This is a high capacity high current battery










The two cells has very good tracking and only a minor capacity loss when the current is increased.















Conclusion

There are cells with higher voltage at high current, but none other with this much capacity.
With a Panasonic cell inside it is a very good battery, that can deliver a lot of current.

Another great review, thanks HKJ.

Does this cell have the Panasonic NCR 18650PF inside?

Yes.

Thanks HKJ,

Panasonic NCR18650PF 4,2V is the best cell for single 18650 nanjg amc7134 drivers. And this one is protected. So it is probably unbeatable battery in performance and safety. Sanyo UR2600FM (FT) is small crying baby comparing to this beast delivering much less current than NCR2900PF (IMHO).

Where did you get that idea from?

So it is not protected? My apologize... I tough it was protected cell...

When I put "NA" in "PCB protection trip current" it is an unprotected cell.

With most batteries you can also see it on the batteries, the protection circuit is "visible" as at the bottom of the cell.

Thanks for the info,

I did not pay attention on that since it is re wrapped.

Thanks for the review. :)

is there protected version of this ones?

And where to find them?
