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:
(1)
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?
(2)
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!
