This is what I am looking for in a battery charger for my 24 volt pack of 4 18 amp/hour odyssey batteries, wired 2 parallel then in series. I will use 2 of these chargers and they will be permanently attached to my bike.
this company has a nice links page
I found this company
They list the 12 volt 12 amp charger, I will get with them tomorrow and find out if I can finally place my order, I have been down a week it seems.
