Core Skill: Electrical Prototyping
If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Just What I Needed
I order this battery for a project that I never finished from last year. It arrived on time and was the right about of mAh I needed for my electronics. Previously, I had a 540mAh battery hooked up to my circuitry, but that was the stand battery that came with a mini screen. Long story short, it was too weak after having added more components to the screen so I needed a boost in power. After checking how much power I would need with my ohm meter, I decided on this one. So far it's been great! It's small enough to fit inside my project and definitely has enough power to run for a few hours based on what I have hooked up to it. Overall, I recommend it if you're looking for a good lithium ion battery.
