The AA sized high current LiIon from Vapcell.

Nice looking discharge curves, the cell performes well with nearly constant capacity up to 3A, but 5A is to much.


A good performing cell with both fairly high current and capacity, but the chemistry type used has a slightly low voltage at high currents.

Notes and links

The batteries was supplied by Vapcell for review.

How is the test done and how to read the charts
How is a protected LiIon battery constructed

Comparison to other LiIon batteries

putting this on my list of cells to get. Thanks and good review as always
