I received two pre-production or early production samples for testing from Vapcell. I was told that they will not be generally available for several months, perhaps the end of the year. I do not know who has them in stock now or when they will.
I am testing them now because of the large number of requests I received and to let vendors know how they perform. I will retest these when full production quantities are available as Sony might make small changes to the cell’s performance before then.
The two samples of the VTC6A I tested easily outperformed the VTC6. While the VTC5A hit a tiny bit harder than the VTC6A at the start of the discharge the VTC6A outperformed the VTC5A for the rest of it, especially at higher current levels. This is a great battery.
For a 20A continuous discharge the VTC6A runs at the same temperature as the VTC6 does at 15A. Sony will probably rate the VTC6A at about 5A higher than the VTC6. This means a continuous current rating of 20A for the VTC6A with temperature-limited operation at some point above that. My preliminary estimate for the VTC6A’s current rating is 20A, up to 25A if the temperature is kept below 80°C. This can change at any time as I learn more about this cell.
The VTC6A’s I tested delivered 2892mAh and 3008mAh at 0.5A. This is a larger than typical cell-to-cell variation for Sony cells. I don’t know why. The capacity might change a bit before the cells are available in full production quantities but I am estimating the VTC6A’s rating at 2900mAh minimum and 3000mAh typical.
I have requested a copy of the datasheet but no one has it yet.
Two cells were donated for the purposes of testing by Vapcell (www.vapcelltech). 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.
