Do battery brands matter
Well to me the warranty is what matters along with a brands reputation
Yes and no I just purchased 2 DrPrepare 12 volt 100AH Lifepo4 batteries delivered for $418 since I am a recreational angler if I have a warranty issue it`s not going to be the end of the world. I can slap in a 12 volt LA hooked to the Lifepo4 battery to get by until the issue is resolved. I could replace these two just about three times over at the price of some of the same size Lithium batteries. Like anything else you are paying for that warranty and customer service as it is built into the cost whether you use it or not. For me personally it is not a big deal that decision has to be yours.
If you want the ~10yr warranty you should probably pick a real company that will be around that long. Most of the amazon batteries are sold under fake chinese companies that will not back up their batteries past when the listing is available.
If its cheap enough and you want to take that risk then go for it, plenty of people do.

No you cant. You cant add a lead acid in series or parallel to a lithium, the voltages are totally different and the weakest link will get fried.

I just saw a Youtube channel in which the owner makes Lithium batteries in his US shop. He said if you need a repair you can bring the battery in and they will fix it while you wait. I found his Facebook page but I could not find any pricing information. He is out of Flora, Mississippi. He said condensation ruin more lithium batteries than anything else.
How would different voltages "fry" either if in series? If the guy is using 12 volts batteries it's 99% of the time in series (to get 24 volts or 36 volts)
When batteries are connected in series the voltages are add to each other, no competing against each other. The only down side I see is that you will only have the capacity of the "smaller" one. (ie a 100ah 12 volt connected in series with a 50ah 12 volt battery will provide you with 50ah, not 100ah like would be with 2 100ah ones)
In series for 24v will not pull equally from each battery. As the lead acid gets low (below 12v) it will pull more amps from the lower voltage battery than it will the lithium, draining it even faster until eventually the lead acid is pulled down so low it gets damaged. You wont know there is an issue because the lithiums constant
13.1-13.3v will continue to produce 23v+ when the lead is toasted and the motor will continue to work somewhat well.
Never ever ever mix battery chemistry, from AAA up to deep cycles....

I’d talk to the manufacturer of my lithium battery before I mixed them with lead acid.
Please enlighten us as to HOW the different amounts of current will be "pulled" from each battery. Hint - it doesn't. I mean are you saying that if you put an amp meter in series on the positive lead of each battery you will get different amperage readings? Won't happen in theory nor in reality.
Now if you were to let either battery draw down too far either could be damaged, but remember he is looking at it as a back up, in case something were to happen to one of his batteries. That's what he said. He's not using it daily and draining it down past it's ideal usability.
Of course it's not an ideal situation to "mix" battery types, but in this situation would be viable backup as @bricks suggests.
You should talk to a lithium battery professional. You are incorrect. The amps are drawn dependant on voltage supplied, no two batteries in series ever draw equally unless the voltages are absolutely equal (like two lithium) otherwise the battery with the lowest voltage will have more amps drawn from it than the others. Its just typically they are so close when talking two lead acids that it wont be noticeable. But one battery at 13.3-13.1v and the other 12.4-10.9v is a huge difference and you will roast that lead acid battery.
Thats just how it works. Thats why you cant mix lead acid with AGM as well, same thing will happen.
You could definitely do it in an emergency situation, but be careful not to draw the LA too far down.
You can draw a lithium down as far as you want, so your comment of "drawing either one down too far will damage them" is completely incorrect. Ive had my Ionics draw down to 0% and too low for the BMS to even turn on when i accidentally left my trolling motor plugged in and on over winter. I jumped them using an old school charger to wake up the BMS and they both charged to 100% and say 100% healthy in all cells in the app.

You've been listening to a battery salesman, not a battery professional. You're repeating what you have been told, not what you have learned. That's how discussions turn into arguments. But at least it looks like you now agree that it will work in the "to get by" situation mentioned by @Bricks. I guess you'll take back the "No you can't" comment you made to him? https://www.crappie.com/crappie/fish...s/#post4440524
I’ve watch a lot of YT videos of lithiums being tore down,and read a lot on other forums,looks like the BMS is the weak point on all of them. If or when I switch, it will be a Fourth of July,Black Friday sale or watch for deals in the threads of other forums, BBC had a thread (36 volt 60 amp hour for $290) a week ago.
Wally World group 31s lead acid arent a $100 anymore around here closer to $120 I see 100amp hour lithiums for $180 on sale,(my work boots cost more then that and they only last a year;) companies selling the same size lithium for 4-5 times the price with the same (China)components is legal robbery.lol. I,ll take my chances on warranty…
Hang on folks- the lithium prices are gonna start dropping like a rock soon! :twocents
Can you expand on your statement or are the Chinese watching your every move.:biggrinQuote:

Here is video that covers the construction of lithium batteries. This guy is one of a few places that build batteries in the USA. I believe the outfit is called the Mad Scientist out of Flora Mississippi. He goes over what goes into building lithium batteries. I remember him saying condensation is the main reason batteries fail. He also mentioned a quality BMS is also important and does name the two he uses. He provides some good information. The cool thing is they repair batteries while you wait :cheers2
The Baddest Lithium Batteries On The Market!!! - YouTube
A very good article using LA and lithium batteries in parallel
Lithium-Hybrid.
I went with the heated Li time batteries for my trolling motor. If they cause my boat burn to the ground or stop working anytime soon I'll update this post. If you can afford Impulse, I'm sure they have good batteries.
my florida buddy made himself crazy overthinking, as he is wont to do, the whole thing, watching tons of youtube video's and then buying couple chinese batteries that were complete junk and then trying to get hold of anyone during chinese new year which made him crazier. Then he bought local from dealer he knew but they didn't know diddly about the units they were selling and finally got all his money back from both sources.
Their is a crappie com video of Slab coming to our rescue, lending us a spare Impulse lithium which worked great and when he called spoke directly to OWNER and got his battery solution from them with a nice discount. They are a CDC sponsor and good to know they are there to back up their product.
Personally I rarely use my TM on my fishing pontoon and just going to get a wally world unit that will take care of my needs. As I mostly prowl the docks and banks when I am ketchn.
I got a good deal with a discount on Epoch 12v 100ah batteries for my trolling motor. they have an easy to setup and use bluetooth app. I have fished for as many as 5 days trolling constantly for 4 to 6 hours and finally got below 40%. I ran several long stretches intentionally on 10 with my ultrex just to see the performance and what it would do to the % left. They are awesome.
I recommend
Want to be a little careful running Minnkota trolling motor on 10 for extended periods ( using lithium's ) as Minnkota does not recommend because of the higher voltage and possibly overheating resulting in in burning up the trolling motor.
In a series circuit, the current is the same in all elements.
I stand by my Ionic 100AH battery. Can't say enough good things about it.
Ionic 100AH batts for me.
