Does mini 12V DC diaphram water pumps like this get really hot after running for 5 min?
I'm trying to use it as a water pump for my aquarium. I'm using a 6V 4.5AH battery with a DC step up convertor to power the pump. After about 5 minutes it gets really hot. Is this expected?
So does it stay 60-70 C the whole time or does it go beyond that after a while ? Also, have you tried running it continously for like 20 or 30 minutes by any chance?
