My question is about the maximum charge voltage of a Lithium-Ion cell.
I have charged my battery pack with 8.4V (the maximum voltage). The pack is a Samsung ICR18650-26F. The pack has a smart controller with a maximum voltage of 8.5V. This is 4.25V per cell.
I read about this that exceeding 8.5V can degrade the lifetime of the pack. However, the manufacturer don't clarify this detail.
My question: Will this voltage damage the cells or this within the tolerance range.
