Anyone know if there is anything commercially available to prevent the spark when plugging in hv batteries?

Quoted from Castle Creations website...dunno if this helps.
"3. When I plug in my high voltage battery pack (4s-12s lipo, 12-20 NiMH) into my Phoenix HV or Phoenix-125, etc. controller there is a large spark. Why?
The spark is your friend. If ever you plug your pack into your controller and you don't see the spark, contact tech support at
[email protected] or (913) 390-6939 and send the controller in for repair. Your capacitors will need to be changed. NEVER fly if you do not see the spark, especially with high voltage applications! The higher the voltage, the bigger the spark should be. Remember, the spark is your friend!!!"
This is a controversial subject. The damage to the capacitors with the sudden inrush as they are charged along with the actual damage to the connectors. The only disadvantage to running an anti spark setup is that the auto cell detect can pick up an incorrect cell count.
I use an anti spark on my sukohi (6S) and have never had a single trouble with it.
Get an "armsafe" device and put a 2 ohm, 5 or 10 watt resistor across the connectors of the device..
