Batteries Got Exhausted in Few Seconds

I am building myself a simple robot car.

Simply, an A10 Olinuxino board  (my first false start because of the hard work of interfacing the ultrasmall 0.05'' pins header) interfaced with a Pololu Dual Motor Driver (https://www.pololu.com/product/2130)

To move forward, backward, left an right, I use a simple Web Interface which sends Ajax commands to a Python Web Server I wrote.

For example, to move forward, I write 0 and 1 to GPIO 3 and GPIO 2 respectively. The motors spin, but after few seconds the batteries seem exhausted. 

I am using 4 1.5 NiMh 4800mAh batteries which drive the motor part of the Pololu. The A10 board has its own power supply.

Does anybody know what is the root of the problem?

I bought the batteris in a local store. They are, as written on the metal label, “GodP AA Ni-Mh 1.2V”.

AA Batteries

NiMh are nominal 1.2V. I typically see 1.35 when freshly charged. The 4800mAh sounds like Chinese specs. See:

for some hints.

Hello, I think the problem

Hello, I think the problem is with the battery. Getting a good quality battery should not be too much of a hassle. I usually get mine online from WIN SOURCE . Their products are always genuine. You just need to order online and you are good to go. Check here >>>>>http://www.win-source.net/category/all
