Typically I paid 30 quid more for one a week or 2 ago as it didn't look like any stock would be available for weeks, if not months!

I just got my order in for one. The question now is where to fit it.

My camper was supplied with the factory-fitted auxiliary battery under the passenger seat and it seems a bit cramped under there so I’m wondering whether it be better to put it under the driver’s seat where there’s much more space and air circulation. This means removing the split charge relay and running cables from the relay feeds along with the battery -ve through and along the channel across the floor and under the driver’s seat. This looks straightforward enough... I hope so anyway.

You'll need to fuse the feed from the SB anyway, so snip the relay (and fuse - it's after the relay) off, add a midi fuse at that point, then run your 2x or 3x 16mm² cables for the IN, GROUND and OUT feeds on the Orion XS across between the seats.

Actually yours is a T6.1 so might be a little different to my T6.

I believe the 6.1 has a split charge relay with bolted terminals

That seems to be the case. I was planning to use the engine battery feed with the bolt hole terminal to connect to the midi fuse that I’ll fit (as @TallPaul_S mentioned). The other cable will be connected to an insulated bus bar terminal block fixed under the seat. That way I shouldn’t need to cut off the factory terminations allowing it to be returned to a factory install should I ever need to.

Nice, if it's got an M5 terminal on there then it'll fit straight into a midi fuse holder. You might need to cut off the ignition signal wire though as goes straight into the H port on the Orion with a bare wire. If course you don't need to use the signal wire.

I see on the information sheet the SCR has M6 terminals which should make it simpler… at least I hope it will be. I seem to remember @r00ps had to open up the hole to fit a CTEK 250 and that has M8 terminals. I need to do a bit of research to see whether I need to connect the signal wire feed to the Orion XS but looking at the user manual it seems to suggest that the unit doesn’t need an engine-run signal connection.

Picture from @r00ps thread on upgrading the factory install to a CTEK

T6.1 factory aux battery split charge relay upgrade & solar panel install.

Hi, I had the factory fitted aux battery ( under a single seat with swivel base ) fitted to my T6.1 with the intention of using it as a camper leisure battery. After getting less than impressive performance and reading about how the split charge relay is a pretty bad charging method I wanted to...

Woo hoo, my Orion XS has come. I ordered it late on Wednesday afternoon and it was delivered lunchtime today (Friday). Superb service from 12Volt Planet.

Judging by its small size (it's only 1.5" / 39mm in width) I reckon I should be able to fit this under the passenger seat (between the end of the battery and the seat base side panel) after all. If I can it will certainly simply the installation.

Yeah there's loads of room to slip it down the side of the battery, even a big 230ah seatbase one.

Do these run hot like the older versions, or has Victron sorted it out with the XS?

Nowhere near as hot, the efficiency is much much higher (less efficient = more heat) and there's no need for a big heatsink. However, they can still thermal throttle, it'll just ramp down the amps if it does this. I've had mine at 50a and never noticed this.

its gots hot if running at full whack 50A for a long time, ( ie 3hrs drive with a low lithium battery)

but turn it down to 30A and its cool as a cucumber.

much better than the previous TR which got silly hot.

Love ours, yes as stated long drive it gets hot, but I have fitted mine next to vehical battery and it gets enough air supply to keep it cool enough to touch, even here in Spain. Can post photo´s if needed
