This model is for a 12S8P DIY Battery Pack (18650 Cells). The individual cell holders (P-Packs) will hold the cells in a brick shape allowing easy configuration for the overall battery as well as provide a stable platform to spot weld with. Each P-Pack has inlaid number, polarity, and current flow to provide a helpful reminder as you build your pack and was designed with AMS use in mind. That being said, I made sure that the model was .2mm embossed so that if you wanted to print in all one color to save time that it would still serve its purpose… just wouldnt be as pretty haha. Happy building!
