How to Keep Lithium Battery on Camper Charged from Truck Alternator

Question

Question:

Hello I have a GMC truck that has a 150amp alternator installed and Im about to install a 100ah Lithium battery on my RV. The truck provides a charge circuit through the 7 pin plug to the trailer. I was told that with this set up using the trucks alternator will burn it out because the lithium battery will draw a large amount of current. Im not about to charge up a completely dead battery but maybe just to top it off while driving. Would the truck wires be too small for current to the battery? Will this harm my alternator? Thanks

If you have an alternative way to adequately charge your new lithium battery on your RV when it is not in transit, the amperage drop due to the lower gauge wires on your won't really matter and will still provide you with a sufficient trickle charge from your alternator; this also will not harm your alternator in doing this.

With that being said, if you don't have a sufficient charging source for this battery, you'll need to use something like the RedArc Manager30 Battery Manager # RED88FR to charge this lithium battery from your truck's alternator. This is a premium, state of the art battery management system that will charge and maintain the battery on your RV/Camper and is designed to work with a variety of battery types (including lithium).

The Battery Manager30 # RED88FR will correct the amp loss due to the smaller gauge wires on your truck's 7 way to allow for proper charging on the lithium battery and can also be connected to AC and Solar power sources, in addition to DC power. The Battery Manager30 operates like 6 products in 1 - auxiliary battery charger, 110-volt charger, solar regulator, battery isolator, load disconnect controller, and remote battery monitor and is the ultimate is RV/Camper power solutions.

6 gauge wire does translate to 13.3 mm and the nearest cable size of 16 mm. The #RED88FR states it can handle up to a 10 mm2 wire which is actually 7 gauge so that would be the max wire gauge to use.
