This is a 26650 LiIon battery with fairly good capacity and current capability.











The two cells match nicely and do easily have the rated capacity. As usual I try a bit above rated current, on this battery it was not a good idea. It has some sort of fuse (Probably temperature based) that blows when continuous overloaded, it is good good safety, but I could not finish my test on the first battery. For the second I reduced maximum test current.























Conclusion

It is a good battery that can deliver a lot of current and capacity and it has protection against getting too hot.
