My supplier is calling these cells Sanyo NCR18650BD however all my research has netted zero evidence of a cell by that name existing. I'm open to suggestions if anyone has further insight on the model.
I believe they are actually Sanyo NCR18650BF cells based on my test results.
At 1A discharge ~90% are testing at 2.8-2.9ah
At 5A discharge ~90% are testing at 2.4 - 2.5ah
The other 10% varies pretty wildly.
The cells are standard 18650 size with a button top.
We are guaranteeing these cells at 80/80
(AKA at least 80% of the cells will have at least 80% of 3.2Ah capacity at 1A discharge rate)
Due to the close proximity of the positive (button) terminal and the rest of the battery acting as a negative terminal we strongly recommend that the cells be wrapped and an insulator ring be added before they are put in a charger.
If used incorrectly they will short.
Last image shows the Positive (red) and Negative (blue) sections of the battery.
The specs for the Sanyo BF cells are below (No guarantee that is what these are)
