This is a Tiny whoop lipo charger. This charger charges at 130Ma and uses the TP4056 Battery Charger Module.

NOTE: THIS IS FOR SOMEONE WITH ADVANCED SOLDERING SKILLS!!

Requires,
A soldering iron
A hot glue gun
Superglue
5 TP4056 Battery Charger Modules
5 10k Resistors
5 2mm JST PH connectors
And of course the 3D printed case

Step 1: 3D print the case.

Step 2: Un-solder the micro USB connectors from 4 of the 5 TP4056 Battery Charger Modules.

Step 3: Un-solder the "current resistor" on all 5 TP4056 modules as shown in photo 7 and replace with them with the 10k resistors. This will limit the charging current to 130Ma.

Step 4: Use hot glue to glue the TP4056 Module WITH the micro usb connector on in the centre of the 3D printed case so them micro usb is accesable threw the slot in the case.

Step 5: using more hot glue glue the remaining 4 TP4056 modules in the case next to one another so the power + and - are all at the USB end of the case.

Step 6: Now they are all glued in the case you will need to wire all of the posative power connectors (Labled "Power +" in photo 7) together and do the same for all the negative power connectos (Labled "Power -" in photo 7).

Step 7: Moving on to the top of the case, Using superglue glue the 2.0 JST PH connectors into each of the square holes making sure that they are inserted in the same orientation as photo 6 and are flush with the flat side.

Step 8: bend down the pins on the 2.0 JST PH connectors so they are flush with the flat side, This will stop unwanted shorting.

Step 9: starting from the left side solder "Bat-" to the negative side of the 2.0 JST PH connector. after completed solder "Bat+" to the posative side of the 2.0 JST PH connector.

Step 10: repeat step 9 for the rest of the 2.0 JST PH connectors.

step 11: use hot glue cover to cover all solder joints.

step 12: use superglue to glue close the case :)
