I picked these up at the Hall of Vape. They are not for mechs and high-amperage gear, but for how I vape at 28 watts, they should be winners.

Product information "L50 21700 Battery"
  • 21700-Battery
  • CDR 15A / Max 25A
  • 5000mAh nominal

Reached the maximum​

The L50 battery is the endurance champion among the 21700 style batteries and is designed for projects that require lower performance. With a whopping 5000mAh capacity, it is not so easy to get down with a maximum output of 55.5-45 watts and, with its constant output power of 15A, it ensures that your project doesn't run out of juice so quickly up to a battery level of less than 30%!

Battery safety​

At Golisi, special emphasis is placed on longevity and safety. The L50 is characterized by its exceptionally robust construction, which is already visible from the outside. An additional thick cover protects it if it accidentally falls. This design also delays the insertion and removal of the battery from chargers, which can normally lead to rapid wear of the heat shrink tubing at the ends.

Aside from that...​

The L50 battery is designed for long-term use and keeps its promise of reliable and safe energy delivery, even with a life cycle of over 800 charging cycles. Packaging that consists of 99.9% recyclable materials and contains no air also makes the “surroundings” a useful addition. In addition, with each L50 battery you will receive a battery transport box for two 20700/21700 batteries. Please never transport your batteries loosely and always use a transport box.
