Do battery brands matter
Well to me the warranty is what matters along with a brands reputation
This is why I bought Impulse Lithium.Quote:

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.Quote:

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)Quote:

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 constantQuote:

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.Quote:

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.Quote:

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/#post4440524Quote:

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:

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.
No inside info, just been watching the prices and number of companies entering the fray recently. Although, I did stay at a Holiday Inn last night! :RoflQuote:

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.
