Schaudt Elektroblock EBL 29

[Nigel Crompton]

I'm acquiring a used 'van that's fitted with an EBL29.

Can anyone tell me the subtle difference between this and the very similar EBL99, please ?

The manual contains this intriguing paragraph:

"Lead-acid batteries can be swapped with lead-gel or AGM batteries. However, swapping from lead-gel or AGM batteries to lead-acid batteries is only possible in certain circumstances. Contact the vehicle manufacturer for more information."

There is a single 95ah Varta AGM battery (I assume original from 2015) connected to a non-mppt solar charger with a diddy 100w panel. I'm looking to replace the single AGM battery with 2x90ah (sealed, but I'll need to vent them) wet Varta Type LFD (as I have in current van).

Anyone here been this route, AGM->wet lead acid ?

Cheers 'n' Beers

I find this bit of the manual confusing but the ability to switch the ebl over to lead acid is clear. If your new batteries are happy to be charged at 14.3V/13.8V I can’t see the problem. It may well be about going from batteries that don’t need venting to ones that do but you seem to have this covered.
I went the other way to LiFePO4 which are not covered by the ebl. Schaudt advised me to pull the 20A/12V charging fuse and use an independant charger.
An email to Udo.Lang@schaudt-gmbh.de if you are not sure will probably solve the issue. He corresponds in English and is very helpful.

So stick with AGM or Gel! Dont see the issue.

Not a lot, there are several models of the EBL99 some are almost identical to the EBL 29 on others as far as I can see the differences are:
On the EBL29 if no other source of power the fridge will be powered by the leisure batteries, the only obvious difference there is a connection for the starter battery on the solar connection block on the EBL29, only the leisure battery on the EBL99. The later EBL99 had these functions.
No difference in the charging.

It would seem that the caution in the EBL manual is there to prevent clueless people replacing AGM batteries with lead acid without making arrangements to vent the new batteries externally.

As my batteries are adjacent to the Truma I think I'll just stick my vent pipe into the Truma's exhaust ....

You will have to move the switch on the charger from gel to lead as it charges differently

The warning about flooded lead-acid batteries is a German thing. Hymer originally fitted gel (and later AGM) for safety reasons in case the van turned over. Hence Schaudt referring to the need to check with the manufacturer if moving away from original equipment. In practice you can use what you want but I would not use AGM with an EBL 29 or 99 as they are not really suited. It is good practice to vent batteries; my original gels ‘gassed’ when a cell failed at the end of life. Since then I have used sealed flooded lead-acid and ensured they are vented through the bottom of the battery tray.
If changing the battery type selector switch on your EBL, make sure you switch it off first.

I wouldn't use AGM under any circumstances absolute rubbish. I'm a big fan of Gels.
