I'm working on a medium sized robot project with multiple arduinos to control stuff. I've been planning on using a lead-acid battery pack, but then I was given 10 working and identical Asus laptop battery packs rated at 14.8 V 4400 mAh, and one old Asus laptop.
I opened up one of the battery packs, because it was bad and it has a 4S2P battery configuration and a protection board.
Can I hook all of these battery packs in parallel, or will power leak between the battery packs, and is that be a problem?
Is there alternatively some 4S20P or 3S25P battery pack with charger I can purchase to put these batteries in?
(I do have a step-down converter that will provide the Arduinos with the right voltage, regardless of input voltage up to 36 V)
I tried to ask a similar question on electrical engineering, but ot was deemed off topic for the site.
