Those batteries are rated the same as standard lithium-ion batteries yet no one guaranty about their lifespan and also their performance is not as good as you expect.
This battery pack is made up of the best quality tested ICR 18650 2200mAh 22F Lithium-Ion Batteries and BMS circuits. It is small in size and weight compared to Ni-Cd, Ni-MH, and Lead Acid Batteries. With the inbuilt Charge protection circuit, the battery pack can be directly charged with the DC power Adapter, so need not use the specialized battery chargers and worry about overcharging.
Features
High energy density
Capacity, resistance, Voltage, platform time consistency is good.
Good consistency and low self-discharge.
Very Small in size and weight when compared with Ni-Cd, Ni-MH, and Lead Acid Batteries.
Full Charge in 40 to 90 minutes depending upon the special charger.
Long life with full capacity for up to 500 charge cycles.
Inbuilt (BMS) battery protection circuit.
Good consistency and low self-discharge.
The battery will work within a voltage range of 11.1V to 12.6V.
The BMS will cut off the battery at approx. 5 V to prevent over-discharging.
The maximum safe charging current is 2200 mA.
The recommended charging current is a maximum of 1100mA for longer life
High performance and capacity
Flat top to suit many devices fitting.
