Beta75 Pro frame to Mobula7 parts conversion kit

To convert a Beta75 Pro frame to work with the Mobula7 I found the best way is to trim the existing battery holder off and then use one of the ones I designed made out of TPU.
I had designed a battery holder that just slid into the existing battery holder but it was a bit over 3 grams.
I just used a pair of flush wire cutters to trim off the old connector, the pictures should explain it all.

Update: added a version of the stick battery holder that will just hold 1 battery for 1s flight.
