Thanks everyone. I have another question. What cables would yall use to hook
http://www.bestconverter.com/Boondo...ower-ConverterCharger_p_585.html#.VR1__XP0CBY
up to a 155ah AGM battery? (Vmax)
And with what end connectors?
The output terminals on the Boondocker cannot accept wire much thicker than 4awg.
My buddy ordered a 100 amp adjustable model, it was only 75 amps. We took 0 gauge wiring and removed enough stranding then tinned it, so that it would fit the output terminals of the boondocker.
With the adjustable voltage model, voltage drop on the wiring leading to the battery is less of an issue, as you can just bump up the voltage to compensate. However the voltmeter on the boondocker itself is representative of the voltage at the output terminals, not the battery terminals.
The thicker the cabling the more representative the boondocker's voltmeter will be to actual battery voltage.
With ~ 4 feet of quality 0 gauge cabling , one way, at 75 amps, the voltage drop was about 0.1 volts.
Get thick walled ring terminals on one end of whatever gauge you choose, and leave the other end with no termination as you will have to remove some insulation, and some stranding if thicker than 4awg, to stuff in the boondocker output terminals, then tighten the set screws on the stranded wiring. Be sure to tighten it again after the initial flattening of the stranding.
The ideal thickness of cabling you need is really dependent on the distance between converter and battery, but I would not go thinner than 4awg just so the voltmeter on the boondocker itself is more accurate as to actual battery voltage.
I hope you are aware this adjustable model is not automatic and has no charging stages. One needs to manually turn off the charger, or lower the voltage when the battery is full, or it can overcharge.
An Ammeter will be required to determine when the AGM battery is fully charged. when it cannot accept more than ~0.6 amps to be held at 14.5v, then it is near full charge.
I do not know the exact manufacturer recommended charge profile for that AGM. They all vary to some degree.
