Do battery brands matter
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.

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.

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....

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.
