Thanks MOG! I was actually hoping someone would have this stance, should we raise the platform a bit then?

Once again I am seeking the collective knowledge and imagination of this forum :D We have until the 6th of Dec to lock in out panel designs and i cannot decide what to do with the massive windows we have spec'd with regards to overhead storage around the seating area. The dilemma is as follows...

Our Tender has arrived! Modding time starts as soon as the snows! And I still need to find a 2" hitch rack ?

Thanks Neil!

Right! I didn't even notice it was a button! :LOL: I left it running then tilted the cab to find a failed gasket. managed to stop it by loosening the throttle cable a wee bit (my exhaust / engine brake button is broken for now, as well as my lockers and low range, must be an airline cut...

Check the YouTube channel mentioned in previously. Also another issue is insulation and drafts in the lifting roofs.. everyone in euroland cuts the doka to make a 1.5 cab.

Yea, check the YT videos from the German explorer magazine. Their company truck has a self made lifting roof and it blew off in a storm ? I think only unicat still do this (and the only ones I know to do it very well). But it's all in the XXL weight class which tell you the extent of the extra...

Atkinson Voss in the UK do it like and a couple of other MB overlander truck houses in Germany also, it is a mixture of bosch benching the injectors and fuel pump rebuild, but there are difference stages to this approach also. They tune the turbo for more boost throughout the curve to match the...

The suspension available for these trucks has pretty high applicable gross weights. For instance the aftermarket parabolic spring I fitted are either 4/3+1 Springs designed for rear axle loads of between 6-8 tons (metric). You aren't dealing with fine tuning down to the kg here and suspension...

Hey guys! Doing some system cataloging so I can get the workshop #todo list ready for when we ship the truck to the UK, I came across this wiring on the compressor hose and didn't manage to trace it back anywhere, anyone have ideas? Looks like it has a spark plug fitting on it...

Jon, I was thinking, why not just use your MPPT controller to charge the starter whenever you need a bump? I suppose it already has the charging profile and the wiring would be simple enough.. Alternator charging is such a hassle in general, I want to forgo it completely if possible on the house...

Another vote for getting the singles on fast, I can give you some supplier details who ship with tires, balancing etc from Germany. With TUV paperwork!

A 1C discharge from the cells themselves sure. But most BMS´s can't and don't do 1C discharge rate. The most problematic issue with the direct wiring approach would be charging curve of the nominal voltage. The voltage curves for the different chemistries are totally different, not to mention...

This is a really dangerous approach IMO. Those lithium cells will push as much current as they can, you need a charge regulator.

As mentioned by @DiploStrat protecting the house bank discharge is key, to only fill the starter bank when you have at least nominal voltage in the house bank using the Vstart/shutdown trigger metrics in the Orion. I suppose you could go as low as 3.0v per cell and the unit charging profile will...

You dont need an external relays, there are 2 ways to activate house -> start circuit charging, either using the program engine detection with your custom voltages on the alternator line into the DCDC line or a combination of the L-pin override. you do not even need an isolator as you can use...

Hi Jon, The Victron smart DCDC chargers have programmable relays you can use for those proposes and also ignition / startup / voltage sensing, all programmable. You will probably need an isolated unit and combine the voltage sensing (alternator to house) with the relay (use the circuit on the...

Nice catch, the QUCC have 2 or 4 possible rely configurations for high and low charge protection independently. Quite attractive and well thought out. The REC BMS might be the answer however for full victron GX device integration with SOC and cell information without attempts to program...

The article was very informative, but the writer misunderstands quite a few concepts when it comes to solar calculations and the basic technology, as you said, a baseline for most core aspects.

Today is BMS day, I will test 3 BMS units with canbus communication to see which one passes all my requirements with regards to basic operation with a mind to building the firmware to communicate with VEbus victron GX control. First is the latest JDB FET based board with 200A continuous...
