I am trying to charge my three LiPo cells with these TP4056 modules.

My Idea:

  • \$\begingroup\$ What is your question? By the way, it will not work since the the TP4056 does not have any isolation. \$\endgroup\$ – winny Dec 14 '16 at 11:59
  • \$\begingroup\$ my question is how can I charge my three LiPo cells with these modules and get my 11.1 volts in the end. \$\endgroup\$ – TheDude Dec 14 '16 at 12:07

    \$\begingroup\$ No. There is a short between IN- and B- for each cell in the TP4056 and you have shorted it on the input. You need to float them/have isolation somewhere. \$\endgroup\$ – winny Dec 14 '16 at 12:15
  • \$\begingroup\$ I am pretty new to electronics. Can you explain how I can accomplish it to "have isolation somewhere"? \$\endgroup\$ – TheDude Dec 14 '16 at 12:21
  • \$\begingroup\$ Can you get three separate 5 V supplies, one for each TP4056? \$\endgroup\$ – winny Dec 14 '16 at 12:26

Thanks for helping @winny

  • \$\begingroup\$ Given that the 5 V supplies are isolated from each other, that will work. You are welcome! \$\endgroup\$ – winny Dec 14 '16 at 16:02
  • \$\begingroup\$ This is still a very bad idea. \$\endgroup\$ – Chris Stratton Mar 8 at 15:19
