    A good idea, but I would advise putting a BMS on this battery or using the one built into those tp4056 boards because that way, without protection, it can overload and, in the worst case scenario, burst into flames

    Really? Charging a Li-Ion cell without using a Li-Ion Charger-IC? I can see your house burning down.
    You need a Over and Undervoltage, also a overcharge protection for this Li-Ion. Also Li-Ion cells gets charged with "CC-CV" Constant Current, Constant Voltage. You need a constant voltage of 4.2V and about 1A, less or more dosnt care. As long the current is about 1/2 capacity in mA.
    Better buy a $1 IC called "TP4056". Its made for charging Li-Ion and Li-Po cells. It provides a CC CV, also a under and overvoltage protection, also an overcharge protection.
    People here: DONT copy that build or your house will burn down. Use a TP4056 and this circuit wont be a problem anymore.

      hallo Andreas,
      ganz so schlimm wird es schon nicht werden, dass er seine Hütte in Schutt und Asche legt ;-) er hat ja eine Diode in die 5V Leitung zum Akku geschaltet, also kommen dort ohnehin nur rund 4,3 V an. das eine Zehntelvolt, um das die maximale Ladespannung jetzt noch überschritten ist, verbummelt sich in seinen Leitungen und Anschlüssen :-)
      zusätzlich kann das Solarmodul unter günstigten Voraussetzungen maximal 100 mA liefern. wenn ich von meinen Vorausetzungen ausgehe (= 8 Sonnenstunden/Tag) dann braucht der Akku mehr als 5 Tage, um auf seine volle Kapazität aufgeladen zu werden. nachdem der Akku im Video auch schon einige Zeit am Buckel zu haben schient, hat er in der sonnenlosen Zeit bestimmt eine hohe Selbstentladung, sodass er ohnehin nie seine volle Kapazität erreichen wird.
      meine erste Idee beim Zuschauen war auch: warum nimmt er kein Modul mit einem TP4056 und vielleicht auch noch mit einem DW01A drauf, dann hätte er gleich 2 Fliegen mit einer Klappe erschlagen. sonst muss er den Tiefentladeschutz anders bewerkstellingen, denn der MT3608 in seinem Aufwärtswandler arbeitet bis ungefähr 2 V hinab. somit ist die Entladespannung des Li-Ion auch schon lange unterschritten. also lange halten wird er nicht.
      und ich gebe dir recht, ein solches Ladegerät zu bauen ist leichtsinnig, da Li-Ion auf Überladung brandgefährlich reagieren. bei dem Mini-Solarmodul sehe ich nicht die große Gefahr, aber der nächste schließt an Stelle des Moduls ein leistungsfähiges Netzteil an, tauscht den 7805, der auch schon bei 1A abregelt, gegen einen Regler aus, der mehr Power liefert und dann kann der Akku tatsächlich anfangen zu brennen.
      gruß,
      Stefan
      ps: gute Fahrt und achte auf die Bodenwellen ;-)

    The performance of this panel is at such a low level that it is almost impossible to charge this battery. I think it's about 30-50mAh. It takes 5-6 pieces to make sense, even with that number, it would take many, many hours.
    I don't say anything about the connection itself, everyone can see that no charging module has been used.
    Do it right and show it, plus for creativity. ;)
