Pi Zero Single 18650 Power Sled
An 84 x 62 mm base plate that holds a Raspberry Pi Zero on M2.5 standoffs (58 x 23 mm pattern) next to a slide-in sleeve for one 18650 cell (18.4 x 65 mm). The sleeve is open at both ends for the wire tabs and has a top slot for pushing the cell out. Four M3 corner holes let you bolt the whole power pack into a robot or project box.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
18650 Four-Bay Screw-Contact Test Sled
A sled that holds four 18650 cells (18.4 x 65 mm) in 19 mm open-top troughs on a 24 mm pitch, so you can test, balance or capacity-check salvaged cells without spot-welding. Each end wall takes an M3 brass heat-set insert (4.0 mm bore) on the cell axis. An M3 screw threads in to clamp the cell and make contact, with 3 mm of travel at each end. Footprint 100 x 87 mm, 20 mm tall.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
21700 Three-Cell Strap-Down Cradle
A strap-down cradle for three 21700 cells lying side by side. It's for power banks, e-bike packs and high-drain flashlight builds, where almost every printed holder is sized for 18650s. It has two 22.4 mm saddles on a 25 mm pitch, so 21.0–21.7 mm cells drop in with 2.6 mm walls between them. The open ends take cells of any length, including 76 mm protected cells. Slots for a 20 mm hook-and-loop strap and four 4.5 mm M4 holes are on a 108 x 60 mm base.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
2S 18650 Rover Battery Cradle
Twin-bore sleeve that holds a 2S pack of 18650 cells (18.4 x 65 mm) side by side on 22 mm centres. The 56 mm sleeve leaves the cell ends and nickel tabs exposed so you can wire them. Two end tabs with M3 clearance holes 66 mm apart bolt it flat to a rover chassis plate.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
AA Screw Terminal Battery Holder
A four-cell AA holder (98 x 74 x 20 mm) with snap-in open-top channels on 18 mm pitch for 14.5 x 50.5 mm cells, so you can see and swap cells without a tool. Each cell end gets a contact window plus an M3 heat-set boss (4.0 mm bore) on top of the 9 mm end wall, so brass straps and ring-lug wires bolt down with M3 screws instead of being soldered to flimsy tabs; four corner ears take M3 clearance screws for chassis mounting.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
