Hello, I've made an electric longboard. I'm having problems with smoke coming from the battery charger - even before the charger is pluged into the mains.
On the outside of my board I have a 3-way DPDT switch, a 6s balance input socket, an XT60 socket and a voltage display.
The 3 way switch is On/OFF/Charge.
(I haven't glued the ports in place yet hence the wonky looking XT60)
I use 2 x 3s batteries wired in series. I use a twin pack balance charge lead to convert the two 3s balance leads to a 6s balance lead.
The battery is connected to the "O" on the switch. The VESC is connected to the "I" on the switch. The XT60 socket is connected to the "II" on the switch. The voltage display is also connected the "II" on the switch.
So when the switch is set to "O" nothing in theroy should work.
Today for the first time, I connected the battery charger to the XT60 port and connected the 6s balance charge lead from the battery charger to the port on the longboard....before I even managed to plug the charger into the mains there was smoke coming from the charger near the fan area. (I use a turnigy accucell 6 80w charger).
What I can't work out is why when the DPDT switch was switched to OFF there must have been power going to the output socket of the the battery charger. How can a switch that is set to the off centre position divert power through the charge cables connected to the "II" terminal?
Any help or ideas would be gratly appreciated. I really want to get this sorted before I connect my very first VESC. I DO NOT want that smoking!!!
Cheers.
