Zebralight SC700D and Molicel 21700 P42A 4200mAh 45A Battery compatibility.

It works. Still rattles but far less than a Samsung 40T.


I double wrapped my 50E and there is still plenty room left in the tube. Don’t know why they made it so wide.

I use a Samsung 50E in mine, too. I like the benefit of a few extra mAh.

A couple wraps of masking tape at the ends eliminated battery rattle.

I did the double wrap with the 40T. The issue though was that the double wrap would interfere with the positive contact for charging the cell. Had to use a magnet as a makeshift nub to make contact on the charger’s positive contact.

I think a single wrap on the Molicel will fix the rattle, or doing the suggested tape wrap.

Overall I think I’m going to use the 40T in something else and keep the Molicel for the 700D.

I don’t use the 50E as I don’t want to put solder blobs on the positive contact.
