depth of discharge leaving you stuck on the water! They cost up to 5 times as much as agm batteries, read the reviews not all last 4000 cycles as claimed! I want to drink the cool aid They are just not there yet. I had a walmart lead acid battery last for 8 years and through two owners and I bought the boat back and it still worked! Not all acid batteries are bad.

[@KayakhacksFishing]

I appreciate your perspective. I did research this prior to making it. It is nice to see another opinion. Thanks

[@mrsonar3656]

This is real world results that I am bringing be to the table not a perspective. Lithium batteries have years to go before they replace AGM batteries.

[@stefanoskolovouris7223]

Lithium batteries are dangerous, in case of fire try to stop it, is not possible.

[@MarioBruneau]

Out of stock already!

[@KayakhacksFishing]

ouch

[@owljones3389]

So, you won't know that you're about to lose power to the trolling motor until it just stops. hmm. lol

[@KayakhacksFishing]

That's true. But, my lithium comes with a bluetooth app that shows the remaining power.

[@-WiseGuy-]

It's not Lithium ION Phosphate. It's Lithium IRON Phosphate.

[@KayakhacksFishing]

Thanks for that correction

[@jckdnls9292]

Can i borrow 600 bucks?

[@KayakhacksFishing]

Sadly, that is the huge downside of Lithium. Hopefully, it gets cheaper.

[@redwood1957]

You and cost never would have put the two of you together.

[@KayakhacksFishing]

lol! That's why the trade!

[@Cuspidor-spit-n-more]

At that price, you’ll lose in the long run so why would I waste my money by buying that, sorry.

[@KayakhacksFishing]

Thank you for your point of view
