Bench Test Results: EBAT 30A 3000mAh 20700...a genuine 30A battery, same as iJoy/Efest/Ampking

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. You are responsible for your safety.

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 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
While this cell lists the true 30A continuous current rating on the wrap it also has a useless “Max Pulse Discharge” rating of 40A on the other side of the wrap. Without knowing the length of the pulses, the time between them, and the criteria used to set the rating (voltage sag? vaping time? temperature?) the rating is useless.

This is a shame as it appears to be the same cell as the iJoy, Ampking, and Efest 20700's. The EBAT uses a plastic top ring insulator though versus the paper insulator on the iJoy and Ampking. This might make a difference to those who often get e-liquid on the battery.

Three of the six EBAT’s I tested didn't perform quite as well as the others though. This same performance variation seems to exist for the cells from all the companies wrapping this 20700. I don’t think these variations would be noticeable while vaping though as they are small at 3.2V and higher.

I am very happy to report that this cell doesn’t say "IMR" anywhere on the wrap. Since these 20700’s do not use the battery chemistry often associated with the “IMR” model number prefix there is no reason to have “IMR” on the wrap like the Efest cell does.

I am rating this EBAT at 30A and 3000mAh.

Six cells were donated by EBAT for the purpose of testing (www.ebatpower.com). Thank you!

Comparison of the performance of the six EBAT 20700's



Comments

• At 10A continuous this cell delivered 2837mAh. This is good performance for a 3000mAh rated cell at 10A so I am rating it at 3000mAh.
• EBAT paid a fee to be moved to the front of the testing queue, which currently has an 8-10 week backlog. This cannot influence my test results as they pay in advance and I don’t care if any company never donates batteries again. My reputation is a lot more important than any battery donation or payment.

30T, VTC5A, VTC6.

 

Samsung 30T

 

Yes, Boxer mech squonker.

 

They're not in stock anywhere. Hopefully they're available again later this year.

 

No, the Captain does not fit 21700 batteries. It is a 20700 device. Do not try to drill it out to fit 21700's. Especially since the 30T is not available anywhere.

About the best you can do now is the 30A Ampking/EBAT/Efest/iJoy 20700. They're all the same battery.
