Safety Guidelines

Lithium cells should only be used with appropriate protective electronics. Mishandling the battery may result in fire or explosion.

Test Results

BAK is one of the leading manufacturers in China, known for producing high-performance cells. This is particularly crucial as cells from major manufacturers are harder to obtain and sometimes come from outdated stock, are of low quality, or even counterfeit. It’s reassuring to see well-functioning alternatives like these.

The BAK cell slightly outperforms the Molicel M50A and delivers performance comparable to the Samsung 50E. However, it falls short of the Samsung 50S, which is significantly more expensive.

According to the datasheet, the BAK cell has a maximum discharge current of 15A, but the manufacturer notes that this affects cycle life. Staying below 10A is recommended to reduce risk, extend overall cell life, and enhance performance.

Two tested cells delivered 4987mAh and 5020mAh, demonstrating good consistency for cells from a major, reputable Chinese factory. Both exceeded the minimum capacity of 4900mAh and closely approached the typical capacity of 5000mAh.

Manufacturer’s Warranty:

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

Conclusion

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