150ah lithium battery upgrade 2005 Bailey pageant. Advice

[GarryH]

Good evening all. Looking for some advice to install a lithium battery to my caravan. I only want to use it for the 12v system so not interested in the full inverter setup for off grid.

Question is what exactly do I need as research on google and YouTube is baking my brain? My towing vehicle is a 2021 Kia sportage diesel hybrid

I changed the following:
The on board PSU for a Victron IP22 15amp charger, which gets very little use.
The solar controller for a Victron MPPT 75/10 and the 30watt solar panel to a 130watt one.
This pretty much keeps the battery fully charged even when we are away using the van.
As for charging from the car when I first set it up I tried it without a B2B charger and the car charges the battery at 14.4v - 5 amps. If it had been any higher I would have fitted a B2B charger. On a long journey (200 miles) this can cause the battery BMS to shut down but that's what it's designed to do.

So just set it up and check voltage and current from the car (can be done on most battery BMS) if it's below the figures above you are good to go. If higher fit a B2B charger.

Exactly which Pageant (which is a range of models) will get a more details response.

Discussing caravan market Lithium batteries with Powrtouch's technical a couple or so years back they were guarded about these in the context of powering their movers. Basically they had had problems with them and recommended keeping to LA.

That's as said from at least two years back, by now I would think "we" have accumulated a lot of real life experience in that aspect.

Have these adopters of Lithium found any problems in that regard?

One aspect I found in reading/studying the battery specs was those of the time seemed specified for up to 100A output, whereas the mover I had was specified as drawing a peak of 120A. That in my case was only a paperwork issue as in part because of that I a stayed with another LA GEL.
My mover application is probably quite demanding, close to the limit of the units capability. Indeed later it mechanically failed and has been replaced with a more capable one.
