150 watt DC to DC boost converter
Back in my cheapowatt PSU days, I wanted to be able to do 16 volts for EQ cycles as the cheapowatt maxed out at 15.27. But then, I smoked the unregulated cheapowatt. It was rated for 350 watts and...

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.
