Search results for query: charging leisure battery from EHU

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...

1,Adding another socket to run off EHU = pretty straightforward or easy depending on your skillset. 2, Swapping to Lithium, = also pretty straightforward or easy depends on your skillset, please take time to read through the forum, the subject has been covered to the Nth degree and all the info...

Lead acid batteries are optimised for broadly two uses; either for providing very high current for a brief period (starter) or low current for a long period of time (leisure). Any battery isn't like a fuel tank, you can never fill a battery back up to where it was as it's a chemical reaction...

Firstly, my apologies to those who have asked for pics and my seemingly unwilling to send them. Apart from access to the backs of the batteries and the the ability to put a probe on the terminals, everything else is buried under the two front seats and without removing them, no pic of any use...

PMS3 confusion cropped up in a recent thread. They key to understanding it is that it is a very old design built for caravans. So, essentially, you never want the switch in "car" as that will drain your starter battery, you want it in "van" (caravan i.e. leisure battery). Seriously never use...

Hi, I am having a van day today as it is the first time since i bought it last September that i have had a chance to really explore it! It has a PMS 240v - 12v system (Black box under seat with fuses in) with a leisure battery and a 60w solar deck. If i understand this correctly, the PMS unit is...

Hi pal. I get charge when the van is running, have no solar as not really needed. Have a fridge running, lights and usbs when out camping. If we have hook up we have a tv too. The ip22 is only in use when hooked up to EHU. But max we would be off grid is 2-3 days so nothing major. I have...

While it's not ideal you could also have a dedicated hook up converter that swapped the line and neutral conductors - but have a really big label or marking on it so you know what it is and don't use it for "normal" use. There is a risk plugging power packs into the EHU socket. They normally...

Anything below 11.99v is considered dead flat. And looking at your plots above there are many occasions where the battery has dropped below 11.99v. Even down to 9.0v. which is very bad. Is either the battery is not being allowed to fully charge before discharge cycles.... That battery is a...

Thanks, great info re chargers. I don’t seem to suffer from the 80% LB charge issue for some reason. A run will charge it to 12.9v and I’ve not seen any sign of it discharging it to 80%. The starter battery however only seems to go to 12.4v but that is probably past its best anyhow due to age...

The problem is that Westfalia fit them thus - 1x75Ah as standard (although the one in mine is 70Ah) and if a second leisure battery is requested, it is a 95Ah battery that is fitted. Apparently with all the wiring and associated electrical gizmos tucked under the seat with the smaller battery...

I decided not to remove any of the panels and disable the charger itself. I plugged the EHU into the mains and used a DC clamp meter to identify the cable from the charger that connects to the leisure battery. I then disconnected this cable, labelled and made it safe. The EHU is unaffected and...

I agree it would seem like there is a shortage of skilled auto electricians and an abundance of carpet and ply to cover piss poor workmanship.

Had a similar experience with mine when I found the existing system fitted by a so called professional conversion company (now gone bust!) was not suitable for the van and wasn’t lithium capable. I changed pretty much all of it and fitted solar and relocated the battery and chargers to under the...

Hoping someone can help I’m going crazy! VW t6 - my van battery went totally flat - trickle charger and started fine been fine since. The EHU won’t charge anything not even leisure battery. I’ve had the van EHU changed still nothing. While trying to get it to charge and messing about the MCB...

Did you manage set this up? I've got the portable Renogy. Seems like a good quality panel and a handy smart bag for it

so, what about the Elephant in the room? - 12v Leisure electrics and Solar.? Nope, there aint any, not a sausage, nothing, diddley Zip. ++++++++++++++++++++ that means ill have to fit the lot. well be going with: DC-DC charger under seat, Lifepo4 under seat, MPPT under seat, Inveter...

That’s brilliant, thanks for taking the time to explain! So, the plug sockets will only work on EHU? I also have to take the screw out fuse for the fridge from the PMS3 to turn the light off. I just put it back if/when we are going to stay out over night. Does the fridge work from the van or...

For D+ see this thread, short answer just pick up an ignition live from the dash fusebox https://www.t6forum.com/threads/t6-looking-for-the-d-signal-wire-in-a-t6.4458/ Many DC-DC do not require an ignition feed by the way, they can normally detect engine running from monitoring the voltage...

Their instructions are not very clear and contradict themselves depending which version you look at! As far as I can tell the AMT will also charge the SB once it drops to 12.2v (or 12.1v in one document) as long as the LB is 0.2v above the SB. This will stop once the SB gets to 11.5v (and/or, if...
