Any problem running my ServoCAT from a 14.4v battery?

Thanks,

Eric

Eric,

I run 15v into my powered ground board and have a 12v regulator in my virtual mirror box to power all my gear. ? The regulator accepts 8 to 24 volts in and provides up to 10 amps at 12 volts out.

I power my ServoCAT, NUC, camera, USB hub, dew heater, Argo Navis, Telrad, fan with the regulated 12 volts.

I did run all my gear for a year or so without the regulator, but recommend regulation at 12 volts.

No problem. You can power the ServoCAT off of 11 - 16V. NOTE however other accessories, that might be connected to the PGB Power distribution rail, might not be able to handle this voltage!?

Also note that the ServoCAT has 3 internal switch mode power supplies and actually the system will run slightly more efficiently at a higher voltage (say power - less current draw which means less I^R losses in the wires). The power supplies that I sold for years were rated at 15V.?

[and if you only needed to upgrade the firmware or download parameters with the ServoCAT separated from the scope you can actually power it to do this from a standard 9V battery!]
 

You won't see 14+V out of your LFP battery. 14.4 is a reasonable (though on the high side depending on who you ask) charging voltage. As soon as you take the battery off of the charger, you'll quickly see it settle around 13.6V or less.

Even most chargers should reduce to a float voltage of 13.6V or less when the charge cycle completes.

This blog post from a manufacturer has a lot of good information:?
