• The R series from Keeppower differs from the standard rechargeable batteries in that it has a higher current-carrying capacity. Current-hungry applications such as high-end torches or searchlights reach maximum performance with the R series batteries;
• The base cell of the 4250 mAh battery is a quality industrial cell from Panasonic/Sanyo NCR20700B.
• Keeppower 21700 / 20700 Lithium-ion battery PCB protected up to 15A
  
• Equipped with Seiko (Made in Japan). Protection/PCB with short circuit, overcharge and deep discharge protection as well as overcurrent up to 15A, the Keeppower battery is suitable for virtually all torches.
• Recommended use: torches, diving lamps, video lamps, model making, industry and all applications where the 74.5 mm length and 20.7 mm thick cell fits and is suitable according to the specifications.

Please note the dimensions of the cell before buying! Due to the built-in electronics, the cell is not suitable for every application! Height and diameter are larger than a standard 20700 cell without PCB.
