Re: [electricboats] Battery Fusing

Good idea.  Should have thought of that.  The controller has a 500A fuse.  So if I match that at the battery I will protect the wiring and have enough capacity to match what the controller should max out at. 

I have found these options so far (thanks for suggestions...)

Here's all the Blue Seas options

Still looking for more...

The SEVCON GEN4 controller can limit the battery current and in any case limits the motor current.
 
You can take a look at the fuse integrated in the controller:
- 48V size 2 - 275A max motor - 250A fuse (x 48V = 12 kW)
- 48V size 4 - 450A max motor - Fuse 425A (x 48V = 20 kW)
- 48V size 6 - 650A max motor - 750A fuse (x 48V = 36 kW)
 
An additional fuse on the battery bank protects against short circuits in the wiring.
