Can I charge my caravan battery from my car alternator with a DC to DC while idling?

If there are people prepared to pay what a new top end touring caravan costs these days, then they're hardly going to notice a £500 battery.

Batteries are not normally supplied with a new caravan.

Most caravanners will go to camp sites and plug in the mains.

Would you buy one ?

OP is in Australia, if the flag is correct.

They might not have the same facilities on caravan parks as we do in the uk….

Ie, do they go “off grid” for extended periods and are only able to charge while driving or PV whatever.


We should get an update overnight.

I'm never likely to buy a new caravan, or a new car either, as I far prefer other people to take the main hit of depreciation, but if I was paying out £45,000+, I'd expect a battery to be included. Even if you do plug in when at a site, a battery is still needed for stops while travelling, and to power the mover while siting the van or hitching it up.

I'm sure they would throw one in if you spent that amount, but I doubt they would even mention lithium.
I wouldn't be surprised if the majority of people even knew that they existed.

It's only an option, I would have thought most people wouldn't want to pay the £300 - £1000 for a battery.

But LifePo4 batteries are far far superior to Lead Acid... and considering the life cycle of LA, will be cheaper. For a boat, it's a no-brainer to fit Lithium these days.... for a Campervan, I guess it would be too...

If I was buying a caravan/campervan... I'd want to design and install my own electrical system... that way, it would be exactly what I wanted, rather than a 'built down to a price' half baked solution.

It's a no-brainer if you can afford to do it or indeed have a need to do it.
Lead acid batteries have done ok for the last 150yrs and continue to do so.
