Operate a 12v/6Amps air pump, with DIY battery pack?
I have an electric air pump and i want to operate it with a battery pack (for camping purposes, away from any kind of electricity source).
Its a 12V/72W pump (works with car lighter connector) so by my poor calculations, i need something that can give me 6Amps for at least 5-10 minutes.
I have a lot of 18650 batteries in my disposal, so i thought that i maybe can put together a portable battery pack, so when i go camping for example i can carry it with me.
My circuits design skills are... nonexistent...
My DIY skills are reasonable... so my questions are:
1) Is it possible to create something that can provide at least 5-10 minutes operation, once per every charge?
2) If yes... can you please tell me or point me at the right direction so i can accurately calculate the amount of batteries that i need and the proper way to connect them?
3) or... any other easier "portable" solution? for example something lighter and cheaper than a motorcycle battery...?
Thank you for your time! :)
