So, I've done a lot of research with regards to using this unit and changing leisure battery to Lithium.

As I understand (confirmed by apuljack) the unit can be used in Gel setting to charge Lithium batteries for short periods of time (whilst on hook up) but not for longer times like overwintering due to the high float voltage. On hookup EBL 30 would still trickle charge the engines AGM too but on the GEL setting?

Would this do harm to engines AGM? Can this be disabled with fuse removal?

I can/will add solar/controller with Lithium specific charge settings for when off hookup, I think that will work OK??

The only problem I see is when the engine is running, it's not possible to disable engine charging/linking of leisure battery, Apuljack tell me the unit will have to go back to them to have this disabled. A simple fuse removal is not possible.

If we buy a Hymer with the Electroblock battery booster the problem should be solved as this unit has a Lithium setting.

Help and advice please.
 
I disabled the EBL 30 internal charger by removing the fuse.

When on EHU I have a Victron IP22 lithium charger connected directly to the lithium leisure battery.

I have also installed a Votronic VCC 1212-30 30A B2B which is wired into the back of the EBL - its very simple to do and the manual has a diagram that explains it.

The EBL starter battery charge is only a trickle charge at 2 amps it won't harm the starter battery.
I agree about not using the EBL to charge the lithium full time. You can just pull the 20 amp fuse to stop leisure battery charging, the starter will still charge.

How did you disable the original charging of the leisure battery whilst the engine is running. Apuljack tell me it's not possible.

I have the manual, which page has diagram?

Easy pull the 50 amp fuse by the starter batter or disconnect the starter battery cable from the EBL.

Strange. My Sterling Power documentation says that the float voltage for the lithium batteries is recommended to be 13.8v. My NDS Energy meter says that the EBL30 (on GEL stting) gives a float voltage of 13.6v. and it all works well.

The EBL 30 in our Hymer Exsis has the cable from the starter battery disconnected. It came that way from Hymer . Everything works OK.

If you buy a new Hymer, it should come with a B2B charger (which by-passes the EBL). Ours did.

does the EBL99 have a separate fuse for the Leisure battery ? I will check in the morning in the cab

Does the fridge work on 12v, if the main 50amp cable is disconnected where would fridge get power from with engine running?

If I could find a van with the Hymer B to B fitted that would help at it has a lithium setting.

Seperate wire to the starter battery and a 20amp fuse by the starter battery.

Hymer fit the Schaudt B2B depending on the van a 25 amp or 45 amp, yes it has a lithium setting.
It wouldn't, as the relay in the EBL feeds the fridge from the SB
Nope nothing to do with the the starter battery feed, fridge will work and starter battery will charge from EBL.

Still confused, please be patient, so fridge will still work as it's fed direct from engine battery but the relay that operates it is powered by the EBL??

Disabling EBL charging of leisure battery (on hook up) is a simple fuse removal?

But LINKING/CHARGING of starter to leisure battery (with engine running) is what I need to disable, Apuljack say unit has to go back to be modified, there is no simple fuse removal. I'll add the diagram if someone could highlight please.

If you are getting a newer van, will it not have a 12V compressor fridge? Our 12V compressor fridge runs from the leisure battery.

Schaudt don't advise long term charging on EBLs. I spoke to them directly, not hearsay.
Also the BMS in the battery will turn charging off when full so it's not an issue leaving a float charge as it won't get to the battery cells once the BMS detects its fully charged.

Going second hand, the vans we have looked at have three way, we paid a deposit (ML-T580) and then noticed water in garage and battery box overflowing with water, unsure if they will fix it and give us a good warranty. So refunded for now.

There are two cables from the starter battery a big one that goes into the back of the EBL and connects to the split charge relay inside the EBL. The smaller wire connects via the front of the EBL to the fridge relay which switches the fridge to the starter battery when the engine is running and to the Leisure battery when the engine is off. The smaller cable also carries the charge back to the starter battery.

Yes.

Here’s the cable at the back crossed that you disconnect I’ve done this with our electrics and left the front alone basically not using any charge functions from EBL and using Victron Multiplus and victron DC-DC chargers instead it all works fine👍😊

The BMS will not switch off Float Charging.

The BMS only disconnects the cells for over or under voltage, over or under temperature and over current protection.

Yes and the BMS should be treated as a last resort, far better to use correct charging regimes.

I've avoided all of these issues - 3 yr old Hymer with standard factory set up and 3 X AGM 95ah by adding in a BOS LE300 lithium extension battery. Took me 30 mins to fit, no adjustments or alterations to anything else. Works very well - just enjoyed a 15 day tour of Scottish Highlands with on 4 nights spent on campsites with EHU. I don't think I saw my batteries drop below 13v the whole time.
