hmm.. how come the 150mah batteries r smaller than the 50 mah ?

I just noticed today after my car did the slow down to mud speed today after my new motor that the 150 mah battery is smaller than my 50mah battery ? Also, the 150 wasn't sitting snug in chassis. I cut off a paperclip and wedged it between the wall of chassis and the batt tab and bingo ! car was running good as new again ? why ? is the new tomy 70 mah battery the correct size ? am thinking of trying that one. Has anyone else noticed this ?

I don't know the reasons why the 150 is smaller than the 50... but I know that you didn't need to add the paperclip. With the battery removed, you just have to take a small screwdriver and bend the contact inward towards the middle of the chasis so that it will have a nice fit for the battery.

I tried that at first but it didn't last. The tab eventually bent back after some use and some collisions. The paperclip is more permanent. The tab can't bend back.
