As some of you know, I am in the process of rebuilding/improving an AliExpress battery pack. One of the design details I came up with was to separate the two banks of 18650 cells with lightweight extruded greenhouse polycarbonate. See the photo below.
Originally I was thinking of creating two plenums on either side of the battery and blow air through the open passages in the polycarbonate. But another thought I had was sealing one end of each polycarbonate panel with silicone seal, filling up each channel 90% with a phase change material like (liquid) paraffin, then sealing the open ends with silicone seal.
Curious as to your thoughts on the matter. Air-cooled? or PCM-cooled?
