Guys,
I've been flying ECL for almost 3yrs and noticed a small spark (very small not a flash) when plugging in the battery to the charger. This hasn't seemed to bother anything but I was wondering if it actually does shorten battery life or cause/contribute to the slight puffing of some battery packs?

I have sometimes plugged in the balancer first then the main plug and it seems to reduce the sparking. Anyone notice this and is there a better sequence to plug into the charger?

Best,          DennisT

I don't know about the batteries and chargers for electric motors.  But, for my car battery and pit box battery, I hook up the battery first, then plug in the charger.   Even disconnecting, I do the charger first, then the battery.   But, with the new fangled batteries, I would suggest reading instructions thoroughly.

Came across this link for an anti-spark set-up.

That MGM system is too complicated, too many connectors, while that Jeti is OK, but I prefer connectors like shown on that MGM system, but it does not allaow those resistors like on Jeti picture ... so I simply install resistor directly on female connector like MGM picture ... simple and well working

BTW that system from Jeti is sensitive to overheating, it need carefull soldering, or it is better to cool that side of connector with resistor while soldering
