Search results for query: charging leisure battery from EHU

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...

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...

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...

The breaker would be one of the electrical circuit breakers on the front panel. You can access them directly without the Powerpart being opened. If you refer to the manual (link I added earlier) you'll identify it as the 6Amp beaker, as all that breaker does is provide electricity to the...

Yeah @roadtripper that was my thoughts also, the MCB I just wasn't comfortable with. In the end I binned the supplied MCB and installed the charger under the passenger seat with a 60amp midi fuse next to the battery, and the negative on the factory ground also under the passenger seat, I then...

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...

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...

One thing to consider here is what you are doing is charging the starter battery and then your DC-DC charger cuts in because it sees a battery it thinks is being charged by the engine. So the profile and multistage charging will be looking after the starter, and reacting to it's state of...

Given all the other complexities VW have built in to the T6.1 model, the engine run (alternator charging) signal seems very crude. It did make me wonder whether the presence of this ‘signal’ voltage will ensure the correct operation of the CTEK DC-DC / MPPT charger I’m planning to fit and the...

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...

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...

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 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...

Should be ok. 8A will cover the loads you mention, provided you use EHU to charge the portable power station and not the 12v conection. You will find the 120w panel is a bit lacking for a charging the PPP, it will extend your run time a bit. So for now get it hooked up and see how you go.

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...

It's great! I run my Lavazza coffee machine and the milk frother off it. I charge phones, speakers and MacBook off it when away. I can also run the fridge from it. I will be testing it very soon charging our soon to be delivered Estarli e20.7 folding bikes. I have a leisure install but it will...
