After 1 hour of searching for the drivers of the programming cable for Win7 x64 and tinkering with T6Config, i finnaly got my mixing working right.

I was so happy that i started to chase my dog through the house to get used to drive with one stick. The robot was really really nippy, but the speed started to drop fast, and after 2 or so minutes the robot barely moved.

I have to wait until 6 in the afternoon to get my multimeter back and check power consumption, but my motors stall at around 10A, so worst case the two sould draw 20A. By my calculations i got this:

Battery outputs 1.8A for 60minutes
Motors draw 20A (worst case scenario)
20A is greatter than 1.8 12 times
Battery duration will be 12 times less
60/12=5
Even with the two motors stalled, the baterry should last 5 minutes.

So, i thought that the problem should be that the battery wasn't fully charged.

My baterry is a 7.2v 1800mah ni-cd pack and my charger outputs 1000mah, so i use this formula e saw on many RC forums to calculate charging time:

1.4 x (baterry mah's) / (charger ma's) = charging time in hours

1.4x1800/1000=2.51

2h30minutes of charging time.

Is this correct or should i leave it charging more time?
