DIY Battery Pack to power Arduino Mega

Hello!

I plan to build a battery pack with 6 Samsung INR18650-30Q's in a 2s3p configuration. Since they are unprotected cells, I was wondering what kind of battery management system I would need to use that works with an Arduino Mega. Also, would I need multiple or just one for all 6 cells?

Thanks!

You could use the mega itself to monitor the cells tension and a mosfet as a switch, but it's not the safest way (i won't build my safety on the bug-free software assumption). Easier and also cheap: a simple BMS.

Why not just a pack of 3 x AA alkaline cells (4.5v) feeding into the 5v pin?

Or a pack of 4 x AA NiMh cells (4.8v) feeding into the 5v pin?

The reason I am building a battery pack is so that:

  1. I can recharge it
  2. I need it to have around 10,000mAh because I am powering quite a lot.

Thanks for the idea though!

How do you plan to recharge the pack? Do you have a li-ion charger with balance feature?
