Hi guys, I'm new here.

I've a 24VDC power supply and I'm having issues only in the last 2 months with Victron Battery Protection 65.

I've several that work 4 or 5 times with turning the system off and then they fail when powered back on.

Some say E4. But it can't be an over voltage as its powered from batteries.

Others when programming they start to count up and when the get to around 3 or 4 on the display they fade out and don't work after that.

Is there a bad batch? Would the smart battery protection be better?

Unfortunately because of the power supply size the larger BP won't fit.

Think so far I've 18 out of 24 that fail.

Thanks in advance.
