A unprotected 3000mAh 18650 with fairly high current.

The two cells tracks nicely and capacity do not vary much with load.


This looks like a good battery that can deliver a lot of current and it has a low internal resistance.

Thanks for another test! I really appreciate the work and time you put into this for us...have enjoyed your various reviews and used your comparator so many times and often refer friends to your site.

:slight_smile: Good

I wonder if this is the rewrap of the Samsung 30Q6-T.

Using HKJ’s battery comparator discharge graph at various discharge current, this Vapcell 3000mAh v2.0 purple is slightly better (or at least equal) to the Samsung 30Q at all discharge currents.

Comparing it to the Sony VTC6 though, the VTC6 has very slightly more capacity at low discharge currents, but at higher discharge current (7 or 10A or higher discharge current in the battery comparator), this battery has a bit less voltage sag (meaning, it performs a bit better).

Looks like a very good battery indeed. Thanks for the review!
