The battery does very good up to 2A, at 3A the cells show variations.

[size=+3]Conclusion[/size]

The battery has good performance and at can match some IMR cells at 2A (It has more capacity and about same voltage).
I will only rate the battery as acceptable, because it uses an unknown cell.



[size=+3]Notes and links[/size]

The battery was supplied by Xtar for review.

Very interesting! Easily the highest capacity 18350s I've seen tested. :thumbsup: However, I'd be especially impressed if they can maintain this level of performance after very many 3a discharge cycles. I intend to find out.

Where to buy?

It would be great if Xtar could tell us when and where these cells could be bought. Never know, might sell a few that way!
