The Keeppower 32700 5000mAh is a high-capacity, high-discharge rechargeable lithium-ion battery designed for compatible high-power flashlights and other demanding electronic applications.

With a nominal capacity of 5000mAh, an energy rating of 18.5Wh, and a maximum continuous discharge current of 30A, this 32700 battery provides a combination of extended energy capacity and high-current performance.

Important: This is an unprotected Li-ion battery without a built-in PCB or protection circuit. It must only be used in compatible devices with appropriate battery protection and voltage management.

5000mAh High Capacity

The Keeppower 32700 battery provides a nominal capacity of 5000mAh, with a manufacturer-specified minimum capacity of 4800mAh.

Its 18.5Wh energy rating makes it suitable for devices requiring substantial battery capacity in a cylindrical rechargeable cell.

Compared with smaller battery formats, the 32700 offers a larger physical size and substantial energy storage for compatible equipment.

Up to 30A Continuous Discharge

Designed for high-drain applications, this battery supports a maximum continuous discharge current of 30A, according to the specified cell version.

This makes it suitable for compatible high-output flashlights and other electronic equipment that require substantial current delivery.

Actual discharge performance depends on operating temperature, device design, and battery condition.

Unprotected Battery – No Built-In PCB

This battery does not include a protection circuit board (PCB/BMS).

Unlike protected Li-ion batteries, this cell does not independently provide electronic protection against overcharging, over-discharging, overcurrent, or short circuits.

It is intended for compatible devices with appropriate protection electronics or professionally designed battery management systems.

Do not use this battery in devices that require protected cells unless the device manufacturer explicitly approves its use.

Rechargeable 3.7V Lithium-Ion Battery

The Keeppower 32700 features a nominal voltage of 3.7V and a maximum charging voltage of 4.2V.

It requires a compatible Li-ion charger using an appropriate constant-current/constant-voltage (CC/CV) charging profile.

Always verify charger compatibility with the battery's physical dimensions and electrical specifications before charging.

32700 Battery Format

With approximate dimensions of 32.5mm × 73mm, this battery is significantly larger than common 18650 and 21700 cells.

The 32700 format is designed for equipment specifically engineered to accommodate its diameter, length, terminal configuration, and electrical characteristics.

It is not a direct replacement for 18650, 21700, or 26650 batteries.
