This is arguably the most widely sold and respected 18650 form factor size cell on the market, still today. This cell is of very high quality and has a very economical price point to book-end it. This is an excellent balanced cell in terms of performance and reliability. Also this cell has a very good equilibrium with a moderate-high capacity of 2,500 mAh in energy, while having a high maximum continuous discharge/drain rating of 20 amps (Without any temperature cut involved). This cell is very stable, even when it's pushed to its max rating. This cell has about everything you could desire in a Li-Ion cell, as you can see from some of its attributes.
