Hey, guys,

I did a test to find out if soldering 18650 cells leads to a loss of capacity or not.

I tested 4 cells and used the following procedure:

1. Each cell measured 4x (capacity). So 16 tests overall

2. 2x soldered, (one solder point) and then again soldered a piece of virtual wire.

3. let it cool down

4. 4x capacity measured.

In my opinion there happens absolutly nothing.

Here are the results (blue is before soldering an red after). The error bars describes the deviation of the 4 tests:

I also documented this on YouTube (german):
