Just a small note, i bought the battery for the offroad 250 for mine because I was stranded and needed one ASAP. It was all walmart had (also pretty cheap). Its smaller (shorter, but otherwise fit) and weaker than the default one, but I have run in to zero issues. Going strong 6 months later. It probably wouldnt be able to run as many accessories... but I dont have any so thats fine lol.
