Lithium batteries read before you buy

Ok I know you have heard about lithium batteries, how great they are, well don’t believe all you read, first if you put lithium batteries in your RV and you don’t change your charging system you will ruin your batteries in less than a week. Also know that the alternator on your motor home will ruin the batteries as it’s not design to charge the lithiums . so if you’re going to go lithium be certain you change your RV charging system to accommodate these batteries. Otherwise you will spend a lot money of money for nothing.
