  We study the interaction of maximally-charged dilatonic black holes at low
velocity. We compute the metric on moduli space for three extreme black holes
under a simple constraint. The Hamiltonian of the multi-black hole system of
$O(v^2)$ is also calculated for the $a=1$ and $a=1/\sqrt{3}$ cases, where $a$
is the dilaton coupling constant. The behavior of the system is discussed
qualitatively.
