One of the more uncommen LiIon sizes from AW.

These discharge curves tracks perfectly and the capacity is constant at any load.

At 3A the cells will warm up, but not that much.


This look like a good cell and this size can be useful. The capacity and current handling is not that great, but when used as replacement for CR123 the performance is more then enough.

Notes and links

Two of these batteries matches 3xCR123 fairly well in both voltage and size and the protection will prevent the batteries being damaged when the run empty.

The batteries was supplied by for review.
