Add Tekin to that list. We will be submitting a hard cased 3400mah battery for approval very soon. After 18 months of testing different manufaturers cells we have found one worth putting our name on.
We will even tell you where they come from, what they are and show you all the safety certifications. We will be the only ones selling these cells made exclusively for Tekin by one of the top manufacturers in the world.
