Bench Test Results: Vapcell Blue K28 – 20A 2800mAh 18650…slightly exaggerated capacity, decent performer https://ift.tt/2HZpBsK

Test Report Summary: This cell is a decent performer but its capacity rating is slightly exaggerated, something often done by Vapcell.

It has a lot more voltage sag than the 30Q and VTC6 at the start of a 20A (60W) discharge but once it warms up it performs essentially the same down to about 3.1V. Below that voltage this cell can’t compete with the higher capacity 30Q and VTC6.

The two cells I tested delivered 2764mAh and 2779mAh. This is decent consistency but these cells fail to meet Vapcell’s 2800mAh rating. Since the two cells I have cannot be the lowest capacity ones in the batch I am rating the K28 at 2700mAh.

The Vapcell K28 ran slightly cooler than the Samsung 30Q and this cell’s 20A rating seems reasonable. If you can find it for less than what the 30Q and VTC6 cost you might consider giving it a try.

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

I want to work for the vaping community full time! If you feel what I do is worth a couple dollars a month and you would like early access to battery availability, battery and charger testing and news, and a say in what I test, then please consider becoming a patron and supporting my testing efforts: https://www.patreon.com/batterymooch.

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, Murata, LG, Panasonic, Molicel, 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 and you use them AT YOUR OWN RISK. Never exceed the battery’s continuous current rating and keep the plastic wrap and top insulating ring in perfect condition.

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