    Hi , I have just fitted a sterling b2b charger on my elegance 821 and am now wondering if I have done the right thing .

    Not knowing if it had something similar in the first place as standard !!

    It's also got a couple of solar panels on but I have no idea of there rating how do you find that out. The controller is very basic and I was going to replace it with a MTTP controller and may be a battery monitor.

    One last question I have 2 110 ah battery's and the van came with 2 new 90 ah battery's can I use them together or would it be best to have the same ah.

    Many Thanks Matt

    best way is measure the panels you have and find similar sizes on ebay yes you can use different sized batteries to make a bank
    i would wait and see if you need an mppt controler mine is basic and works well if you need more power its more cost effective to put another panel on if you have the roof space but depending on the size of the present controlloer that may need to be replaced anyway if you add more

    4mm/S cables are standard in Autotrails.. that should give you an idea.. The most you are going to dray is proly 10 or 12 amps..
    But !
    The Sterling B2B is proly gonna stick some serious amps in to the battery bank, so while massive great thick battery cables are proly OTT, certainly worth improving on the standard ones fitted to the Elegance

    I take it you have an Elektroblock, some models have the equivalent of a battery to battery charger an no way should you fit an additional one, others just have a straight pass through and it will be OK.
    Best to email Udo at schaudt: Udo.Lang@schaudt-gmbh.de

    The difference in size won't be a problem but the batteries should be of the same type, your van will have had either Gel or AGM batteries as OE can't mix standard wet cell with them.

    Also I wouldn't start the engine until you have established which Elektroblock you have if you give us the model number may be able to help. Most of the later vans in the Hymer group have been fitted with the cheaper Elektroblocks so shouldn't be a problem.

    Not sure but I think the 220 has the feature built in @JeanLuc will probably know, if you email Udo you will get an answer in an hour or two.

    The EBL220 has an internal circuit called a D+ booster but I'm not sure what it does. A&N Caravan services state on their website that some EBLs have a boost circuit in them to speed up charging from the alternator.
    I would email Udo Lang and ask his advice regarding the additional B2B Udo.Lang@schaudt-gmbh.de

    Hi Guys many thanks I have heard from Udo and he has sent me the instruction manual. There is a switch on the E-bloc to switch between 1 or 2 additional chargers. I am still unsure so will have a chat with Jon at thetford at the weekend.

    Many Thanks Matt

    Split your battery bank Matt.
    Let the electro bloc look after one battery and split that battery from the others with an ign switched 70 amp 5 pin relay.
    The B2B can look after the remainder.
    It's the easiest way to avoid electro bloc confusion!

    The Auxillary Charging inputs (blocks 1 and 2) and the related selector switch are for use when there is one or two extra Schaudt mains chargers linked to the EBL220. This is to cope with large battery banks - e.g. if fitting three or more habitation batteries. The additional chargers concerned are models LAS1218-2 or LAS1218-Bus. I think the EBL220 would probably work with the LAS1218-2 as the 'Bus' model is more recent and I believe is designed to work with the latest 'bus-wired' EBLs. Here is the catalogue entry for the older version (2014 catalogue). These units are mains powered and act as an integrated charging supply with the EBL. They are not related to alternator charging or a B2B unit.
