Just read a few days ago that if you have lithium batteries you don't need as much Ah like you need with the other batteries. is that true
my coach has 3 8d at 245AH @20hr.
if i get lithium will i need the same amount of batteries and AH
Also Charging time
which is faster GEL/AGM or Lithium?
what are the factors that are very importantand need the AH
Love Knowledge
I can't say what batteries you have on your coach but almost 100% of the amp hours in lithium batteries can be used whereas the lifetime of other batteries suffer greatly if discharged more than 50%. Also, at 50%, lead acid, AGM and GEL batteries, the voltage drops making them useless.
I believe that lithium batteries also charge faster.
I just bought some 8d agm and now I have second taught as to if it was the right investment. I store the coach and although I talked to Owner there to keep the coach plugged in he said something like "if you want to cook your batteries be my guest".
I think the battery cooking comes in to play if you have a trailer with a converter and not one of the high $ inverter/chargers we have in our coaches. My coach has been plugged in since new and have never cooked the batteries. Now on past 5th wheels and TT with converter, yes I have cooked the batteries.
Yes, a properly programmed (that is IMPORTANT) smart charger or inverter/charger will not harm your batteries if left on 24/7.
Older technology converters-- he is correct.
It's not only older technology but even with the latest converters, you should frequently monitor the battery voltage. Our old converter started raising the voltage so we replaced it with a Progressive Dynamics unit after reading all the reviews we could find. It has been excellent and keeps both banks at about 13.15, well within their advertised maintenance/float voltage of 13.2. It's on 24/7.
This is the exact model we have and includes the wizard in the box without an additional purchase: Amazon.com: Progressive Dynamics PD9245CV Inteli-Power 9200 Series Converter/...
