Screen shot of bmv712, voltage high?

Hi, I’ve got my ctek 250 set for agm battery which as I understand should be 14.7v

the bmv says 14.99v and has fluctuatedto just over 15v When charging with engine running.

is this ok or is something amiss? Thanks rob.

Charging voltage CTEK D250's temperature compensated so the voltage should be 14.7 Volts at 25 ℃. Colder means higher voltage. Delta of 10 ℃ equals 0.23 Volts. And of course there is always question of meter's accuracy - calibration?
Any difference without load?

Ah ok, I weren’t sure if the 14.7 was absolute max. But that makes sense regarding temperature. I haven’t calibrated it but I might stick a multimeter across it and see.
I just wanted to check it wasn’t a massive issue more than anything.
