Im fairly new to electronics. I've completed the Arduino starter kit's 15 projects and now I'm making a 4 wheeled robot for some purpose.
I'll be using 4 12V DC motors along with an Arduino Uno/Mega and HM-10 BLE breakout board for BT.
Optionally I'm thinking to add addressable RGB LED strip too (5V APA102).
To make all this work onto a single chassis for PORTABILITY I need a battery pack that ensures (Highest to Lowest Priority)
- Maximum speed for motors
- Maximum operating time
I found that Lithium-Ion or Lithium Polymer are good choices due to lightweightness and high mAh capacity.
But I don't know what kind of C rating I would need. Also I don't have experience with those batteries (I've heard they cause fire if charged improperly).
Also I'm wondering should i power my Arduino and BLE module from 12V output (stepped down ofcourse to 5V and 3.3V) or use a separate one(Battery Backup System for Raspberry Pi and Other 5V applications)?
Here is the site from where I would probably buy: link
As of now thinking to buy the following:
- LIPO Safe Bag (30cm x 23cm)
- Dont know what C rating I need for my project? Need suggestions on that (Lithium-Ion Rechargeable Battery Pack 11.1V 6600mAh (2C) OR Lithium-Ion Rechargeable Battery Pack 11.1V 4400mAh (2C))
- Li-Ion / Li-Po 3A Balance Charger for 2-4 Cell Battery
Any guidance is appreciated. Thank you :)
