Balmar smart gauge and 10 hour AH testing
So this guy was selling an open box Balmar smart gauge on fleabay. They are expensive and I go by voltage to gauge my batterys by that. Well he had a make offer price so I lowballed @ $140. He didnt ...

Beware of that status gauge. You can see if it tells the truth once you do your test.
To be clear, you will get to 50% by SG and voltage readings after a certain time. So if it takes 8 hours, that is 8 x 7.5 = 60AH for 50%. So your 100% full is 120AH. Rating as new is 150AH so you are at 120/150= 80%
Same as 8 hours instead of 10, so you can just use the time to get your percentage of rated SOC.
I am thinking that gizmo is going to give the wrong answer unless it already knows what the actual AH capacity of the batteries is, and how can it know that, when you don't yet?
