I have been using a home made rechargable 5 cell battery battery pack, but now I am going to do a mid tank, and I need to mount my battery on the front shock tower. I bought the HPI rush battery box, and my battery packs will not fit in it. So either I just zip tie the pack to the tower (I don't really want to do this) or get a regular hump pack. But I am wondering if there is a LiPo that I can use that will fit into the ruch box??
