Hello, I have a 10s1p battery pack and 2 of the cells have gone bad (puffy) — 3.7v 6.4ah 230wh.
I’m getting conflicting answers on if I can just remove the last two cells, leave the last 2 battery leads disconnected, and still be able to run my ESC.
Dumb questions:
Does my ESC need 10x 3.7v to run correctly or can I just use 8?
For the 10s BMS, what is the rated A for this pack?
How do I find out the discharge rating C of these cells?
This 10s1p is straight from my board so it would be factory setup. Would there be anything I can look at on my board BMS/ESC or cables that gives away this answer on discharge?
Hmm well there’s three wires coming out it looks like, so probably it is wired for discharge… Maybe you could look up the part number and see if you could find the bms to see what kind of discharge rating it has
He could unpopulate the 2 now unused circuits to make the bms believe it’s an 8s bms? Or is there a software side to making that happen? I see so many Chinese bms have unpopulated series and always wondered if I could populate them to have a bigger bms rather than buying the exact same one with more populated circuits
Image to visualise what I mean by bigger bms with unpopulated circuits
Can I use these cells to make a new 10s battery pack with my original 10s BMS? They fit the dimensions required in the cavity of the board, which was hard to find, to be honest.
3.7v 6,000mah discharge (1C)
I want to explore all the options of reviving my board with a new battery pack before giving it up for parts. I’m being optimistic and taking this opportunity to learn the basics of LiPo battery and battery building. I appreciate the help from the community.
You don’t want to mix li-ion cells of different ages, but I’m not sure on pouches. I’m guessing frowned upon, but need a smarter guy like @ShutterShock to weigh in.
