Help & Support Robot Parts

Hi,

I purchased a Arduino 2650 mega with tank tracks, I’m looking to power it with a rechargeable battery and charger here are some required specs, would you have anything in this range?
lithium battery with 18650 Core. Output 12V-13V 4A,not exceed 14V.
Thanks,
Damny

What motors are you running? Are you planning on seperating the Arduino’s power source (battery) from the motor controller/driver and motors?

This is what I got it’s mega2560, motor controller, WiFi, camera, and arm with tank chassis.

I would like the battery to power it all if I could.

Which motor controller did you go with?

I’ve never heard of that board, nor can I find any information on it… I’m assuming that you’re running servos as your drive motors?

I got the robot from www.xiaorgeek.con it’s called a Arduino Th robot, I believe it is a China based board, no distinguishable markings on it.

I can take some pictures if that helps.

I’m not well versed on LIPO batteries, I predominately run NiMh… I’d take a look at this link:

Do any of you have input for this? It appears that they are requesting 12V Lithium battery. I thought lithium was 11.1V? Am I reading too much into this?

Hi @bmoscato, you are right.

We can offer https://www.robotshop.com/en/18650-battery-cell-holder.html with https://www.robotshop.com/en/lg-18650-37v-3500mah-lithium-ion-battery-cell.html

3 of these would give 11.1V and 4 would give 14.8V …
