Hello everyone. So I'm posting because I've run into a problem that I'm sure most other Modders will eventually run into at one point or another. So I figured I'd kill two birds with one stone and make a helpful post for both me and others.
A month ago I changed out my Stryfe motors for these https://www.pololu.com/product/611known as the Solarbotics RM2
Today I received some batteries I ordered from wish (I'm sure you know where this is going by now) and installed them. (4 of them)
Here is the motors reference information.
Name: Solarbotics RM2
Form Factor: 130mm
Volts tolerance:9v max
Max amps draw: 300mA
Here is the batteries reference information.
Name: UltraFire 14500 Rechagable Lithium AA Battery 1200mAh 3.7V
Form Factor: AA
Amps: 1200mAh
Volts: 3.7v
I got them running for about a total of 15 seconds before smoke started coming from the motor cage and it stopped functioning entirely.
I'm not 100% sure why they failed. But my first guess would be that I didn't realize that batteries in a series increase voltage. So 3.7v x 4 batteries = 14.8v (right?).
Assuming the above statement is correct I over volted the crap out of them and it caused the internals to fry.
So i guess I'm asking if someone can confirm or explain what I did wrong here. I'm sure its the voltage. Also funny story, the stock switch didn't fry.
