|  My battery arcs when I plug it it, am I doing damage?
Running dual fxrs, a cc bec and a 3s lipo with deans plugs. Every time i plug the battery in it arcs at the deans plugs, am I doing any damage? Maybe if I run an on/off switch on the bec along with the switches on the fxrs? Just curious, Thanks -Matt |

That is normal, don't worry about it. It is the capacitors charging up.

I no it's not harmful and it's normal and all that, but I've tried hooking up my deans at an angle when installing a batt. for example approach with the Neg. side making contact first and then the pos. I've noticed less popping (arcing) this way. It doesn't take a lot of angle, just touching one side slightly before instead of both simultaneously. hope that helps  |

You get a better spark using bullet connectors. Not a problem it's just the capacitors saying "I'm here for you." |

I get a nice spark along with the "pop" sound every time I plug in 6s. But never much with 3s.

Holy crow, 12s must take a wicked expensive charger! I try to plug the negative bullet first to reduce arcing. |

You should see the arc on 20s lipo. That is what my ebike runs. With normal power capacitors it is pretty loud. With a larger bank of low ESR caps it will pretty much destroy a plug in one shot, so we have to use a precharge circuit to avoid such welding events.

Here is a ride on 18s. Holmes Bikes 66v ride - YouTube I killed that battery by leaving it plugged in by accident, drained it to zero. So now I ride 20s.

Any bike with a Ammo Can bolted to the handle bars is ok in my book.
