Prying off the bottom cover uncovers a series of Phillips screws hidden beneath it.

Next, we pry open the internal assembly from the orange top cover on the other end.

After unscrewing the base, the PCBA and battery pack can be pulled out from the top. The PCBA is linked to the battery by red/black power wires and two thermistors.

The battery pack, wrapped in black shock-absorbing foam, is housed in a white plastic protective frame.

The white plastic frame housing the battery pack is lined on the inside with black insulating and shock-absorbing material.

The battery pack features three series-connected lithium-polymer pouch cells, with the electrode tabs undergoing thorough insulation treatment.

The three unfolded battery cells are identical in specs, providing the necessary foundation for high-power output.

The battery cells are from GFL, spec 606273, 3.91V and 5,000mAh, and energy rating of 19.55Wh; the three cells provide a combined capacity of 15,000mAh.

Two NTC thermistors are integrated within the battery pack for OTP.

The rear of the top PCBA module is insulated with a full sheet of green fishpaper.

Removing the fish paper exposes the components on the PCBA module.
