Charging voltage for T-105s
Continuing my quest to learn everything I can about batteries and charging... Moved on from the group 24 Interstate, may mess with it more later. Also put the hydrometer with the floating balls whe...

Leave OUTPUT WIRES disconnected
Connect to power source. Power source must NOT be less than one volt different than intended load voltage - no charging 14.7 volts from 14.0 source volts supply. 16 volts meets that criteria yes/no?
TOP CHARGING voltage limit is 15.0 volts. Best to rob converter when at float. Will it stay floating or go nuts? BIGBEETCH with converters, why does the load decide the voltage? Doesn't the battery have it's say? STOOOOOOOOOOPID!!!

With power going in and output disconnected set voltage. The OTHER pot is the amperage limiter.
Input power switched off, connect to load, observing polarity. Connect to source observing polarity.
Switch on
Amperage is way high
You goofed. Twist the pot screw back
5% amperage of total amp hours is correct for both equalization and top charging. There is a one volt limit difference.
A TEN AMP INPUT AND OUTPUT MAX LIMIT can handle a BUCKER to drop voltage from 14.0 whatever to exactly half that used in a six cell battery when zapping a three cell battery.
No need to slap three perfectly good cells around because 15-16 volts is mandatory. Top charging only the cells that have misbehaved is necessary. Hence three cells, six volts for golf car. L-16's need 15+ amps so they can take it directly on the chin with a big charger. I slap my 2-volt cells around with an 80 lb transformer. Winding as fat as a pencil. 160-amps charge rate. Anyway a 12 to 6 is done with a robust BUCKER. Amperage limit through a 100 watt bulb or two in parallel.
One battery to another, think of Robbing Peter to pay Paul. If Peter gets enough allowance, it doesn't matter. Otherwise it's a 5% net sum loss.
DIVIDE VOLTAGE VALUES EXACTLY IN HALF
FOR THREE CELL EQUALIZATION AND TOP CHARGING
