Search results for query: charging leisure battery from EHU

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...

I understand your thinking but I think you may be thinking too hard! :D LB isolator is primarily for totally isolating the LB for maintenance or the rare occasion you may want to turn the leisure system off completely. Solar panel isolator again is for maintenance and to prevent solar...

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

The battery's a TNPower TN-LFP12100 bought from TravelVolts in 2019 You helped me 3 years ago with an issue I had with the shunt which has been fine ever since I carried out your suggestions. Leisure Battery Monitoring The battery has switched off a few times in the past but because I always...

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...

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...

Yes it’s set up to charge leisure battery so looks like I only need to wire a panel into the ctek to top up my leisure battery when off grid.

Right. I’ve been putting this off for a while but as it now affects my Dometic fridge and we’re looking to go on a trip to Europe this summer I need to tackle this. Been putting it off because electrics (and plumbing for that matter) are like the Dark Arts to me! So please bear with and excuse...

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...

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

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...

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...

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...

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.

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.

Just some thoughts on the Ablemail AMT12-2, with a LiFePO4 leisure battery... If I set the AMT12-2 to mode 3 for lithium, it will only trickle charge the SB if the LB voltage is above 13.5v. Which is 100% capacity with zero load, or actively being charged by solar, EHU etc. Which, is great...

Yes you can do that.... No issues. When on EHU the starter battery will charge.... Then the Renogy dc-dc will switch on to charge the LB. I call is the Auto vsr feature..... I don't a post on it, show on my HIDI thread. With smaller chargers I noticed cycling on and off.... But ultimately...

Hope it is OK to resurrect this older thread: When I camp I'm always on a site so no problems with EHU for charging overnight but on days out (when I might be parked up but still at the van for a few hours) I've either got the fridge on (which on a hot day can use a surprising amount from the...

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

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...
