AWT has two 3000mAh rated IMR cells, one with a 35A current rating and this with a 40A current rating.

The discharge curves looks very nice and the cell do well up to 20A, at 30A it has lost some capacity and voltage.


The 40A rating sounds a bit high, but the cell do handle 20A very well.

Compare the LG HG2 to the AWT 3Ah 40A.Same flat top.I am taking the AWT 35A as reference for the 30Q and this 40A for the HG2.
Thanks a lot for testing these Henrik.
Apart from initial voltage sag up to 0.3Ah , these hold their voltage better than the HE2,25R and VTC5.
