Our potential is based on experimental energy transitions covering $v=0-34$, and very high precision theoretical long-range constants. It provides high accuracy predictions up to $v=100$ which pave the way for high-precision long-range measurements, and hopefully an eventual resolution of the age old discrepancy between experiment and theory for the $\\mbox{Li}\\left(2^{2}S\\right)+\\mbox{Li}\\left(2^{2}P\\right)$ $C_{3}$ value.
