Battery profile help please

Hello

My son is converting a 2015 Ford Transit to a camper van. We believe it has a "smart" alternator.

He has bought a Victron Orion-Tr Smart 12 12 30 charger and a Varta LFD 180Ah leisure battery. We've connected the charger to the 60A "customer connection point" (CCP).

Would one of the standard AGM deep cycle profiles be appropriate for this battery? If not, what would be appropriate values for a user defined profile?

If we start with a standard profile, is it possible to monitor the graph in the app and use it to make adjustments to the profile? If so, what is the strategy?

Thanks in advance for any advice. Sorry, we're new to all this!

Doug

You would need to see what varta recommend for the battery it should have the information on the side of the battery or on a spec sheet that came with the battery.

Usually I pick the profile then tweak the voltages that way you have the corect absorption time and charge profile set.

14.2 v is probably the charged voltage. Again just check the info.

Also make sure the 30A charge current is also not too high for the battery as well by using it's c rating.

Example a 190ah battery with a C10 rating should only be charged max with 19A

Hello Alexandra. Thanks for your reply. We've looked everywhere we can think of on the internet for charging data for the Varta battery, but can't find anything. There's nothing on the battery itself or the (tiny) booklet that was stuck on the side. I've sent an email to Varta technical support but no reply yet. If you know of anywhere we might get the charging information could you please let me know?

Regarding the charge current. The battery has written on it "180Ah(C20) 153Ah(C5)". I presume this means that if we charge at 30A we'll get 153Ah, but if charged at 9A we'll get 180Ah. Is this correct? Are we ok charging at 30A?

Many thanks.
