Current state:
I currently have some 12V AGM batteries in my FWD Fleet that are 9+ years old that I would like to replace. I already installed a 200W solar panel with a Bouge RV controller with lithium charging capability.
I currently have the Blue Sea ACR and the Atwood plug going to the truck battery.
The truck has an aftermarket alarm that has a parasitic draw that will kill the truck battery if it sits a few days w/o using. But the solar panel keeps the house batteries charged and provides a back up to the truck battery so everything is hunky dory in current state and I can leave the truck parked for days w/o worrying whether it will start or not. It fires right up.
Future state:
I purchased a 100 AH lithium battery to do the upgrade but not sure how to set up the connections.
I really only want the new lithium battery to provide backup power to the truck. I do not need the alternator to charge the house battery as the solar panel does just fine on its own.
I've read where you should not mix lithium batteries with agm which is what the truck has so not sure if I need to use a dc to dc charger between the lithium to truck battery and if I need to bypass the relay etc.
The FWC Lithium Manifesto says I can just "chuck one in there" which is what I'd really love to do but want to make sure I am not missing anything that would kill my new lithium battery.
I'd appreciate some guidance as I don't want to remove the alarm system in my truck as it has remote start and lock/unlock capabilties that come in handy.
TIA
