While the test results are hard data, the conclusions and recommendations I make based on these tests are only my personal opinion based on my criteria for setting a rating. Carefully research any cell you are considering using before purchasing.
Testing cells at their limits is dangerous and should never, ever, be attempted by anyone who has not thoroughly studied the dangers involved and how to minimize them.
If the cell has only one current rating number on it, or if it only says "max" then I have to assume that the company is stating that the cell can be discharged at that current level in any way, including continuously.

Bottom Line
This cell is a 20650. It is 20mm in diameter and 65mm long. It does not have the usual LG four “leg” top contact. This cell only has three “legs”.
I can’t find the datasheet for the HG6 but postings I’ve seen so far show it as a 30A cell with a minimum capacity rating of 2900mAh and nominal capacity rating of 3000mAh.
In my testing it easily outperforms the excellent Sony VTC5A and runs cooler than the LG HB6. It is a great performing true 30A cell.
Against the other 20mm diameter cells it also does well. Down to 3.2V the HG6 equals or beats by a little the Sanyo NCR20650A or iJoy 5-leg 20700. The Sanyo NCR20700A still beats all of them, but not by a lot.
While rated at 3000mAh, cells I tested from two sources and having two different batch/date codes only delivered about 2800mAh of capacity at 0.5A down to 2.5V. This is 100mAh lower than its minimum capacity rating. LG uses a cutoff voltage of 2.0V though for their capacity rating for this cell. If I ran them down to that level I think they would meet the 2900mAh minimum rating.
To allow for direct comparisons of any cells I test I set my capacity testing cutoff voltage at 2.5V. Since two HG6’s, from two different batches, tested near 2800mAh when discharged at 0.5A down to 2.5V I am rating this cell at 30A and 2800mAh. It still tests out well, as described above.
Two cells were donated by EcoLux (Ecolux UK's rechargeable battery and accessory specialists EcoluxShopDirect.co.uk) for the purposes of testing. Thank you! Two other cells were purchased by me.
