26650 LiFePO4 Battery 3000mAh 3.2V

Stepping up the capacity from their 18650 cousins, these 26650 Lithium iron phosphate (LiFePO4) batteries, are a more chemically stable type of lithium rechargeable cell. They have a slightly lower capacity and nominal voltage than equivalent Li-Ion cell, but can be charged/discharged around 2000 times versus 500-1000 times for Li-ion, and deliver higher peak currents.

NOTE: This is an unprotected rechargeable lithium battery (Li-Ion or LiFePO4) which is only suitable for use in a compatible device/charger. Use of a unprotected cell where a protected cell is expected is very dangerous, please review your product's user manual before proceeding.
