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.
