• Product description

  • The upgraded Fenix 21700 5000 mAh rechargeable batteries V2.0 (ARB-L21-5000 V2.0), featuring protection circuitry (protected), are built on advanced LiNiCoO2 technology, delivering enhanced safety and extended service life.
  • Li-ion rechargeable batteries offer very high capacity, are free from memory effect and exhibit minimal self-discharge.
  • 21700-size Li-ion cells deliver the best energy density relative to size and weight, increasingly adopted in sectors such as the automotive industry.
  • Fenix batteries' protection comprises internal safety mechanisms and protective electronics.
  • The added electronic circuits prevent overcharging, excessive discharge, short circuits and overcurrent.
  • If the battery electronics detect that limit thresholds have been reached, they safely disconnect the cell.
  • The internal protection consists of a separator, state-of-the-art overheat protection (PTC - Positive Temperature Coefficient) and a dedicated pressure-relief safety vent.
  • If the gas pressure inside the cell exceeds a certain threshold, the internal separator isolates the electrodes, effectively stopping the exothermic reaction, and the safety vent releases the excess gas pressure outside the cell.
  • Thanks to the combination of electronic and mechanical (thermal and pressure) protections, Fenix batteries rank among the safest available Li-ion cells.
  • Nominal voltage: 3.6 V.
  • Maximum continuous discharge current: 7.5 A.
  • Maximum charging current: 5 A.
  • Protection against overcharge, deep discharge and short circuit (>14 A).
  • Protection circuit attached to the positive terminal.
