I'm amazed at the number of variety of custom enclosures made or already made ones used. Its hard to have a single enclosure that suits every ones build. I suppose the most determining factor on enclosure size is dictated by battery choice. When I made my enclosure, the size had to be able to fit in three 3S 5000mAh batteries and other related electronics. I've been slowing amassing parts for my other builds including the batteries I'll be using ( 8000mAh 4s 30c, 5800mAh 3s 30c,10000mAh 4s 10c). Decided to test fit these batteries in my current set-up and was amazed they all fit except the 10000mAh batteries. I've already thought out a modification to my lid. Its nice to have an enclosure that enables you to use different battery options. Looks like I've got some testing to do with these other batteries.
