Hi board members! I have recently build a circuit to 'sense current' of a Li-Ion Battery using ACS710. But, upon done wiring on perfboard, i found that all pin 1 - 8 is shorted together, is it normal? AFAIK, pin 1-4 is shorted for I+ while pin 5-8 is shorted for I-, but continuity test for pin 1 and 8 shown shorted.
 

They are internally connected together through a copper loop so they should measure as shorted.
The load current (or a proportion of it) passes through those pins and the internal circuits measure the voltage dropped between them. The voltage drop is proportional to the load current and it is this that gives the measurement at the output pin.

Note that perfboard is not a good construction method, even for prototyping, in this kind of application.

Hi,

I assume the datasheet tells you the expectable resistance.
