Yes. The exact voltage you want is specified by the battery manufacture and is dependent on temperature. But 54 volts is the nominal float voltage for the average 48 volt battery.

Yeah, these SyncInjectors can take up to 56VDC, and it’s an Eltek with a floating ground so we’re able to put out 48vdc. Just to verify that I’m doing +48 if I put my multimeter on, red to red, and back to black I’m reading +53.98VDC which is as expected for +48, right?

I'm assuming you are using a DC-DC converter to convert your -48VDC down to 24V for the SyncInjectors handling the FSK? Also, your rectifier is probably -48VDC, not 48VDC.

This powers 4 Syncinjectors and 2 Netonix. There is a mix of 450 and FSK APs in each of those Syncinjectors. When we powered back up 6 of the 6 FSK wont establish eth link with the Netonix, all the 450 are fine. Ideas? Tower climber en route but I'm stumped. TIA Thanks, `S --- Sent mobile, typed by thumbs.
