This is a high current 18650 battery from Xtar.










The two cells tracks very nicely and has nearly constant capacity up to 15A, but they are not really suited for 30A continuous draw.















Conclusion

The batteries is a good battery with acceptable performance, but the 30A specification is a bit misleading.

Over rating the cell, or maybe using pulse rating it not only done by Xtar. It looks like it is on the raise, probably due to vapers that wants very high power.

I do not see it as a problem using pulse rating, but it must be specified that it is pulse rating and for how long pulse and preferable also a rest time or a repetition rate.

Too far compare than this one. May be, can stand discharge at 30A, is better description in the label. :shy:
