Sir mrel . . . . .
Initially . . . . .
re . . . . . Ask the seller what the Out + and Out - pads do
They are being the respective polarity connections that go to the Li Ion cell being charged.
The identical ( jumpered together ) OUT + and B+ connections, uses the OUT + connection to go to the Li Ion cell, while the B+ marked connection goes to your powered circuit / equipments + supply line.
Then the OUT- pad goes to the Li Ions other terminal.
Then that just leaves the B- terminal to connect to the - of the circuit / equipment being powered.
BUT that B- connection is made thru a pair of switched FETS so that power connection of battery / cell to equipment can be opened if the cell is drained down to a damaging levels threshold.

See if this supplied info will fulfill your required project needs:
Top pic is the meager " plastic baggy" *** LI Ion cell used in the BT-100
Mid pic are the multiple intra connections relevant to the BT-100
***
These are the types, and its larger cased variants that pooch out and leak if over abused on charging or heavy discharges.
The leakage you can detect, by it being a sweet antifreeze type of smell, if sniffing out a cell..
Inversely . . . . the venerable 1860 metal cased build is the real workhorse and safer unit.
The Bottom pic is letting you see the 3 principal components utilized in the charger board.
There is the Top Power . . . .
Tire Pressure 4056
The

And the final Dual N chan mosfet switch . . . .
FS8205A
FUNCTIONS . . . . .
The TP4056 is being a smart Li Ion cell charger in a chip
The DW01 is being the voltage sensing and battery protection I.C.
The 8205A is being a single cased pair of FETS used as a power switch to make a disconnect of the negative voltage supply buss, at a set cutoff threshold, when battery usage drains down to . . ~ < < < 3 VDC.
SOOOOOOOOO . . . . . if you run your new charger to the lithium Ion cell which is connected to the two pin plug of the BT-100 with the red and black wires,that should get power to charging the cell and the cell is then feeding into the unit to operate the system.
NOW one clarification . . . .on your unit . . . your internal charger electronics should still be good and functional since your PROBLEM was being able to get + 5VDC power into the unit by a boogered up mini USB connector.
Observe the new charger board and you will see the top left corner is the +5VDC power that you put into the unit.
Additionally the bottom left corner is that power inputs negative rail. That gets +5 VDC in from a USB connection .
The 4056 circuitry then does its internal magic and gives you the proper 3.8 ----- > 4.2 VDC to charge your single connected Li IIon cell.
That processed charger voltage is outputted at the top right corner B+ connector at a jumpered together option of two identical connections .
The dual connection intention, is for one + to connect to your cell and the OTHER + to go to the equipment being powered ( not your situation).
I have drawn in the easily interpreted RED wire at the top.
Now here is where the difference is being, and that is the bottom option between the two terminals there.
For those bottom two SEPARATE connections , the very bottom connection would go to the megative terminal of the Li Ion cell.
The OTHER terminal, above would go to the negative connection the equipment being powered.( not your situation).
I have drawn in the easily interpreted BLACK wire at the bottom.
Now, if EXTERNAL power input is being used on the unit, it should run continually.
However, if you are external power disconnected and using that charged battery for power, that class D audio amp and WI-FI modules consumption, should run about 2-3 hrs on a full charge.
What we are NOW dependent upon, is the units existing internal charger detecting the low battery charge level and disconnecting the BT-100 electronics from the battery.
Look back to the new charger and see that other optional wire / terminal would then normally go to the loading circuitry ( the BT-100's ) ground return .
BUT without a schematic, we can't find that connection point on the BT-100 to connect it so that the 8205's switched FETS then disconnect / drop the equipments - ground connection. That saves further cell discharge on down into the never-never level.
We're banking on the internal charger circuitry doing that disconnect function.

NEW PHOTO REFERENCING:
To 73's de Edd
The picture you post of a philip speaker is not same as the BT100w speaker , parts inside the BT100w speaker is complete different from your picture.
As for the pictures i post to forum i look at the picture on my computer look clear to me,i don't know what else can do to the pictures to make any clear.
As for the speaker BT100w got red (positive) wire soldered directly to battery pack positive side of the battery pack and black wire (negative) soldered directly to negative side of the battery pack.
I measuring the voltage on the TP 4056 charge board where say out + and out- the voltage output is same as input voltage(5.17 volts).
The the pad on the board that has the ( B+,B -) voltage reading 4.1 volts is this where should connect battery pack wire from the speaker to the tp4056 charge board?
