Lithium batteries and new solar charger
I am replacing my 4 6V batteries I think 2 lithium, have never been impressed by the 30A PWM charger for my 600W solar, probably my fault for using 8 avg wire on a 9m run. Thinking if I get a Victron ...

Still no answer :(
So if 10v is true zero and is 100AH down for the BB 100AH battery like it says, then people are fooling themselves thinking it is really a 120AH batt so they are not really going that low all the way to zero.
no one said for sure they were using 120AH to get 100, but the tear down test on you tube indicated they were using some extra capacity so I am not sure what is realy going on, but here is the only answer that matters.
using 100% of the capacity of the battery, (from 14.1V or what ever the top 100% is again to 10V) is one cycle of the battery.
you have aproximatly 3000 cycles like this in that battery (maybe more) so if you cycle your battery twice every weekend for the rest of its life it will last you 28.8 years. another company builds ther ebattery with extra capacity so they can give a longer usage so they get 5000 ccycles that will last 48 years... does it realy matter to the average guy? the price has dropped so much you can afford to use and abuse them as they will last longer than the adverage camper will...... I know anyone over 45 the burchases a battery has a pretty good chance of passing away before the batteries do.
