Samsung 35E | Lithium Ion Cell 3500mah Cell



The 35E is a superior cell for the low-medium amp, extremely high capacity battery packs, and applications. 

The low continuous rating on this battery makes it NOT APPROPRIATE FOR USE IN HIGH DRAIN APPLICATIONS (e-cigs, vaporizers, or similar), but this is an exceptional 3500mAh cell that offers a solid 8A max continuous with 3500mah, and up to 13A manufacturer pulse rating.
