Update: 5-25-2019 I just added another holder that will fit most 2S 450mah batteries

These are TPU battery holders for various different Whoop Frames and Battery Sizes. These battery holder are designed to fit into the frame and then not fall out so you do not lose them easily. You will need to work them though the bottom of the frame so the ends stick out either side like seen in the pictures without the batteries installed. Then just slide the batteries into the to ends (it should be a tight fit so the TPU has to stretch) an set it to the desired position.

The 2x1S Battery Holder is designed for the Beta65Pro V3 frame and two 1S 250/260/300mah stick style whoop batteries. (See pictures or 65mm orange frame drone)

The 2S Battery Holder is designed for the Beta85X (also will work on 75X or 75Pro/75Pro2) Frame and a typical whoop sized 2S 300/350/450mah battery. The adjustable version has bumps on the size to fit 2S batteries that are slightly bigger. I suggest using two small pieces of umagrip (or rubber pad) on the bottom of the frame to also help hold the battery extra securely.

The 3S Battery Holder is designed for the Beta85X (also will work on 75X or 75Pro/75Pro2) Frame and a typical whoop sized 3S 450/520mah battery. The adjustable version has bumps on the size to fit 3S batteries that are slightly bigger. I suggest using two small pieces of umagrip (or rubber pad) on the bottom of the frame to also help hold the battery extra securely.

If you have a battery that does not quite fit let me know the sizes and I can make a new holder for that size battery.

Other Uses: It also provides a small bit protection for the battery and as well as flat surface to set the drone down before taking off.
