Quick shunt mod question

I'm modding my controller looking to go from the roughly 15 stock amps to ~30 amps. To do this I'm assuming I need to cut the shunt's resistance by 50%. I could do this by adding a second shunt of a known resistance, but couldn't I also do this by reducing the current shunt's length by half?

It looks to me that I could quite easily bend down the center of the shunt and bridge one end to the middle of the shunt with solder effectively shorting half of it.

Anyone try this? and reason I shouldn't?

Thanks in advance!

Re: Quick shunt mod question

Possibly dumb question but ... specifically which vehicle are you talking about? A lot depends on which vehicle & controller you have. Maybe others on the site know what you have, but I don't.

FWIW What you describe sounds about right.
