Anyone who has charged a lipo without a balancer circuit or other gizmo has charged through the discharge side... perfectly fine. Maybe a bit better using their attachment because it'll keep individual cells in the proper voltage range but certainly not mandatory.
Balancer circuit can be easily replicated by making up a balancing jig to enable you to check the voltage of each cell and charge if necessary to bring it into balance.
