New Charger
Pros: This thing is the King Kong of battery chargers and I have had a few!! The LED lights work great inside my trailer from over 40' away. I have not had a problem with it yet!! besides being dead sexy it works like a charm and it is money well spent.
Cons: The Mounting situation is the only thing that I could complain about. It has four plastic holes that could be easily tore up. This thing does have some weight to it so keep that in mind when mounting. But dont let that put you off it is well worth it.
I purchased this thing to put in my Semi trailer it is a 53' double stacker with a 8,000 lbs liftgate. I hooked this up to an Inverter and it is charging while the truck is driving. It charges four of the big Yelleow top Optima's and works like a charm. Thanks Mike Bell Bell Transport. www.belltransport.net
