My system has a single EG4 LLv2 48V battery.
For safety, I was considering adding a battery fuse in addition to my main breaker off the battery (not the battery switch/breaker). as I have seen recommended.
After doing some calculations based on my max inverter surge watts/current, additional constant DC loads, BMS short circuit current, etc, I thought 125 or 150 amps would be a good choice, class T.
But then I remembered that the battery switch is itself a breaker. Here it is:
This appears to be this exact breaker, available from SS separately:

So the question is, do I still need/want a fuse? If so, only for a quicker trip/blow when I hit that current? Or am I needlessly over thinking this? Thanks for any thoughts.
