150 watt DC to DC boost converter

One single battery demands 5 amperes Bumpy. Five amperes charge at the start.

Five amperes at the finish. No starting at 35 amps and finishing at 1

This is HARD to do unless some gizmos are used.

A charging source voltage limited to 16.0 volts is demanded.

A combination of gizmos that will develop 5 amps CONSTANT CURRENT is demanded. Five amps per 100 amp hour capacity battery.

By using a charger a converter, PLUS an adjustable 150 watt DC to DC gizmo called a BOOST converter this allows the voltage to be set to 16 MAXIMUM LIMIT. Or any other voltage. Read Landy's report.

NEXT! The current flow the amperage MUST BE CONTROLLED almost exactly. In the case of one battery, to 5 amperes. All dependent on size of the battery in the case of 2 L16 batteries rated at 320 amp hours the equalization formula calls for 16 amps constant current.

A FIFTY WATT 12 Volt light bulb at 15 volts passes 5 amperes of current. No more, no less. It's the restriction of the filament that REGULATES amperage. It's a simple yet effective CURRENT regulator. Five amps.

By connecting the LIGHT BULB between the DC to DC booster and setting the booster voltage to 16.0 a PERFECT equalization machine is created AND IT IS DIRT CHEAP and my 13-year old grand daughter can set one up.

Pros in the battery business USED TO HAVE been forced to spend THOUSANDS OF DOLLARS to get a machine that would do this. Of course professional machines could equalize 10 or 12 batteries at a time.

Batteries are FUSSY. They demand to be treated correctly.

The US Navy and Exide and Gould came up with an equalization formula for Pacific Fleet US submarines in WW 2. The formula was since adopted by the Battery Council International. The formula works. Lives depended on it.

Then Chief Warrant Officer Thomas David, of Mare island Naval Station explained this to a 12-year old named me in 1958. Even back then I was a nerd. On hand was an engineer tech rep from Exide. I got the tour of a lifetime aboard one of the last battery submarines undergoing refit. I more than think this forever affected me and I gravitated toward batteries and charging and maintenance for the last 50+ years.

The 16.0 volt, 5% of total amp hour formula is magic IMHO. I've tried screwing around with it but there were always shortcomings with using other values in this electrochemical recipe. The original formula will recover a battery when other methods fail. A thousand trials of pulse frequency and amplitude so call pulse desulfation FAILED to come up with better results than the original formula. I spent a lot of money, tens of thousands of dollars chasing ghosts. If it had worked I stood to make a lot of money. it did not work and I will be damned to engage myself in deception. Yes it is a flaw in character these days. Sue me.

I hope this helps because I have only and I will only open this up in public this one time.

Some of us have similar stories. I guess I was 8 or 9 years old, and was fascinated by electricity also. Such that one Saturday, my father and I went downtown in Los Angeles, to an electrical surplus store. Out of that trip came a hand crank generator, probably from an old Ma Bell telephone. Added some zip cord, a A19 porcelain light fixture and a tiny 7 watt 120 V night light, all bolted on to a piece of tongue and groove starter board, laying around.

I always showed it off to my friends, let them crank away, you could see the light get brighter the faster you cranked, and you could see the cycles in the light pulsing from the AC current not even being close to 32 cycles per second, where the eye no longer can perceive the wave forms switching.

Of course, I always encouraged them to touch the terminals on the generator, asking them to check to see if the screws were loose, and give the handle a whirl. The results were hilarious! As we got older, the tough guys would hold on to see how long and how much they could take before enough was enough. Good clean fun, those days back in the late 1960's.

Ooops, I stand corrected, it was a Magneto... this is the unit.
