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
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.

Great for batteries under 55 amp hours
Pros: I built my own all terrain mobility scooter and put this charger in it. The first one I got had a defect (wire broken where it exits charger). Battery Stuff and Pro Charging Systems were great and the exchange went very well. The scooter has 3-50 Ah batteies in series. Being able to charge the batteries independently greatly extends battery life. This charger does a very good job and the float voltage for the AGM batteries is perfect.
Cons: Don't know if this is really a con.... Pro Charging Systems chargers are repairable except for this model. You need to know that if it ever does break after the warranty, you got to get a new one.
The LED indicators are very bright making it real easy to see if the batteries are ready, even at a distance.
