TP4056 modules with 18650 lithium cells


These tp4056 can charge at lithium battery up to 1A. https://dlnmh9ip6v2uc.cloudfront.net/datasheets/Prototyping/TP4056.pdf


I would like to use them in series but charging each battery separetely because the TP4056 modules cannot be wired in serial due to common ground.


But i've made a schematic and i would like to know if it will work or explode.


Here : enter image description here


In this circuit each module have a tp4056 chip, a dw01 single cell protection ic and a dual mosfet.


The switch is used for the charge or for out 11.1V so you won't be able to use the +11.1V while charging it and it's a dpst switch so no common ground problem.


Can I wire these modules in series?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
