Hi,I was toying with my charge voltages. I wanted to try 15.4. When I set 15.4 on the remote it did not get above 14.7 volts. The bank was fairly full so it was only doing between 8 and 10 amps of charging.Does anyone know the maximum dc output voltage?

It may have been limiting due to temperature. I know those will do well over that voltage for equalization.

Hi,The banks were at 19.5 C, so I think it is not temperature related.

If your battery is at or near charge capacity of 14v, your voltage will be regulated down from 15.4volts. If your battery was sitting at a lower capacity such as 10volts when you would see higher charging output voltage. This can usually be confirmed by using a volt meter while briefly disconnecting the positive lead from the charging source simulating a fully discharged battery. This would command 15.4v max charge. Running the charger like this for an extended time could cause damage.

Try 14.9 next time you run them down a bit. Is there a second limitation by battery type etc? Maybe reduce the amp rating to 50% of max.

time2roll,They were only charging at 9 amps.I'm using the "custom" setting on the remote.

I think we all assumed you were setting bulk/absorption.
I did post that there must be some other limit.

So that I can do a recovery on the AGM's when that becomes needed. At 77 f (25 c) lifeline suggests recovery voltage for 8 hours @ 15.48 volts.

Did you look at using the equalization function? You can set voltage and hours, then you hold down the charger button for 5 seconds while in float and it will do the equalization charger, even had a reminder in days that can be setup.

Hi jharrel,

Thanks for that information on the equalize function.

The nice thing about Magnum, is the Custom Battery settings.
Once you ID the specific battery charge, you use the custom mode.
Next step will be Lithium - Magnum makes it very easy to setup.
