4S2P 18650 Frame-Strap Battery Box
A low-profile open-top tub for a DIY 4S2P pack of eight 18650 cells (18.4 x 65 mm) laid in two layers of two, with an internal bay of 134 x 39 x 39 mm. The outside measures 144 x 44 x 45 mm. Two 22 x 3.2 mm strap tunnels run through the 6 mm floor so velcro straps hold it to a down tube or frame triangle. There's a 16 x 10 mm main-lead notch at one end, an 8 x 6 mm balance-lead notch at the other, and four M3 heat-set columns to screw on a flat lid. It's for an e-bike, scooter or robot pack you build yourself.
Flagged: battery or DC power. Not for safety-critical use without independent engineering review.
Underboard Pedal PSU Strap Hanger
A 130 x 60 mm plate that screws to the underside of a pedalboard with four slotted #6 wood-screw holes. A 20 mm hook-and-loop strap runs through two 23 x 3.5 mm tunnels to hold any daisy-chain or isolated pedal power brick up to about 100 mm long. Raised ribs keep the brick 5 mm off the plate for airflow, clear the screw heads and stop the brick rattling loose.
