Hey guys, two part question.
tl;dr - 2x 7.4v 700ma batteries. Can I hook them up in parallel? Is there any power filter/smoothing/protecting stuff I should put into the circuit?
I have two 7.4v 700ma aircraft batteries that I'm going to use to power my version of the Chopsticks bot that I saw on Make's website, it's an eight-legged walking robot using 24 mini servos for the three-jointed legs. It's all being controlled via an Arduino Mega 2560.
First off, is it okay to hook two of these batteries up in parallel as a power source, assuming they are equally charged? And if I do this, is there any kind of protection circuitry that I should built to protect the batteries/Arduino/Servos from when I inevitably do something really stupid?
Disclaimer: I'm still very new to electronics and my understanding of electricity is only slightly better than "Voltage is like water pressure, amperage is like water volume!" Pretend you're talking to a fifth-grader and I should understand you fine
