Whoa !

Mexico, I thought you were hooked on MegaWatt power supplies. Why the change of heart ?

Personally, I think a 50A power supply is overkill for someone with a dual 6V golf cart battery bank.

This single unit would be by far the quickest route to charge batteries as used in a stand alone position. The Megawatt intends to be a supplemental charging unit used to augment a "decent" on board converter. The WFCO is an indecent on board converter and folks who rely on a WFCO for boondocking are braver than I. If the converter does what WFCO does "best" a 400 watt Megawatt is just plain too small.

This Meanwell pumps out a minimum of 50 amperes and when you calculate a 50 percent SOC acceptance in excess of 100 amperes, suddenly 50 looks like the bare minimum. After about an hour's worth of charging charge acceptance will be falling toward the 50 amp mark but with the unit set at 14.8 volts, it's going to feed far and away more power safely than any brainless smart charger.

I chose a pair of modified Megawatts as the heart of the Borg system. Not the least of which is the fact the Borg is two Megawatts meaning backups that are totally interchangeable with one another. More modifications meant a total charger delivery in excess of 90 amperes. And a programmable timer to default from absorbsion to float whenever I wish. And utterly adjustable absorbsion and float voltage limits AND an ability to supply in excess of 40 amperes at FLOAT to eliminate psychotic needless cycling with varying hotel loads.

When a person considers it takes a wheeled charger the size of a 7,000 BTU portable air conditioner to do less than what a cigar box size Meanwell can do, the choice is pretty clear. This critter has a remote on/off switch capability and remote voltage sensing capability.

There is no one-size-fits-all answer for battery charging. It took a lot of effort from Mr Crippled here to manufacture the Borg. I certainly do not expect anyone in their right mind follow in my footsteps. The Borg has been working 24/7 for years. This is what I demanded. I am going forward with the successor of the Borg, the Hyperwatt. The Hyperwatt will have twin 56 amp Megawatts, but the float unit will use an ultra heavy duty thermistor to compensate temps from -20F to +122F
