I had 4 packs. They performed alot better than expected. For the money you cant beat it. I bought them about a year ago and one set is still going strong in a aftershock conversion with a 8xl[the truck weighs 15 pounds] The other set I lost sinking my emaxx in brackish water
I own 2 4s 4800 packs and like them...my only gripe would be the open ends of the batts..dirt tends to get under the shrink wrap a little. My suggestion is to buy more wrap from them...they sell wrap as well and re wrap them concentrating on the ends. They do perform very well.
