I have a couple different brands of LiPo 2S hard case packs with the same capacity. They are both different sizes and both fit into my buggy using stock battery bar/strap. A normal hard-cased 4000mah 2S LiPo pack will be the same sized as a 6 cell NiMh pack. They average 139mm x 46mm x 25mm (L x W x H). I also run some soft-cased LiPo packs and use battery spacers under the strap for a secure fit.
