Easy Lithium upgrade to help others, then upgrade two.

[G-A-R-Y]

To help others searching,
I've been testing (18 months) the lithium (Roamer 160) fitted under the bonnet initially along with Orion XS B2B instead of the dumb relay, along with any possible issues with VW control panel.

All works well, the hottest the battery got to was 42c (France heat wave 35c) the control panel is always 100%. I also disconnected shunt under bonnet with no issues.

A few weeks ago I had an upgrade, we fitted a dummy battery under the bonnet (the battery connections act as a bus bar for the Orion and make it look original, we fitted a 300Ah (Fogstar) in rear cupboard along with a Victron Multiplus 2000 inverter. This charges the battery at 80 amps.

I also had a second MPPT fitted so I can plug external solar panels in at the rear doors.
The folding solar panels make a lot more that the roof mounted. I have a simple "charge, off, Inverter" control panel, pointless adding Cerbo.
I'll add loads of pictures, work was done by Brento Campers in Plymouth.

I went with car Electric (Hamburg, Germany). Their system is not cheap but it does work flawlessly. We have done many extended trips (4 to 5 weeks) and never had to use the EHU. Why VW don’t offer lithium as an option is crazy.
