So, now, some capacity tests! I’m using my own battery holder with my own large Beryllium Copper spring, which allows accurate capacity testing up to 3A without a 4 wire method. -I first started testing the NCR18650GA at 2A current, with a charge voltage of 4,185V and ending voltage of 2,6V. Capacity at 2,6V, being 3308mAh. [image] Energy at 2,6V, being 11,56Wh. [image] Capacity at 2,8V to compare with HKJ. [image] Nothing checks out, so I can confidently say NCR18650GAs from the Aliya …

INTERNAL RESISTANCE TESTING FOR THE SAMSUNG 30Q Here is a chart with some DC internal resistance values. The 30Q has 21mOhms of internal resistance according to this graph. [image] And with my measurement, a minimum measured DC internal resistance of 21mOhm! [image] Right on spec! Actually, better than most 30Qs. I can therefore say again, that the 30Q from the Aliya Battery Store is a legit cell. So, for Canadians all around the country, you can be assured to get …
