I have a heated vest through "The warming store" This vest requires 7 volt rechargeable Lithium batteries. I ordered 3 batteries on 11 - 27 - 2014. It was 1 year and 2 months and they all quit. So I contacted them but no response. So this is my question; how long do these batteries last? Since I had 4 batteries with 1 used up fully each day I didn't get my batteries each to last 500 hrs. which is what the local battery store told me. Am I expecting too much out of these batteries? Right now I just wish I could buy some new ones from another source but I can't find another source.

Good reading. Very informative.
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 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, 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!
