Connector Mania: JST-XH

The small connector on most batteries is called  a JST-XH and is used for balancing.  A 2S pack will have a 3-wire connector, a 3S pack will have a 4-wire connector, etc.

Two adjacent wires will connect to one cell.  The first and last wires will be connected through all the cells.

Batteries can be charged through this connector up to a current of 3A.

The crimper seems to be $480 (!!?!?!??)  Some possible replacements are mentioned here.  Magic search keyword seems to be "D-SUB/DOUBLE-D SERVICE TOOL".
