bestconverter finally got back to me and confirmed that there is no auto desulfation or manual control with the BD 1255 MBA 55 Amp 4-Stage Main Board Replacement. The price is great on these, but I want a smart charger and something with more control.
Instead they recommended the
wildkat powered by progressive dynamics.
Looks like you mount the remote pendant somewhere more accessible which gives you more control. It claims to be a true, smart 4 stage charger, which would beat the **** out of my single stage. Anyone have any experience with these???
