Speaking of battery monitoring, ever since I’ve had my @RoamerBatteries I’ve thought it would be neat if the BMS app could be viewed on CarPlay.
Now with the latest iOS upgrade Apple have introduced widgets to CarPlay, I checked today to see what the fuss was about and was pretty pleased to see my BMS app there.
Now I can check the status of my battery and switch on the B2B on the way to the campsite if it’s looking low.

@Skyliner33 can you see if this works with the victron connect app? Or vrm app?
Why do you manually switch on the B2B ?
I believe it can be set up as a widget but doesnt have the full functionality. but I haven't managed to get it working yet.

Oh not on the app, just a simple switch at the base of the seat.
I put an labelled isolator as close to the starter battery as possible for emergency use only, I would expect anyone but the owner to find a fuse to pull.
Good question. I’ve always just let the solar keep the battery topped up.
I was thinking that would be healthier fo the overall battery life, a lighter charge that would allow the battery to run down slightly on cloudy days, vs 50a b2b pumping in every time I drive.
Have I invented that logic, should I just leave the b2b switched on?
My take on it is (and I could be completely off the mark) just leave everything connected, mains/solar/B2B, and assuming that they all have the correct charging profile, everything sorts itself out. All my kit is Victron, and shares the same custom profile I made using the recommended settings from my battery manufacturer. I never have any input whatsoever, the system is completely autonomous. When I plug in to the EHU, the mains charger kicks in, likewise when the sun shines or the engine is running, the respective chargers are always on. If I leave the van plugged in at home and the mains charger is on “float” or “storage” and I start the van, after it’s booted and done it’s checks, the B2B (Orion) will also go into float or storage, effectively shutting down. The whole system requires zero human input, the LB is always charged and ready to go and has worked perfectly for the 5 years it’s been running. The battery is still reporting 99% capacity, it’s never shown 100% even when new, I think that’s a quirk of the software.
There's some logic behind it, if you're not using a lithium cell they prefer to sit at between a third to half full rather than be held at full charge.
But you'd need to do that with all the chargers and with the lifecycle of a decent top end battery it's probably not worth the hassle.
If you store your van over winter and don't use it much maybe.
I do think there is more credence to not charging at the full 50A every time the engine is running, personally I'd set the charger back to something like 30A and only go to flat out the weeks I really needed to stuff charge in because I was camping off grid.
