Bottom Line: This is an ridiculously overrated 15A battery. It’s great that it doesn’t have the useless “pulse” rating in large numbers on the wrap but its claimed 30A continuous rating is a huge disappointment. The Imren Gold 20A 2500mAh cell was accurately rated. I don’t know why they decided to exaggerate the current rating so much with this cell.
Perhaps it’s due to a misreading of the datasheet for the cell they rewrapped? This Imren looks and performs identically to the Sony VTC6 (but this can change at any time). As clearly shown in the VTC6 datasheet, it is rated at 30A only if you stop when the temperature reaches 80°C. Since this battery gets hot enough to boil water when discharged continuously at 30A this cannot be a 30A-rated battery.
The 18650 ratings table has been updated to include this cell.
