If you have a tank that performs poorly, it is probably the batteries inside the tank itself.

I have a tank that did not work well. It was only a few weeks old, but, after charging with the stand-alone charger, the tank would perform okay for about a minute. Then it would have a severe turn to one side during 'straight' running. I thought one of the motors was bad. The tank would not turn in place, forwards or backwards. Very slow operation, no power, and, overall performance was bad.

Then I replaced the two cells inside the tank. Now the performance is excellent. Straight forward operation is much improved. It operates better in every way, and better than new.

I think a lot of tanks may have the same problem. The type of cell used in the tanks is not known for reliability.

If anyone thinks that their tank may have this problem, please let me know.
