XLH Xinlehong RC Q901 battery adapter

Here is an adapter in order to carry a bigger LIPO battery. It is designed for the aliexpress 83mm LIPO battery hereunder, but will still be better than nothing for other sizes : https://fr.aliexpress.com/item/4000165475243.html It is actually a 2600/2700Mah LIPO battery, I recommend it for the weight/price. You can use the Fusion 360 file to change the dimensions. I had to reinforce the design before sharing it with you, my first design broke after some shocks. I used PLA, it would be better to use PETG or ABS. It need supports but it is really easy to print anyway. Use 4 perimeters and 50% infill.
