It's amazing how technology has advanced to make it possible for us to stay connected even in the most remote areas. To answer your question, yes, it is possible and highly recommended to upgrade your camper's lead acid battery with a Lithium Iron Phosphate (LiFePO4) battery. Not only will this provide you with a lighter and more efficient energy source, but it will also give you increased capacity for longer-lasting usage. Based on the documents attached by our fellow Quora user, I would highly recommend looking into the 12V 300AH Lithium Ion Battery offered by the Lithium Battery Company. This specific battery has impressive specifications such as a nominal voltage of 12.8 V, energy of 3840 Wh, efficiency of 99%, and maximum discharge current of 100 A. With this kind of power, you can rest assured that your "Ham Shack" setup will run smoothly without any issues. However, there are some things to consider before making the switch from lead acid batteries to lithium batteries. Since lithium batteries have different charging requirements compared to traditional lead acid batteries, it is important to also upgrade your existing solar charge controller when switching over. Additionally, since you mentioned wanting an isolated power system between your camper and truck batteries while in use, it would be wise to invest in a battery isolator as well. This device ensures that each set of batteries remains separate while still allowing them to charge properly without draining each other. In conclusion, upgrading your camper's battery from lead acid to lithium is definitely a smart move in terms of efficiency, weight reduction, and increased capacity. Happy camping! -Nathan Re: Battery Charging When your truck is running, the alternator produces electricity which is used to power your truck and charge its starting battery. However, the process of charging the house battery is a bit different. Generally speaking, most modern trucks do not have an auxiliary battery charger built in for charging their house batteries. Instead, they rely on a "leeching" method where the house battery draws from the starting battery while driving. This means that as long as your starting battery has enough energy to start your truck after powering any accessories or electronics you may be using, it should also have enough energy left over to trickle charge your house battery. However, this method can sometimes cause issues if you're draining both batteries at an equal rate (for example if you are using a lot of electronics in the camper while driving). In these cases, it's always best to use a separate charger specifically designed for AGM batteries before connecting them to ensure proper charging. Now let's talk about plugging in at campgrounds. When you plug into 110v shore power at a campground with an AC-DC converter (also known as an "inverter"), it converts the 110v AC power into 12v DC power before reaching your camper's electrical system and ultimately charging both your truck starting battery and house AGM battery through their respective chargers. As for switching from a traditional lead-acid house battery to an AGM one, there shouldn't be much difference in terms of how they are charged by your factory-installed system. Most modern systems can handle both types of batteries without any modifications necessary. However, before making any changes it would still be wise to consult with someone who knows more about the specifics of your particular setup just to be sure. Make sure to keep an eye on your battery levels while driving and use a separate charger when necessary to ensure proper charging. And don't worry about causing any harm to your new AGM battery, as long as it is being charged correctly it should last you for many trips to come. Safe travels!
