This Is Plan For My Own Battery CHARGER

NinerBikes, observation is right on the money. But the absolute fastest charge protocol is not a 100% of the time regimen. The power supplies can be tweaked with the adjustable potentiometers. I am going to find a savvy tech with excellent vision and rock steady younger hands and replace these pots with 2-watt 3 turn 2K pots that have shafts that can have a knob with pointer screwed on.

Scenario
Hotel room. BiPAP and LED reading light. Battery. Lights go out for 4 hours at night. Charger will be plugged in, maintenance charge going. Lights come back on for a hour or so. Power supplies are set at full acceptance voltage but rational for the circumstances 14.4 volts. The timer has to be cranked to 12-hours, I think I can remember to do that before switching off the reading light. The BiPAP draws more then 4 amperes, the reading light an amp or two. The Fantastic Fan around three amperes.

14.4 volts is RV alternator charging regulator set point. If you have an issue with a 14.4 volt setting go argue with your motorhome or tow pickup's charging system.

A higher than 14.4 volt setting is for TOP CHARGING. This is where the 2 ampere 3 turn pots come in.

Remember and this is IMPORTANT.........With a power supply, you set the VOLTAGE without being connected to a battery. With built-in gauges, this takes what (?) 2.7 seconds?

They make current limiting modules that re adjustable. They cannot handle a lot of current, but they can handle ENOUGH amperage to satisfy equalization. Constant current until three or four tenths less than 16.0 volts. Then current tapers down because charge acceptance become very limited. Natural electro-chemical reaction.

This unit MAY penalize battery life by 5% or most probably <5%

Most of the Mexican fishermen go out at night and use 50W incandescent lighting. Their 20-minute run back to the beach does not recharge their group 27 battery. Jesus is going to charge them 30 pesos, and it's a 100 meter walk from their lancha to the enramada. 300 pesos a day is better than a kick in the butt.
