inexpensive portable battery charger with equalization

[sledhead]

A good buddy of mine is looking for a equalization battery charger so he can equalize his battery bank on his crappy trailer and wants to keep the charger if he ends up selling the trailer . The trailer has a Power Converter now 

Any ideas ? I have been looking but not much out there until you get to a inverter / charger for the house system

thanks   dave

What voltage?

Just go to the auto parts store and get a smart battery charger. They will automatically raise up toe 14.1 volts then taper down. When at 100%, they turn into a trickle charger. Good Luck, TomC
