BatteryTabs - Velcro(TM) Replacement
#1
Run out of velcro?  Got a 3D printer?  Then have I got a deal for you!

BatteryTabs!  The handy dandy button "fastener" to keep your lipo from sliding around on your quad.

No really, I actually came up with the button part for my latest micro quad: http://intofpv.com/t-mxq-105-fpv-quad-printable .  It already had the holes in the frame, so I made buttons to match to glue to the battery.  It worked so well, I designed a set - male/female for general use.  The files included provide for 1x2 or 2x2 but the openscad files are also included so you can make any size you want.  Note: you still need to use a strap or a rubberband, this just keeps them from easily sliding out.

      

By the way, 1 of the button tabs pictured above weighs <0.2 grams - I'm guessing the matching hole tab will weigh about the same.

Very cool idea! does the battery actually stay on the frame even when you turn it up side down?

do you double sided tape the tab on the battery?

No, I still have to use a rubberband (it's a snug fit, but not a "snap" fit). It does keep in place though.  If a crash causes the rubber band to pop off, the battery would probably dislodge too.

I used Welder brand adhesive (a foam-safe contact cement), but some foam-safe CA should work OK too (or thinly-spreaded epoxy).
