Tiny Whoop Charger

thingiverse

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 four of the five TP4056 Battery Charger Modules. Step 3: Un-solder the "current resistor" on all five TP4056 modules, as shown in photo 7, and replace them with the 10k resistors. This will limit the charging current to 130Ma. Step 4: Use hot glue to attach the TP4056 Module WITH the micro USB connector in the center of the 3D printed case so that the micro USB is accessible through the slot in the case. Step 5: Using more hot glue, attach the remaining four TP4056 modules in the case next to one another so that the power + and - are all at the USB end of the case. Step 6: Now that they are all glued into the case, you will need to wire all of the positive power connectors (labeled "Power +" in photo 7) together and do the same for all the negative power connectors (labeled "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 that they are flush with the flat side, which will stop unwanted shorting. Step 9: Starting from the left side, solder "Bat-" to the negative side of the 2.0 JST PH connector and then complete by soldering "Bat+" to the positive 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 to cover all solder joints. Step 12: Using superglue, close the case.
