Pavo 20 Pro battery rubber

I advise using TPU

That's how I use it, works great for me

 

Boost Mefor support, or see my other models related with drones!

I also have minimalistic protection for Radiomaster with TPU

Different sizes, which one to take?

If you lost only one rubber like me - print standard one, it's same size

If you lost two, or for some reason want to replace two of them, use the bigger one - it should guarantee that your battery will not get hit by rotors
