Hey guys,
This will probably be the first time I attempt to make a pack for an airsoft. From what I read, they need a draw of 20a and 25a for continuous draw. It will be a butterfly pack with at least 1 cell on each side.
It's going to be two pairs of series and then those pairs will be wired parallel. I won't be soldering the cells to each other. Instead, I will be making a plastic cylinder with contact springs on both ends. I will then solder both pairs of series into a parallel butterfly pack.
When I wire them in that fashion, is the 25a draw split between all the cells or do each individual cell have the same draw @ 25a? I've looked around the only 18650 cells I could find is rated at 20a continuous.
