High capacity and high current in a 26650 cell.

There is a piece of paper on the connection to prevent any risk of shorts.

There is a small difference between the two cells, but it is not huge. The cells handle up to 15A without any change in capacity, above that current the capacity goes down.

AT 20A the cells gets hot, but it is just about acceptable.

At 30A I terminated one of the tests due to temperature, but that was only a few seconds before the test would have stopped anyway.

Saw the photo before the title, and for a second I thought A123Systems are back in the game.
Well, I guess not. Sad

Thank you for testing these cells. Will be buying more 26650’s soon so these will be added to my list to price check before I decide what to purchase.

Thanks for the review!

When I first saw it I thought, he already did that battery!,,,ohh,,the 5000mAh version.

I have the VP 4200mah battery in one of my modded lights. It works very well, For me, the capacity is not that important because I change the batteries in my single cell lights after 15 to 20 minutes maximum! I love max output!

Good to know that it performs well.

Solitude breeds contemplation which creates clarity. 

Environment molds a person. Perseverance changes them.
