hi battery experts,
I am battery ignorant but did build diy series dc motor to my
grandson. I cannot start it with my 50 v li-ion battery because winding
wire is so thick that calculated short time inrush current exceeds max discharge current 40 amps
of battery. 2 solutions in my mind:
I did figure out to use 3 pieces 12v amg batteries in series ( mtx 6ah, CA 107 amps).
What happens if I connect this to motor and inrush current for some tens of
millisecond is 130 amps and drops very fast?
Does batteries explore or give this 107 amps?
An other idea:
I make 3 input pins to motor, first i connect one battery and inrush current is some 60 amps,
then when back emf developed I connect 2 in series finally 3.
Does this seem a possible solution?
Many thanks to enlight me!
