A little note on specs
Camping world sells exide 
The Edge agm dual purpose sells for $199 and are spected at 120 minutes RC at 25 amps
The 12flx500 batteries I bought
Spec at 48 amps for 120 minutes
And
22 amps for 300 minutes
15 amps for 480 minutes that's 8 hours
An 8 hour capacity of 119 amp hrs , 8 hours discharge not 20 hours
The 20 Hr capacity will be much higher, anyone know how to calculate/extrapolate that from this info
Float voltage is 13.62 at 77°F
Charge voltage and amps is 'undeclared'
Hoping to get these installed today
