HC02 Battery equalizer, Works fantastic

I have (4) banks of 4 agm batteries ( 16 total batteries ). So 4 + 4 + 4 +4 12v to equal 48volts total. My solar charger charges at 48-56V but I use the banks 12V at a time ( using 2 different inverters ). So I’m draining 1 or 2 banks at a time while the other two 2-3 banks will get over charged. So I bought this to equal them all out. It’s not going to pass 100amps between batteries or anything but after 24 hours, I check the batteries and they are all perfectly equal. Couldn’t be happier for the price.
