Safety of Use

Lithium cells can only be used with appropriate protective electronics. Improper handling of the battery can lead to fire or explosion.

Test Results

BAK is one of the larger, recognized manufacturers in China, and its cells are characterized by good performance. This is important because cells from the largest manufacturers are harder to obtain, and sometimes come from outdated stock, are of low quality, or even counterfeit. It's good to see well-performing alternatives like these.

The BAK cell performs slightly better than the Molicel M50A and achieves performance comparable to the Samsung 50E. However, it does not match the Samsung 50S, but that cell is significantly more expensive.

According to the datasheet, the BAK cell has a maximum continuous discharge current of 15A, however, the manufacturer notes that this affects cycle life. We recommend staying below 10A to reduce risk, increase the overall lifespan of the cell, and improve its performance.

The two tested cells delivered 4987mAh and 5020mAh respectively. This is quite good consistency for cells coming from one of the large, recognized Chinese factories. Both cells exceeded the minimum capacity of 4900mAh and reached a value close to the typical capacity of 5000mAh.

Manufacturer's Warranty:

The manufacturer offers a 2-year warranty on BAK N21700CG-50 cells, ensuring repair or replacement of the product in case of any issues. For warranty claims, contact the store to arrange for a courier to pick up the product from your home.

Summary

BAK Battery is a reliable partner in the world of battery technology. N21700CG-50 cells are an ideal choice for manufacturers seeking top-level quality and performance.
