A while back, Radio Shack introduced micro RC vehicles called Zip Zaps. Not long after introducing those, they introduced a line of monster trucks that in my opinion, were way cooler than the Zip Zaps SE or even the original Zip Zaps as these monster trucks could drive for a much longer time and they can drive on carpet, tile, and most any surface you can think of. They’re also 4WD, which is really cool!
After playing with one for a while with the stock motor, I had to have more of these, and along those lines, upgrade them w/ Radio Shack’s upgrade kits. I also discovered some mods that were available for the monster trucks to make them not only faster, but make more efficient use of the stock battery.
The mod I’m going to detail facilitates neither of those end results. Instead, this mod attacks the charge level of the monster truck’s battery, thus translating into longer run time, especially for older, kinda worn out batteries.
