Pleo battery pack

thingiverse

Introducing V7 of a revamped Pleo battery pack, which utilizes flat coil springs from a broken mouse reel. Cut an inch-long piece and bend it into an "M" shape to connect the batteries through the top and bottom slots. For the resistor or thermistor, insert it in the designated slot beneath the bottom plate and bend its ends for contact with the battery cells' bottoms. Secure it with glue. A small block is placed in the specified area using dip (acetone-based plastic mixture) or superglue. This updated design requires printing parts with a .2 layer height, 100% fill, and a raft/support for tower structures. Earlier versions needed tennis racket-shaped copper tape to connect thermistor legs, but V7 simplifies that process. Assemble six cells alternating orientation, tape them together, and slot the battery pack over the towers with positive and negative ends in their respective places. Fasten with screws and adjust if necessary. Note: using a 12k ohm resistor instead of a thermistor ensures proper Pleo operation; however, responsibility lies with the user for potential damage to the robot. The design is now available as separate Sketchup files for ease of use.
