Hey guys, I'm nearing the completion of my MMM E-maxx and I'll be using [link=http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=10310&Product_Name=Turni gy_4500mAh_3S2P_30C_LiFePo4_Pack]these LiFe batts[/link] for it but I dont know how I'm going to secure them in the stock chassis. I already ordered the traxxas extended hold downs for the emaxx but they are not even close to being enough room. I was looking at the battery trays from kershaw designs but he doesnt have the dimensions of the trays themselves, just what can fit in it lol. I did send them an email asking this question but figured I would ask around and see what other people thought as well. I did look into getting a new chassis but its just not in the cards right now. Any info or ideas would be appreciated.
