Blue Smart Charger IP65 12/15 low voltage and current. FIRMWARE BUG

Searching the forums I see many people with the same issue. Their IP65 chargers do not work. They get go straight to absorption, will not charge above 1 amp, will not raise voltage. Voltage actually goes down and battery dies! (because load on battery is using more than 1 amp and charger will not feed more than 1 amp). This is a 15 amp charger. What is going on?

I have messed with the settings. Tried power supply mode (changes nothing). Disable recovery mode, max recondition duration to zero minutes, fiddle with voltage settings. Nothing has any effect.

One time the charger said it was in float mode but the voltage was only 11.5V. Why would it think that is acceptable float voltage?

Frustrating because half the time, the charger works. Half the time it doesnt. Are these chargers not meant to be used with a load on the battery? Are they just meant to trickle charge parked cars? I love Victron gear because it’s so reliable but I’m at a loss trying to find a decent Victron AC-DC charger. Seems like the other versions 22/43/67 often have the same issues.

Your firmware is buggy. Please fix it.

PS: Also what is with the stupid tag selector in this post form?
