Battery Equilization PS Current Requirement
What power supply current capacity would be required to equalize a single Trojan SCS 200 (Gr 27) 12V battery @ recommended 16.1 VDC?

FIVE amps REGULATED AMPS. From starting voltage to 16.0 Volts 5.0 exact amps. Any other recipe is bogus.
You need a power supply that reaches to SIXTEEN volts while maintaining exactly five amperes.
The 26 amp Megawatt will go to 15.85 volts which is close enough.
If you request it in advance, the Megawatt power supplies can be "built" to output 16.1V (at slightly lower than their rated current).

An auto parts store FIFTY WATT trouble light 12 volt bulb will throttle amperage close enough to 5.0 amps as to be good enough.
Placing a light bulb or suitable fixed resistor IN SERIES with the load, if an EXCELLENT way of current limiting any power supply that does NOT have current control. What you really want is a 3.1ohm - 3.5ohm resistor rated at about 75W. (Three 10ohm 25W resistors in parallel would be good.)
If you are going to use a non-automatic charger (which is actually better in some ways), buy a cheap digital voltage/current meter from eBay.
