This is a shorter post and not a review of the cells themselves so much as it is a commentary on getting them from GearBest.
We all know that there are issues shipping Li-ion cells into the USA. GearBest has a huge selection of 18650s, but the shipping issue has prevented us from ordering cells there lately.
Well GearBest has a bunch of cells in a US warehouse now, and I got my hands on some of the Panasonic NCR18650B.
The NCR18650B should be a 3400 mAh cell. I tested each of these 4 cells using my Opus BTC-100 analyzing charger, and found the following:
|Cell||Tested Capacity (mAh)||Internal Resistance (mR)|
These numbers meet my requirements for a cell being “at capacity” (even though they’re ~150 mAh “short”). This is normal to my knowledge.
The internal resistance is also within the norm for my cells. (It’s also reported that the Opus reports mR a little high.)
So these cells seem to me to be genuine Panasonic NCR18650B’s.
They are in stock and shipping from the GearBest US warehouse.
