Multi charge leads
I was charging an 800mah 2S battery via the JST connector on my multi-charge lead. After the charge was finished, I went to unplug the battery and dragged it toward me over my bench, when the lipo started fizzing and smoking. I suspect the Tplug that wasn't in use at the time shorted out on a pen clip. The effect is as good as shorting out a Lipo across it's terminals.
The terminals have melted and the lipo has puffed so I've junked the battery. To avoid this in the future, I took an unused T connector and covered the terminals in silicone. When you look at all the leads on the harness, if a short is going to happen, it's going to be on the T connector with those exposed terminals sticking out.
Silencing the Swallow 2 AC/DC
The buzzer on the Swallow charger is very good at it's job of alerting me to when the battery is finished charging with a very loud BEEEP!. The problem is, I have a 6 month baby girl trying to sleep half the day in an upstairs bedroom. You should see the looks I get from the wife when this thing goes off.
I've tried containing the noise by putting it in a metal filing cabinet and closing the drawer but the sound still gets through. So I decided to remove the buzzer from the board.
I'm sure I have voided my warranty but now I can charge batteries to my hearts content without waking anyone up
