Bottom Line: This rewrapped cell has exaggerated current and capacity ratings and is the same as the older yellow wrap “20A 3500mAh” MXJO. When discharged continuously at its claimed 20A rating an internal protection device is triggered at around 100°C, permanently disabling the cell. This helps protect it from venting but renders the cell useless and means it cannot be rated a 20A cell.
This new green/silver wrap has “Type 1” above “10A CDC” in small print on the “back” of the cell. I assume that means Continuous Discharge Current. While I applaud MXJO for putting this rating on the wrap, it’s almost hidden and is essentially useless as very few people know what “CDC” means. In bold print on the front they have a meaningless 20A max or pulse rating with no mention of the continuous rating, which would be easy to add there. Even if they kept the continuous rating on the back of the cell they could have said “10A Continuous” or even “10A Cont.” and used much larger lettering.
These MXJO’s are identical in appearance and performance to the 10A/3300mAh Panasonic NCR18650GA. The 18650 ratings table has been updated to include this cell.
