John:

Remeber to disconnect the lipos when not in use. Lipos will continue to discharge if left connected. Like I said in a previous post, the circuit is complete when the Deans connection is made and there will alway be a slight current drain. That is what generates the spark. Spark is always generated when there is a bad connection and the electricity attemps to complete the circuit by jumping over the bad connection. When you attempt to plug in a Deans connector, you have a bad connection until it is plugged in all the way. It should be noted that the current drain is still there even if the capictor is fully charged or discharged. If the lipos are allowed to discharge below a certain level, they are ruined.

Experience teaches us many lessons, if you have a bad connection with any household appliance, the plug will get hot, melt the plastic and eventually short out and blow the fuse, that is if it doesn't burn down the house first. With RC, if you hold the Deans connectors apart, and the current attempts to jump the connection, your Deans connector will get hot, and the copper terminals inside will turn black. Deans connectora are all about making a good connection to avoid the sparking and burning of wires when there is a bad connection.

I had to respond, because the capacitor explanation does not apply to all connetions, and all connections will spark if the connection is not solid.
