I bought a 2016SR recently. First 100km no issues. Now there are several Sevcon 0x45C3 Low Battery Error and the bike is shutting off. Battery was 93% SOC last time. Any ideas?

I would start my checking the large bolts (five) on the Sevcon motor controller. Perhaps one of two is loose that comes from the bike's battery. Two come from the bikes's battery, the other three go to the bike's motor.
You get to it from under the seat, very rear of the bike.
If no trouble found there, I would try to measure the battery input voltage there on the Sevcon. If seems flaky, measure it under load with the back wheel off the ground. But if the bike isn't running, I assume you will see the problem right there and then have no need to lift up the rear wheel.
It's high voltage, so be careful, as the bike must be on (contactor closed) to check the voltage there.

How long does it take for the bike to shut off? Where are you reading those sevcon errors? Could you post either the MBB log snippet you're using or a log of the startup process for the bike.
Be careful touching the controller bolts, over torquing or under torquing them can cause thermal events.

"Thermal event" aka 'fire'.
