Li-Ion (lithium-ion) 3.6V battery cell in the 21700 form factor of the highest quality class (Grade A).
Manufacturer (brand): HENAN YICHENG YANGGUANG NEW ENERGY
This is a unique model, as it allows a constant discharge current of 3C, in a 21700 case with a capacity of 5000 mAh, which is a very good result for this price.
Our tests have shown that these cells can actually withstand a constant discharge current of 15A, and are better than Samsung INR21700 50E and EVE 21700 50E, which already at a constant current of 10A reach a temperature of 60 degrees.
Constant discharge current - up to 15A, peak - 30A.
Operating voltage: 2.8-4.2V
Resource: from 1000 cycles.
Weight: 70 g.
