i was looking at these and they sound pretty good thier lithium iron phosphate batteries and can be made into enough cells for automotive applications, long story short they are alot better sounding than lead acid batteries
-lighter
-smaller
-80% dishcharge vs 50% normal
-can be fast charged
-more energy
-safer
-more vibration resistant
-maintains output voltage until depleted,then has a alarm, you reset alarm and still enough to then start car
so on so on
just wondering if anyone has knowledge or installed these, mounting difficulties, costs and reliability
