Voltage setting for Lead / Acid Battery? (1 Viewer)

[ShaKen]

I’ve a Victron SmartSolar MPPT controller in my system feeding a 100ah standard Lead / Acid Deep Cycle battery.

I noticed that my controller was dumping in 14.92V in absorption phase, which to me seems high; so.....

Q. What should be the max Voltage fed to a 12v Lead / Acid battery?

Normally 14.4v.

check the settings maybe in the mppt that it hasnt somehow switched to lithium settings

Yes normally 14.4v but it is temperature compensated so if like me you were at 6C today then 14.92 would have been fine as its 14.4v at 25C

I do have a SmartBatterySense in the system thus battery case temperature is taken into account, so that may well be the reason - with battery currently sitting at 10C.

Put the heating on in the van for a couple of hours if no change, change the settings on the regulator.
