Search results for query: charging leisure battery from EHU

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...

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...

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...

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.

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...

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...

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...

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...

Spot on thanks mate, much appreciated. Yes I have access to 240v all year round. Might be a daft question but would not just plugging in the EHU not so the same thing as a smart charger? I was just thinking of adding a BM2 monitor as well. Sorry if this is an ignorant question be I've no elec...

Ecoflow and other portable battery banks have definitely disrupted the traditional leisure battery approach. Based on your use case I would just go as simple as possible - EHU and a 240v oil filled radiator. I have a Kombi with very minimal 12v needs (Wi-Fi, CCTV camera, occasional iPad...
