Callies Kustoms 2250mAh (Grey)

This battery is a high current battery without any protection!

Official specifications:

18650 Unprotected Battery
18650 2250mAh
10A Max Discharge
Max Charge/Max discharge voltage 4.2/3v
Panasonic uses "PSS Technology" in this battery. A solid solution technology that allows the high capacity of a standard Lithium-Ion battery and the safety of an IMR battery. This is truly a revolutionary battery!

Because this battery is without a protection PCB the size if very close to the official 18 mm diameter and 65 mm long.

I received the battery with a lot of bubble wrap protection and the batteries is in a soft plastic bag. Callies does also include a page about how to thread LiIon batteries.

With this battery I included tests up to 10A, where it still has lot of useable capacity.

This battery does not have any current protection and the curve only shows voltage under load. Doing 5 tests (Each takes about 100 seconds when running up to 15 ampere) did use most of the capacity in the cell. This can be seen on the last part of the last test trace.

I did have some problem with charging (Due to the very low resistance of the cell) and had to use a less than perfect CC/CV charging (This would never be a problem with a regular LiIon charger). The impact in capacity and charge time is negligible.

Conclusion

The battery uses a good cell, making it a fairly safe cell, but remember it is unprotected and must not be over discharged. For uses with high current this is a very good battery and it can deliver more capacity at a higher voltage than 3100 mAh cells when high current.
