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.
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.
