Li-Ion 21700 Cell Spacers: 2x1 to 12x3
Description
These are 21700 cell spacers for making battery packs. The sizes are 2x1, 2x2, 3x1, 3x2, 3x3, 4x1, 4x2, 4x3, 5x1, 5x2, 5x3, 6x1, 6x2, 6x3, 7x1, 7x2, 7x3, 8x1, 8x2, 8x3, 9x1, 9x2, 9x3, 10x1, 10x2, 10x3, 11x1, 11x2, 11x3, 12x1, 12x2, 12x3. These should satiate the needs of most R/C aircraft battery builds. Once the cells are fitted in the spacers, spot-weld nickel strips to the terminals in the desired series-parallel configuration, solder on the power lead, and apply shrink wrap around the battery to insulate the terminals.
