Dual Pro on-board Charger
Pros: I recently purchased a dual pro on-board charger for my boat. Unit is well made and has strong indicator lights (which was a problem on my old unit).
Cons: No cons noted yet
Other Thoughts: Batterystuff was priced great and delivered fast. I do have one issue though...I ended up needing to buy the extension cable for my charger, but Batterystuff didn't have it. I ended up having to but it from another source. That should not have happened, but no reflection on the charger unit.
