AGM VSR B2B , T5 2011

[emjga]

Folks

When I bought my T5 2011 , converted in 2013 , about 3 months ago.
I knew the leisure battery was done in and not really holding its charge.

It was a 80Amp Wet lead acid battery.

Since I will be mainly doing off Grid , Moving on each day / night
I bought 2 X 100Amp AGM (Anything bigler would not fit in the space)

The Van has a VSR (I assume) as there is nothing the leisure battery area.
I know VSR dont work very well with AGM

Shortly I am going to install solar and a suitable solar controller that supports AGM.

Should I be changing out the VSR for a B2B charger as well (A lot more expense and I suspect will have to run a new cable from the starter battery )
Or just leave the VSR in place and use the solar to top up the AGM

If it makes any difference I live in Scotland , Aberdeen
Most of the trips will be in Scotland so shorter sun hrs in the winter.

Any thoughts

Thanks

Matt

Definitely look at fitting a dc-dc charger.

Even though you've got T5 and a VSR etc you will be better off with a proper battery charger.

Solar will help obviously while the sun's out get a bigger panel as you can afford for the roof if and look at getting a decent mppt solar controller.

Next time you think about upgrading the batteries look at lithium.

Posting pictures of your setup and van so we can see what's what.

Thanks , that is the answer I was expecting.

Think that is going to be my next little project.
Need at least a 200 watt.

Not sure about just one big panel (More expensive) or 2 X 100 watt
Then have to decide parallel or serial
Live in Scotland and will be mainly in Scotland for trips.

Just replaced from single 80Amp wet lead battery to 2 X 100Amp AGM
Did look at lithium but just could not justify the cost.
