I am contemplating installing a Smartshunt 500A to monitor my house battery (and possibly running battery on the alternate channel). I've looked through the manual and it specifies that the 2 bolt terminals on the unit are M10 in size. This would correlate to a 3/8" lug. So why on earth would Victron make the studs this size? It is standard practice that positive terminals are sized at 3/8" and negative terminals are sized at 5/16". At least that is the case in the US. In wiring this I would start at a 5/16" (aka M8) terminal at the battery, step up to 3/8" (aka M10) on both Smartshunt terminals, then back down to 5/16" at the bus bar. This would require custom cables of course. Is this really the way that Victron designed this unit, or am I misinterpreting something?
