Welcome to ECF , but not many tanks are going to work very well with that particular setup . They are small , low mah batteries and won't really support tanks very well . You can get some CE3's or 4's and give them a go . Unless someone here knows of something else , I'm afraid your out of luck . And before long , you will be replacing those , with something bigger , and better anyway . So just use em , till you get ready to upgrade .
