Question for the BMS/electrical gurus:

For some reason they put the main battery terminals extremely close together on the outside of the case. 30V is not a lot, but the higher the voltage, the more it can jump. Lets say a little dirt/condensation/grease is allowing a very very small amount of current to flow on the outside of the battery case between terminals. How would this affect the sensing function of the BMS? I would think it would be a slow draw, always pulling the battery voltage down slightly, requiring - more charging?

I am not an aircraft mechanic. Do normal 28V aircraft batteries put their main terminals an inch or two apart?
