would just get the imax charger the duratrax charger is not going to balance the lipos very well. You need to have a good charger for lipos that is one of the most important things. Lipos will ruin your day if you have a bad charger that causes your car to go up in smoke. But the duratrax lipo is good. I would stay away from venom lipos everyone i have owned has fried within a week or two.
