I have come to a conclusion that I need help with this haha.
I have looked around many places, from places where you can build a custom battery, to places where you buy already built batteries. Rechargeable, not rechargeable.
Let me begin by letting you know I know some knowledge of electronics, but not a lot. I understand that I want a higher mAh, and a good amount of volts. Well… What I need is about 10-20 volts.
I think I am going to run the arduino on a separate regular 9 volt battery.
Anyway back to my question.
Where to buy?
How much are we talking? I have seen a wide range of prices.
What kind should I get? I am using this for a robot, mainly to power motors. But I may use this battery for something else if I get bored of the robot.
