Why does being unprotected matter?
An unprotected cell has no built-in circuit to stop over-charge, over-discharge or short circuit. Use a protected charger or BMS board and add a fuse to the pack, since a shorted Li-ion cell can overheat.
Can I use it in a power bank or an Arduino project?
Yes, through a protected charging board and a suitable boost or buck converter. Because the cell is used, keep discharge currents moderate and stay within the protection board's limits.
