that is bullshit. wire size on the charger makes no difference in final charge voltage. where do you come up with this nonsense?
hagerty1 said:With a 13S pack it puts out whatever the pack voltage is and rises with the charge cycle then drops amps to about .5 amps at 54.6V until pack is saturated then shuts down.

Attach charger through V-A meter.
Test adjustments in small steps ...
Try to keep up!dnmun said:that is bullshit. wire size on the charger makes no difference in final charge voltage. where do you come up with this nonsense?
dumun ... you're talking about some odd, off topic subject that no one else is talking about.dnmun said:you are just totally ignorant of how a charger works. at the end of charge there is only the balancing current flowing in the charging leads and it is only about 60mA so for an 18AWG wire used in chargers the voltage drop is nonexistent.
I don't know how to post pictures on here. I thought the link would take you to pictures??? No ???dnmun said:measure the output voltage in front of the relay. you did not post up a picture here, just in the hosted site. post up some VGA pictures of the backside. here.
hagerty1 said:Here I am showing how little I know. When I connect the charger to the pack that I have drained to below the 54V
I assume I am to connect the charger to the Volt amp meter, run the charge current through this meter to the pack.
read the meter voltage and adjust pot to come up to 59V? It seems when connected to a pack I always seem to be reading the pack voltage not the charger voltage. I'll check again. Also when I adjust the output voltage up to 59V does this affect what the chargers sees as back voltage.....my name for what charger sees to know the pack is at the stage where amperage is reduced and finally that pack is fully charged ? P.S. I am running standard charger lead wire.
And I would think that @ 3.5A line loss would be minimal anyway on 2 feet of wire. It looks to be 16ga.
Can I:
1) Remove the pot as is from the factory and measure it's resistance value
2) Put pot back and adjust up to 59V
3) Remove adjusted pot and measure it's resistance value
4) Buy two fixed resistors and a DPDT switch make one selection be 54V and other selection 59V basically making the charger a 13/14S depending on switch position?????
Test Ohm value between leg positions of RS1 or RS2.hagerty1 said:
Which is the functionally the same, on your supposed point, as what I just said.dnmun said:you are just totally ignorant of how a charger works. at the end of charge there is only the balancing current flowing in the charging leads and it is only about 60mA so for an 18AWG wire used in chargers the voltage drop is nonexistent.
