That's 3S3P = 9x 18650, a bit too many 18650 for my comfort. I am not sure they have a circuit for individual cells, since my SSK-33 battery doesn't have them. (Does have a protection circuit for the whole pack)
Anyway, I will wire this individual cell protection circuit into the pack, so each cell will have over charge, over discharge protection, plus there is a tempreture protection as well.
Combine that with only running 3x18650, I think my battery pack will be as safe as it gets, much safer than the stock form 6x18650 w/o individual cell protection.
