iCharger sparks when connected to battery problem

I have an iCharger 1010b+ and a 2500mah 3 cell LiPol battery
I connect the charger to the battery with clips.
Sometimes when I connect it, there is a a spark, indicating that the charger is drawing significant current. Why?
Surely the charger should be in a open circuit (aka Z-state) while its waiting to charge?
Anyone else seen this spark?

yes always get spark proof connectors aka explosion proof...http://www.amazon.com/Cheerwing%C2%A.../dp/B00QSVOBIC

Yes but the charger shouldn't spark when connected if it is in z-state, or close to it.??
IE it shouldn't be pushing or drawing enough current to spark?

Are we talking about connecting the charger to the source battery or the battery to be charged?

There's a rather large capacitor on the charger input, with no current limiting resistors. Some sparking while connecting to the source is normal.

No, it is when connecting the battery to be charged to the charger that sometimes I see the spark.

Many chargers have a capacitor on the output side, depending on the size of the cap and the voltage of the pack you can get a small spark. You could connect a multimeter between the battery and charger and see if any current continues to flow if you're concerned about it.

I get a small spark sometimes when connecting a batt. Nothing to worry about.

Connect the battery according to the sequence in the manual on page 6:
First connect balance cable, then main plus, then main minus.

You should see the spark when connecting a 6s battery, but like you it's not every time.

I don't connect in that order when parallel charging high amp packs, it can make the balance connectors spark.

On parallel charging, you could connect the first battery in the same manner. On the others then only the mains first (for the equalizing current).

I always get a POP when connecting my 6S packs to my PL8. Scares me but it is normal. If a charger breaks due to this it was designed incorrectly.
