Search results for query: charging leisure battery from EHU

The light in the top picture shows the alternator (via the starter battery) is charging the leisure battery. The voltage readout for the batteries is useless when the engine is running as they just show the voltage from the alternator. You need to turn everything off and leave for about an hour...

Unless you have an inverter fitted, which will change 12v into 240v, you will only have live 240v sockets when connected to EHU. All your 12v stuff runs from your leisure battery-lights, fridge, tap, diesel heater, usb sockets etc. When on EHU your mains charger will charge the leisure battery...

What’s involved with this? And can it be bought as a kit? I’m coming from caravaning and what a super basic system. I have thought the portable battery pack is the way, but why I’m at carpeting point in the build I am thinking a basic EHU system is going to be worthwhile? Many thanks

This is my first post and I’ve just started to convert my t6 kombi, so far I’ve had it all insulated and sound proofed, vapored and carpeted. I have had an 100ah leisure battery with victron Bluetooth b2b installed under the drivers seat. And the next step is to have EHU installed. So my...

From our experiences we now have a good idea what happens when the batteries are being charged. Thanks for the investigation

Note that you don't need the isolated version in a van as it's fine to use the body as a common ground, the isolated versions are for more marine environments (where currents in a metal hull will cause galvanic corrosion) or coach-built vans. The isolated will be fine with both grounds on the...

need to crack on and fit mine got distracted with a projector supply mod

Yep, a decent charger of some sort sounds beneficial. Question is whether you want a EHU charger, bypassing the Sargent, or add a DC-DC charger which would charge from alternator whenever vehicle is running. How does it currently charge from alternator, is it a split charge relay, a DC-DC or...

I've got/had a similar setup, now upgraded to the following ... Kept: EC155 Sargent for DC distribution (essentially it's now a glorified bus bar and switches) 2 x 100W Solar Panels Removed the Sargent capability to charge the leisure battery (removed the fuse and as a double check ensure...

I am sure that the section that houses the hob, sink, fridge, gas bottle/water bottle (next to fridge) is standard width, then from the gas bottle cuoboard rearward is the slimline bit to allow for the bed width. I have a 110ah Lifepo4 leisure battery, a 2000kw inverter, and a 260w solar panel...

Thanks. These look interesting, but it is probably easier to plug a separate charger in to the dash 12v socket as @Bargy62 suggested. I intend to make a dedicated EHU cable to the length needed for my carport and leave it there permanently.

The one off the inverter is taking the 12v from your battery and converting it into 240v. The other is obviously taking it direct from the 240v EHU. As long as you have a battery charger that charges your leisure battery when on EHU I’d guess you should be fine using both/either. The charger...

There is plenty of information on this forum in regards to how to do the wiring in our vans. I've learnt a lot and done a lot of reading on here. I have noticed that there are no diagrams showing a physical layout of components so figured I'd upload one to hopefully assist other. My set up has...

That's what I did (although with a Noco rather than CTEK) the first time I charged at home. It shut off all the habitation area lights and pump though, so I've been charging separately. It seems that this is normal though, so hopefully not an issue.

Another thought, could I hard-wire a charger/optimiser to the leisure battery, power it via a 240v socket for better charging on ehu?? Remove charger fuse from Sargent unit?. This would still allow Sargent control board to switch 12v etc on? Seems a very easy, obvious solution and i could fit an...

Did i read somewhere that the BMS will only charge the Starter battery to 80%. I leave mine on trickle charge from my solar but i cannot recall it ever getting to full charge

I did some investigation with mine this morning (2023) and worked out what is going on. The 12V “engine run” signal (black wire) that feeds the VW split charge relay does not work quite as I expected it to. When you connect a charger to the starter battery, the increased voltage wakes up the van...

So I’m using my set up in the field for the first time. Gorgeous sunny day, about 22°c, no shade on the panel, but according g to the Victron app I’m only getting 5-6w from the panel and it’s in float mode which I guess means the leisure battery is pretty full. My fridge is on EHU, so with no...

if you plan on going for Ablemail AMT12-2 then it sits alongside the DC-DC charger. it relies on the fact that the Leisure/AUX battery is being charged by either Solar or EHU and will effectively "back-charge" the Starter battery - so if you have some Solar or EHU it will work fine . . the...

Unless it's configured in a non-standard way, the ablemail should only be directing charge to the starter when there is excess available I believe? This should cover scenarios where the leisure battery is full, or close to, but there's still plenty of either solar or EHU available. Do you have...
