A BATTERY MOOCH POST: Vapcell Gold 4000mAh 30A 21700…appears to be Samsung 40T, beats 30T for regulated

The Vapcell is identical in appearance and even a touch better in performance to the Samsung 40T’s I tested four months ago. Perhaps they tweaked the chemistry of the 40T since my test of it or the samples I tested then were a lower grade.

The Samsung 40T, and this rewrap of it, are incredible performers. They easily hit harder than any other cell available to us except the Samsung 30T and are a great choice at higher power levels. This cell and the 40T easily outperform the Sanyo NCR20700A for both regulated and unregulated devices.

While the hard hitting 30T is the king for unregulated devices the 40T and this cell beat out the 30T for high power regulated devices, delivering 8.1Wh at 30A down to 3.2V (about 3.6V when put in a charger) versus about 7.3Wh for the Samsung 30T. The Sanyo NCR20700A only delivered about 5.1Wh.

I am rating this Vapcell at 30A and 3900mAh. Its “typical” or “nominal” capacity is about 4000mAh.

I do not know who has this cell in stock or when anyone will be stocking it. Please check with your favorite vendors or Vapcell.

Two cells were donated for the purposes of testing by Vapcell (www.vapcelltech.com). Thank you!

These tests only note the estimated ratings for these batteries at the time I tested them. Any battery that is not a genuine Samsung, Sony, LG, Panasonic, or Sanyo can change at any time! This is one of the hazards of using “rewrapped” batteries or batteries from other manufacturers so carefully research any battery you are considering using before purchasing.

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage. They are not meant to be used outside of a protected battery pack. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

Any rating in the tables can change at any time as different grade cells appear on the market or we get swamped with fakes. Please, never assume that the ratings in the table are permanent and will never change! Always download the latest version before considering any cell purchase.
