AW IMR 1600mAh v Efest IMR 1500mAh v Sanyo UR18650W2


After seeing the AW IMR 2000mAh outperformed by the Efest IMR 2000mAh and Panasonic CGR18650CH, I wondered how the AW IMR 1600mAh would fare against the Efest IMR 1500mAh and Sanyo UR18650W2.

At !A discharge the Sanyo edges it with AW and Efest looking very similar.

At 5A discharge the AW and Efest are almost identical to Samsung INR18650-15Q.

I'm guessing you mean 1A discharge?

I think many would really appreciate 10A tests of these + the other cells. Smile

The AW and Efest are too similar to the Samsung INR18650-15Q for coincidence.
Maybe 15A would be a better test.

10A, 15A, 20A.. whatever you like. Smile

For these also, if possible:

Much appreciated, I'm looking to get some IMRs in the near future..

Since IMR are supposed to discharge a high current without thermal build up, I thought a measurement of the battery temperature at 10A continuous current would be a relevant test:


I know Panasonic test at 60 degrees C, but I wanted a safety margin (don’t know how much higher the internal temperature is compared to the external) and set the cut off temperature at 50 degrees. s

I’m not sure why LG rate their discharge currents so low on their LiMnCo batteries:

They don’t seem any better than standard LiCoO2
