This is a high current 20700 battery.











The two cells tracks fairly well and can deliver nearly 30A, I get about 3000mAh from them to 2.8V








At 30A the cells gets rather hot.















Conclusion

This battery is designed for high current and do that fairly well, but specified capacity is a bit optimistic.
