This cell has “Max continuous discharge: 38A” on the wrap. While this is a bit of an overrating this is a great performing true 30A cell.
It appears to be a Samsung but it outperforms any Samsung I’ve seen in that capacity range. It might be one of the new generation cells being produced for automotive use.
While this Vapcell has a lower capacity rating than the VTC5A it holds its voltage up better at high current levels. This makes it about equal to the VTC5A in total running time down to 3.2V. The Vapcell hits a touch harder than the VTC5A at the start but the VTC5A runs for a touch longer. I’m not sure you’ll see a difference in actual use though. The Vapcell does run cooler than the VTC5A and this can help extend overall battery life when used at very high current levels.
It runs cooler than the HB6, and for a lot longer, making it a better choice than the HB6 for very high current use. This is a damn good cell!
While rated at 2000mAh, this cell only delivered 1912mAh of capacity at 0.5A down to 2.5V. I consider this the “typical” or “nominal” capacity. The rated capacity must be considered the guaranteed minimum capacity and therefore must be less than this nominal capacity. It is typically 100mAh-200mAh lower than the nominal capacity rating.
I am rating this Vapcell cell at 30A and 1800mAh.
I don’t know where this cell can be be purchased yet but vendors can contact Vapcell (www.vapcelltech.com or https://szfyte.en.alibaba.com/). The two cells that were tested were donated by Vapcell for that purpose. Thank you!
