I'm planning on using 4 Tesla battery modules (5.2kwh, 24V, 250AH each, wired in series) for my build but first I need to purchase the right fuses, cables, and circuit breaker to make sure my system is protected.

In order to find this out, I calculated the amps flowing through my system by dividing the total watts by the total voltage (20800/96 = 217 amps). With this information I decided to use 4/0 AWG cables, a 250A 160VDC circuit breaker, and 300A 700V semiconductor fuse to protect the cables from overheating and the other parts in the EV from blowing.

I was looking at some Tesla battery modules to buy and came across this in one seller's description, "[The Tesla batteries] are rated at 500 amps, 750 amps peak...

**Maximum Discharging Current (10 sec.):**750 Amps." This got me double thinking my calculation and if the wire gauge, circuit breaker, and fuse were appropriate for this application.

Does anyone have any insight to give me on this? Will I have 500 amps or 217 amps flowing through the cables? And most important of all, will the wire gauge, circuit breaker, and fuse I chose be appropriate for the protection of my system?
