Mobula7 V4 2x1S 2s holder/adapter

I've created this model so I could quickly snap it onto my mobula7 1s in the field without any tools or modifications to the frame or the FC. Printed mine with 95A TPU. It needs to be flexible in order to snap on the frame so PLA won't work. It held up well during crashes outside, only detached itself once during a very harsh crash.

Note that in order to use this you'll need to either solder 2s bt2.0/A30 pigtails to the FC itself, or create a small adapter like I did. I like the adapter approach more since it means while flying 1s you compromise no weight for being able to fly 2s, and when flying 2s you'll only sacrifice around 0.9g for the holder and 1g for battery adapter pigtail.

I've made it big enough to fit 550mAh betafpv batteries. It re-uses the existing battery tray for one of the batteries unlike other models I've found, so that center of mass isn't greatly affected.

Pro tip: set up profiles in betaflight so that it automatically switches them when flying 1s or 2s, applying a motor limit to 2s one so that motors won't overheat. I've personally flew 23500 KV 1002 flywoo motors with 75% limit with no issues for quite some time.
