2.5 and tires are bald after 3 months. Our loads are not great we haul a couple riding mowers and 21" and trimmers blowers etc.
What style controller are you using? I use a proportionate controler (prodigy p2). I set the max voltage at 4.2 and with normal driving don't really notice the trailer back there. It doesn't push or pull on the truck. If hauling mulch I may turn it up some to help with double the weight. If you are using a cheap on/off controller it would be best to get a better on and save some brake and tire wear.
