AGM Battery Query

What is a PDU charger, surely that is not the make? I doubt very much it will automatically set to AGM but without knowing the make and model it is difficult to verify.

PSU?

Sorry, I assumed that as both Bailey and Prima Leisure (and other companies) refer to it as such, everyone knew it is not a brand name but stands for Power Distribution Unit.

Thanks and it would appear to be produced by the BCA Group but I cannot find any technical information about the product. Suggest you contact >BCA< and ask the question.

The handbook for my Bailey motorhome clearly states that the battery charger can charge AGM batteries with no adjustment. (I have recently changed from a wet Banner to a sealed AGM) As far as the Truma controller is concerned mine allows adjustment for different varieties of batteries including AGM.

David - I have read the book for my Unicorn IV, specifically pages 48 to 59, starting with the heading Mains Unit (PDU) and ending with good/reasonable coverage of the SDC10. The small entry regarding the fitted charger part of the PDU is included. I cannot see any reference/mention of AGM batteries. My faulty SDC10 was correctly set up for AGM.

Peedee - Exactly, like you I cannot believe it will automatically set itself to AGM. Thanks for the info that it is a BCA product, email sent but they close at 1200 Fridays so not expecting anything back until next week.

I'll keep everyone interested informed!

At last, a brief reply from BCA--

Thank you for your email. "Yes,  as long it has a BMS between or charger and the battery."      I think most of us will take that as a NO its not suitable, unless we have all fitted an after market BMS into the system somehow.

I wonder if there is a difference between caravans and motorhomes in terms of charging equipment? AGM batteries are very heavy which might put people off for that fact alone whilst perhaps not as critical in a motorhome?

David, the 5 or 6 lb weight increase (on average) doesn't really bother me and I actually bought the AGM without doing my homework. Stupid Boy!  It was only afterwards I realised the fitted  BCA charger could shorten the life of my expensive mistake. With that in mind I am removing the charger part of the PDU and installing a NOCO Genius 2 which is definitely AGM compatible.
