Hello, I'm very interested in robotics but have not messed with the electrical side before. After ordering some parts, I was unsure of what specs I needed for my battery.

Brushless esc - https://hobbyking.com/en_us/turnigy-plush-10amp-9gram-speed-controller.html
Drive motors (x2) - https://www.amazon.com/gp/product/B071VNC352/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Brushless motor - https://www.robotshop.com/en/uav-brushless-motor-a2204-14-1400kv.html
And a sabertooth - https://www.robotshop.com/en/sabertooth-2x5a-rc-driver.html
The original battery I ordered - https://hobbyking.com/en_us/turnigy-1500mah-3s-25c-lipo-pack.html?___store=en_us

If someone could explain what I need to do to figure out all the information (for the battery) that would be great!
Thanks in advanced

Hey


Also, you really should not use a Sabertooth. They are notoriously unreliable and can fail unexpectedly.

What is a good alternative?

What weight class are you building for? I'm almost certain the battery you have is huge and heavy given I think you're working on a 1lb bot from those parts. If so, you may find those drive motors a little fragile. I run a 450mah pack in my 1lb bot and its tons of capacity, 300mah should be fine.

For now I am just trying to learn my way around this stuff with a practice robot but once I'm comfortable with it I was going to get a lighter battery and do some antweight.
