This battery case is modeled for use with the 10S5P battery sold by DIYEBOARD.COM (http://www.diyeboard.com/10s5p-18650-lithium-battery-pack-36v-10ah-360wh-p-460.html).

The mounting holes are 1/8th and should be used with standard skateboard . They’re also spaced as such to line up with the original MEEPO BOARD mounting holes (so you don’t have to drill new ones).
