The battery is most likely a 3S Li-ion pack, i.e. 3 cells/packs in series. Protection circuits for single cell Li-ion normally have overdischarge protection set somewhere in the range 2.5V-3.2V per cell, which translates to 7.5V-9.6V for a 3S pack.
Next I tried was to desolder pack+ from the battery protection board, and connect it to my bench power supply set to 7.5v, I left pack- connected to the protection board and also connected that to the bench supply. This makes the power led on the device flash as before, even without the charger plugged, but that''s it.

The Lithium battery protection board is a small size board that provides protection against short-circuit, overcharge and overdischarge. The board comes with pre-soldered Nickel strips which makes it a ready-to-use module with 18650 cells.
Battery protection unit The battery protection circuit disconnects the battery from the load when a critical condition is observed, such as short circuit, undercharge, overcharge or overheating. Additionally, the battery protection circuit manages current rushing into and out of the battery, such as during pre-charge or hotswap turn on. BMS IC ...
Perhaps the best solution could be combining the use of the protection board and incorporating a set of balance charge wires in the battery pack itself. This approach would protect the cells on discharge via the protection circuit (cheap 3s "BMS") while also relying on the external balance charger (e.g. IMAX B6 or B3) to properly balance charge ...

Does the Extension Pack come with batteries? Yes. The Extension Pack comes with four, 1.5V AA lithium-metal batteries.
A Battery Management Unit (BMU) is a critical component of a BMS circuit responsible for monitoring and managing individual cell voltages and states of charge within a Li-ion battery pack. The BMU collects real-time data on each cell''s voltage and state of charge, providing essential information for overall battery health and performance.
I am currently in the process of making a 3S 18650 battery pack using a BMS board that I purchased from Amazon. The image of the board can be found below: Yesterday, I successfully connected all the wires and charged the battery pack using an adjustable DC power source set at 12.6V. It worked well, and the battery pack was fully …
Lithium batteries cannot be without a suitable BMS. To choose the right lithium battery protection board, there are three points to remember.
The voltage of the battery pack = battery voltage of a single string * number of strings of batteries, according to the number of strings to choose the right voltage protection plate. Confirm the current value The current value is also quite an important part. Lithium battery application scenarios are rich, different application scenarios for ...
