Keeppower 3600 mAh 18650

Great news, I hope these new cells (if new tech at all) have decent discharge curves.

2600 >>> 2900 = 300mA
2900 >>> 3100 = 200mA
3100 >>> 3400 = 300mA
3400 >>> 3600 = 200mA
3600 >>> 3900 = 300mA :wink:

Just heard back from KP. Specs/Pricing/Release Date are all to be determined.

HKJ, thank you for maintaining such an excellent database of cell discharge comparisons. Without your hard work in producing empirical data, we’d all be stuck not knowing which cell is truly better than the next. Your Battery test 18650 comparator has been an invaluable tool for most of us.

lt will be interesting to see a 3A discharge curve for the new “3600” cells, and of what percentage of total capacity is maintained above 3.5V while under load. I suspect they will sag at least as bad as the pana NCR18650B’s, especially in single cell performance applications. Now, if we only had 17-21mm 4.2V 3A boost drivers available to take advantage of the low voltage incurred after the first 33% of cell depletion…

Thanks for checking.

Where can we source the Kp’s stateside…?

The voltage curve gets’ pretty steep at that point though. The extra .3v is only worth a few more mAh, there’s certainly not ~300mAh in those last tenths of a volt.

E2 Field Gear has a few nice cells here. http://www.e2fieldgear.com/keeppower-li-ion-batteries/
