Hey, that's my Chinese shunt!
Even at 300A I'm a bit concerned. As mentioned earlier, this concern is driven by the shunts used by Victron et al. However those have probably been sized very conservatively for monster power-boats with all the accoutrements of a modern-day condo. My 30' sailboat, mostly running a few led lights and old B&G instruments along with the Rpi, hardly competes. Nevertheless, I'll throw an ammeter around the main lead during cranking to see just what's being drawn.
If I have enough capacity, I'll monitor the entire system from the low side.
