12V Lithium Iron (LiFePo4)
I've occasionally found myself in need of a small portable 12v battery. I was kind of interested in these small lightweight Non Lead Acid "jumper packs' which claim 200 CCA and also have 12v@2 amp ...

What I find interesting about the Battery tender lithium's, is that they are packaged as a regular 'carjar' at motorcycle sizes, and smaller and designed to be charged without modification to charging systems. These are obviously for weight savings and not really applicable for rv usage as such tiny capacities.
Apparently they do not have a method to prevent over discharge though.
Thoe jumper packs are likely dependent on the main battery not being fully dead, but many videos exist on U tube of v6 and v8 engines being jumped by the jumper pack alone.
I am not sure we can compare a 200 amp AGM jumperpack to a 200 amp Lithium jumper pack though. Obviously it is not strong enough for Diesel or other large high compression engines, but the existence of such a product is a step in the right direction, and part of me wants in. The other part says a 22$ agm will fulfill my current portable 12v needs.
