Lithium batteries

Weight is a huge issue with batteries and trailers. A great many folks simply don't have the weight capacity to add a good bank of lead-acid batteries. And the battery weight is almost always mostly increased tongue weight.

That is not the case with many Class A motorhomes and some Class B/C motorhomes.

In our situation, we intentionally bought a Class C motorhome on an over-kill chassis that can handle 14,050 total lbs. while at the same time our usual fully loaded total camping weight is only around 11,800 pounds. We can carry plenty more weight but I don't want to give up gear storage volume to add more batteries.

Hence, a couple of Group 31 size 12 volt lithium batteries with a capacity of say, 400 amp hours mounted right in our present battery cabinet - instead of our current two AGM lead acid batteries with only 200 amp hours - would be just the ticket. We don't need a huge battery bank, as our motorhome is equipped with three ways of charging our battery bank as frequently as needed when drycamping without solar ... and we can always add some solar should we want to.

Perhaps someday lithium batteries will be available two ways: Weight Efficient - standard group sizes with around the same lead-acid capacities but very light, and Capacity Efficient - standard group sizes with higher than lead-acid capacities but very heavy.
