I am a new Z20 owner and I have set up bank charging per recommendations in these forums. it is working like a charm. One concern I have is that in the dropping of the Soneil string charger, desulfation action is lost. anyone know of an applicable battery desulfator (60 volts nominal) that would work with the Z bikes?
I would just use the original string charger on every second or so charge
Your batteries shouldn't be going out of balance on every single charge
