Need new converter: 14.4v or 14.8v?
I need to replace my Iota converter and have been considering the Progressive Dynamics 9245 converter. I have noted there are 2 models: one that goes to 14.4 v in boost and another that goes to 14.8v...

Start at say 12.38 O.K.?
Check the time, the clock.
Introduce 14.8 volts to the battery
Check occasionally to see when light bubbling occurs
Oooooo, three hours twenty five minutes (?) Write it down
Oooooo, start at twelve point zero volts. Four hours forty five minutes. Scribble.
Oooooo, twelve point five five volts, charge and write.
Twist the wind up timer and walk away. The generator makes a loud enough surge when the load is removed, but a kitchen timer is handy too.
Default to float when the battery charge amperage reaches "Voltage X" 13.2 is NOT DESIRABLE for generator float charging. 14.0 volts is desirable. You can run a generator 24 hours for days at 14.0 and not hurt the batteries. At 14.0 volts rather than 13.2 the batteries will absorb charge much much faster than they will at 13.2 volts.
Too high voltage? Go argue with your vehicle's alternator voltage regulator.
This recipe changes utterly when connected to power posts for long periods of time. Chargers are made for Power Pole Princess charging. Why? Because the designers can cheat and get away with murder without consequences.
It's boondocking that tests the battery charging wisdom of RV owners. REALLY smart owners, charge using far less generator run time and spent five minutes a day adjusting a wind up timer to their needs.
I much prefer hauling far less lead around but utilizing more capacity and not wasting 30% capacity and promoting sulfation. But that's me.
BTW The BORG is a Boondocker's Dream come true. I ran it connected to a FOUR HUNDRED WATT generator with BORG voltage dialed back. Got 26-amps before it started to bog down. Set the timer for four and a half hours with a finish voltage of 14.8
I REVERSED the roles of the Megawatts. The primary had to be dialed back to 13.34 to not bog the generator during the high amp phase of the charging protocol. When the timer reached zero, the secondary MEGAWATT took over set at 14.8. The generator coughed but struggled to it's feet.
Yeah, like an integrated circuit is going to do THAT!
And yes, solar helps. But creating a solar oven out of a rig doesn't.
