Thanks for your time
It is not difficult to replace an old Univolt with the newer switched mode style chargers. One for one swap in my book, but I work with it every day. A little thought and anyone should be able to perform the replacement.
I used the Intellipower 9100
with the Charge Wizard, 65amps of smart charging.
Go to their web site and look around.
It is stone quiet unless the fan is on and the fan only comes on under very high load situations.
I noticed others have said their Switched Mode Chargers are making noise. If so, they should have it looked at. The only thing you should hear is the fan.
