After lurking for a few months around the forum, I have learned much and seen the incredible knowledge, technical skills and impressive battery builds of forum members. These have largely been purpose-built and size-constrained, and thus "one-offs", primarily due to their locations (yachts, RVs, etc). These builds have been time-consuming and labor-intensive. My interest is a bit different, as I await delivery of my eight EVE 280AH cells.
My goal is to build a DIY Modular, Scalable, Reconfigurable, and Serviceable system. With demand surging for battery systems and Value-Added Resellers (VARs) springing up worldwide, DIYers have distinct advantages. I will be one of them. While Zzyzx Ink will be my VAR to design / build my modules, customer Zzyzx (currently on vacation) will do the energy audit and configure the system.
Phase 1 for Zzyzx Ink is to design a 12v LiFePO4 battery module, capable of quick and easy assembly, duplication, configuration and tear-down for repair. One of those many VARs . . . Seplos . . . has a 48v kit, BUT is using a "plastic holder" to hold the cells together. It is this plastic holder that I think can be redesigned and produced for use by those forum members interested in a 12v (or whatever size) battery "building block".
The plastic holder between cells is the common part, requiring only the end plates to be different. If you view the video, take note of the plastic "fingers" on the four sides. When two holders contain a single cell, the fingers touch (under no real compression using tape). Consider making each finger length shorter by a couple of millimeters (or whatever), such as when the "all thread" rods are connected to the end plates and tightened (12-14psi), the fingers again touch, indicating sufficient compression.
In any event, I am interested in collaborating with those forum members with similar interests. What say you?
