[KYHAM] Manual 12V battery charger or battery conditioner?

[Tyler Allison]

Anybody in Northern Kentucky have a manual 12V battery charger or battery
conditioner I can borrow?  Im trying to equalize a bank of batteries
(6x2V=12V) and my el cheapo car battery charger isnt doing the trick.

A 100amp charger or conditioner than can handle 540ah would be best but
I'm willing to try anything.

or...does somebody know a cheap/easy way to equalize a 12V battery system?

Thanks!
