The Samsung 50E li-ion battery is one of the most powerful and reliable cells available in the 21700 size, and boasts a 5,000mAh capacity that's sure to keep your electronic devices running longer. As this battery is unprotected and features flat top terminals, it is recommended for use in battery packs.
INR Chemistry
The 50E 21700 battery's chemistry is lithium manganese nickel (LiNiMnCoO2). INR chemistry is ideal for powering a variety of high-drain devices, as seen with the 50E's 14.7A pulse (and 9.8A max continuous) discharge current.
This li-ion battery is 100% rechargeable, allowing you to save money and help the environment out, one charge at a time. You can check out our selection of 21700 chargers, but we recommend the XTAR SV2 Li-Ion Charger as a universal charger for INR batteries.

One thing you have to be careful with are the possibility of getting low quality and/or counter-fit lithium rechargeable cells. These are the real deal. They work great in my ZebraLight 700d

Great batteries overall. I use these for high powered LED Flashlights and they work great. Unprotected batteries work especially well with turbo (mode) power options on LED lights. Highly recommend these top quality batteries from Samsung.
