Have charged nearly 1000 cells with this and still going strong
I would have preferred solder tabs to connect wires to the holders, rather than the PC pins, but I guess that's what's available. The PC pins are a bit small to solder a big 12AWG wire, but a secure solder joint can be made. I bent the PC pins upward 90 degrees so that they stick out the sides of the holders, rather than out the bottom.
I subtracted one star because the 18650 cell fit is tight and the holders don't seem to have a maximum current rating spec.
The holders can accommodate unprotected 18650 cells like the Samsung INR18650-30Q flat top, but even then it's a bit tight. The Samsung's are about 64.5mm long. My old unprotected AW IMR18650 button top cells also fit in these holders. The protected AW 18650 cells (flat top) that I have are all too long to fit (about 67-68mm long).
The PC pins on the holders are about 0.060" wide and 0.015" thick, for a cross-sectional area of about 0.6 mm^2. That's just about the same area as 19AWG, so perhaps the cradles can take up to about 10A.
Bulgin BX0036 C-cell holders have solder tabs and PC pins. The solder tabs are rated at 20A, while the PC pins are rated for 5A. The solder tab dimensions are 0.110" wide and 0.025" thick, for a cross-sectional area of about 1.8 mm^2. That's in-between 15AWG and 14AWG, and consistent with a 20A rating. Not sure what went into the 5A rating. I can imagine that it depends on the PCB thickness, copper weight (oz/ft^2), acceptable temperature rise, etc. Using some online PCB trace calculators, 2 oz copper on a 1.5mm thick PCB can support 5A with less than a 30C rise. The required PCB trace width is less than the 0.060" width of the Saim holder's PC pin. If you connect a physical wire like a 12AWG noodle-type wire to the PC pin, perhaps you can approach the 10A estimated above. But to be conservative, I'd go with a 5A rating for these holders.
I'm using these holders as 3x18650 series battery packs. Power out is through 12AWG wire terminating in Deans Ultra plugs. I have a 3S JST-XH balance cable connected for balance charging using my hobby charger. That allows me to charge the 18650 cells in the holder, so I don't have to remove the cells for charging.
Looks good other than that.
