BMV Shunt wiring question (does this look correct?!)

Hi folks, so i'm looking for advice on my wiring schematic that I have drafted for my van conversion.

I'm fairly confident with everything but would really appreciate any comments/feedback.

I've ran the negative from the Orion-Tr smart DC/DC and the negative from the mains charger out to the BMV shunt so these can monitor the incoming load. Is this the correct figuration?

Thanks in advance.

No. Battery on one side of the shunt and everything else on the other. As wired, anything connected to the Lynx will bypass the BMV and cause SoC errors.

Ah sorry just realised you had amended the picture! Thank you makes sense now! So aside from that everything looks like it should work ok?!

I'm in the U.S., so my response is based on conventions here.


50mm wire is about the same as 1/0. If that's marine wire, it may be rated for 285A


If that's the case, then your 300A fuse is fine, but it needs to be Class-T


I see nothing else of concern.

@satoshi Did you bother to read the quick install guide that you can find on the VE website?

I hadn't seen this Martijn so thank you for referencing it, will be sure to read through. I plan on getting really stuck into the manuals before installing but just wanted to be clear on the setup before i purchase everything. Thanks again.
