For 16340 batteries they handle load very well.

Conclusion

These IMR batteries have very good performance at any load, but the capacity is, of course, not that high.
At the current time I can only rate them acceptable, because Efest is a new company, and the batteries is not from one of the big brands.



Notes and links
