This Battery holder is designed to mount under the donkey car chassis and hold one
Anker Astro E1 battery. Included in the kit is one 3D Printed battery holder and two cable ties. If you want a nice right angle USB cable it can be purchased separately here.
Note, this uses the same screw holes as the servo driver, so unless you are using the new Donkey Car Hat, or have some other solution for driving the servo and ESC
