float voltage

hi

They will be put in storage fully charged.

The 4 jars will all be tied together. They will start (I think) at 14.4 for two hours if the voltage is down. The next step is float @ 13.2.

The only parasitic load will be the Blue Sky Charge controller.

Hi Don

For me the Lifeline manual dictates what voltages and what temperature for the different charging regimes and the only time I can't get the controller to agree is in extreme temps. At that point in storage I'll either set it manually or disconnect for the duration of the extreme weather. I am new to AGM's so following the manual is the best I can do.

Are you setting the float there to maintain your second bank?

The charging perimeters for the AGM can be plus or minus .25 volts without any issues. What most sellers and even the manufacturers usually don't tell you is that an AGM must be charged to 100% every time it is discharged and recharged. Every time you don't do that, you shorten the life of the battery. I often have been asked to troubleshoot AGM batteries that are 1 year old or less and will no longer hold a charge or will discharge in a short period of time. In almost every case it was due to improper charging and the manufacturer will not cover the battery under warranty. Sometimes the seller will take them back and sometimes they won't. If the battery is brought up to 13.8 and then maintained at 13.2 for a short period of time, the damage is lessened. If it's only brought up to 13.2 in the charging cycle, it isn't going to be fully charged. Chuck
