I was given a few 18 volt dewalt tools by a friend. I already owned a few 14.4 volt dewalts. Today at the end of the day, my buddy and I did a little closer inspection and came to the conclusion that we could make a 14.4 fit into an 18 and vice versa , and the tools worked.
Any body out there know the effects of doing this or if there even is a problem. Life would be alot easier if the batteries were all interchangeable.
Have a good day

If you run higher voltage through a smaller motor, the life of the motor will be shortend.
I see that happen in the RC world (they are the same motors).
According to RobotMarket Place the 14.4 Dewalt motor can be over volted.

you saying the 14.4 and 18V DW motors are the same and the 14.4 is being over volted by 3.6 volts???

No, I looked it up.
The 18v motor is closer to the 24v motor than the 14.4 motor.
When I said there the same motors I meant a lot of RC motors are what you see in cordless tools.
The old standard 9.6v Makita known as a 660 motor is quite common in RC tugboats ( very tourqey ) if that's a word ;-)

are the fields and armatures different or so close to one another it's a tuff call....

At Least with Bosch cordless stuff, they are designed to be usable with the lower voltage batts. So you run the 18 volt drill or jigsaw with a 14 or 12 or 9.6 batt.The tools are designed to accept the lower voltage batts. There are special molded in "keys" that won't let you go the opposite way. You cannot run a 12 volt drill with a 18 v batt.I find it very handy cause I can run my 24v miter saw with my 18 batts in a pinch, and I have some Skil 12 volt batts that I can use in my 18 volt drill in a pinch as well.I think I remember Dewalt cordless being the same way. In fact, some tools, like the little cannister vac or the radio are designed and labeled to accept any of the batteries. But others, like the cool little wet/dry vac is only designed to be run by 18 volt batteries.JT
