got my new LRP Automatic Pro Reverse ESC today I have ran 2 batteries on it already on, the second battery it just suddering stop going in reverse

when I do it just does the normal green display and at full power no light in the manual it says if there is no reverse or brake the pinion or gear ratio is to big the esc was a bit hot so im leaving it to cool off I tried it again and it still does not work why is this happening? I have a 13 turn motor and I have tried a stock motor and still not working.
