How do you have it wired? Make sure none of the batteries ends are touching the charge contacts (if all in chassis). Make sure that the battery in the battery holder has only one end touching a charge contact. I solder mine together from the battery in the holder (-) to next bat (+), that bat (-) to next bat (+), that bat (-) to negative charge contact (on drivers side of car). I use electrical tape on one end of each battery, the two in the front of the chassis I tape the back ends ( towards charge contact) wit two layers of tape. I tape the battery in the holder on the negative end with three layers of tape. I also put another layer of tape across the top of the positive charge terminal, to prevent anything on the pcb from touching (I had one completely melt on me from this little detail). Make sure the solder points on the pcb do not touch any batteries or contacts in the chassis. Also, if you get batteries too hot while soldering, they will fry. Check each battery by itself if you can, I use an old chassis with a motor wired to charge contacts (kit racer chassis), I can even leave the batteries soldered together if the solder joints are not too big. You want to check that each bat will charge and then run a motor for a while. If bats wont charge or only run the motor for several second, then the bat is likely fried. Hope this helps, good luck.
Also I have found that some motors suck with three cells, you may try a few different motors first. The fastest motor I have in single cell cars is a serious dog in three cell cars.
