Update. I went ahead and ordered the fixed voltage booster. Due to the current exchange rate ( 1 AUD = 0.65 USD) it comes out to 49 USD landed (free shipping basically). I'm spending free money on this probably unneeded fuse, so don't @ me.
Subtotal: $50.00
Shipping: $22.00
Grand Total: $72.00 AUD
I'll post some before/after shots of the V readings if I see a change.
