BatteryProtect 12/24V-100A - SMART get's hot!

input Voltage

output Voltage

Voltage drop

Hi! I have huge problems with my BatteryProtect 12/24V-100A SMART. For some time now, it has been getting extremely hot in operation, even if I only constantly consume arond 60-70W. The voltage drop between the input of the BatteryProtect and the output is approx. 5 volts!!! According to the thermal imaging camera, the BatteryProtect gets 56°C.
 
Something can't be right there, right? does anyone know the problem?
 
The annoying thing is that my BatteryProtect, which was still under warranty at the time, broke about 2 years ago and the replacement device seems to be causing problems again. So far I've actually always been satisfied with Victron...
