18650 Battery Tail Cradle
A 78 x 46 x 33 mm bolt-on tray that holds two 18650 cells (18.4 x 65 mm) side by side on the back of a rover chassis. Three saddle ribs with 19.4 mm half-round channels locate the cells. Velcro strap slots and zip-tie slots hold them down, and the front wall has four M3 heat-set bores (4.0 mm) for mounting.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
🧩 Part of the SG90 Wheeled Serpentine Snake Robot (tail / 2S battery and servo driver bay) kit.
