   Hello
   i’m a novice but a few things are not clear for me:
   1) the resistor shouldn’t be on positive pole of the 18652? it seems alternate from positive to negative pole of 18650s
   2) the 270ohm resistors between 18650s shouldn’t lower the current between batteries for a max of 15mA ( V=IR)? i have seen in the video on the multimeter current above 1A.

   Thanks

      This is just one of the influencing factors.

   Hi,

   Is the current limit resistor 0.27 Ω? I don’t think it’s 0.27KΩ.

   How many chargers do you use? What is the total current?

   Thanks
   Stephen

      Yes! 0.27Ω I use an adjustable power supply for charging.
