2. Lithium iron phosphate battery - Wikipedia

   en.wikipedia.org/wiki/Lithium_iron_phosphate_battery

   Lithium iron phosphate modules, each 700 Ah, 3.25 V. Two modules are wired in parallel to create a single 3.25 V 1400 Ah battery pack with a capacity of 4.55 kWh. Cell voltage Minimum discharge voltage = 2.0-2.8 V [27] [28] [29] Working voltage = 3.0 ~ 3.3 V; Maximum charge voltage = 3.60-3.65 V [30] [28] Volumetric energy density = 220 Wh/L ...

   Also used in larger, high-powered LED flashlights and some electronic cigarettes. This size is sometimes used in devices that can take either one 26650 or three AAA cells in series in a cylindrical 3-cell battery carrier. 26700: 4,000-5,000 26: 70 LiFePO4 cells. 26800: 5,500–6,800 [229] 26 80 A larger format for e-bikes and transport.

4. Rechargeable battery - Wikipedia

   en.wikipedia.org/wiki/Rechargeable_battery

   A rechargeable battery, storage battery, or secondary cell (formally a type of energy accumulator), is a type of electrical battery which can be charged, discharged into a load, and recharged many times, as opposed to a disposable or primary battery, which is supplied fully charged and discarded after use.

5. Battery charger - Wikipedia

   en.wikipedia.org/wiki/Battery_charger

   A battery charger, recharger, or simply charger, [1] [2] is a device that stores energy in an electric battery by running current through it. The charging protocol—how much voltage and current, for how long and what to do when charging is complete—depends on the size and type of the battery being charged.

6. Lithium-ion battery - Wikipedia

   en.wikipedia.org/wiki/Lithium-ion_battery

   A lithium-ion or Li-ion battery is a type of rechargeable battery that uses the reversible intercalation of Li + ions into electronically conducting solids to store energy. In comparison with other commercial rechargeable batteries, Li-ion batteries are characterized by higher specific energy, higher energy density, higher energy efficiency, a longer cycle life, and a longer calendar life.

7. Battery pack - Wikipedia

   en.wikipedia.org/wiki/Battery_pack

   A power bank is a portable device consisting of a battery, a charger to interface battery with charging power source and an output interface to provide desired output voltage. [10] Power banks are made in various sizes and typically based on lithium-ion batteries. A power bank contains battery cells and a voltage converter circuitry.
