Battery discharge

I didn't want to give up that storage space under the rear seat, but I suppose a second battery is on the shopping list.

I have just the single battery and noticed that after a couple of days camping that the battery was down to 53%.

I didn't take any power from the vehicle, maybe opened the doors about 10 times per day. The internal light was set Auto off.

It would have been good to have had some kind of mode that didn't turn a load of things on when the doors opened.

Portable battery box

Not sure what's available in the UK but this sort of thing is what we use

Maybe a portable power station for camping and a Noco battery starter in case you flatten the battery for longer camping trips.

I do always carry a battery starter just in case, the portable power station is perhaps a better solution than filling the vehicle up with batteries!

Portable power station such as Ecoflow or a Bluetti with solar panels is the way forward in my opinion.

I would use a condensator-based external starter.

Why?

You do not need to keep it loaded. You can carry it years in your car without taking care about. As long as your car battery has 3 Volts left, which is really low and the battery is crap then, this thing works.

Those types are effectively just a big capacitor which can get a charge from even a depleted battery. This charge is then used as short burst to start the engine.
The conventional type has a lithium battery which can give a short boost to a flat battery.
The capacitive type has several advantages, primarily it doesn't need to be kept charged. Double the price of course.

Thanks. I spoke to a Defender tdci owner yesterday and they had used a jump starter on his extremely depleted battery and it destroyed some component but he didn’t say which type of modern jump starter he used either lithium nocoboost type o capacitor type

I’ve been told you should always charge or jump start directly from the charge points in the engine bay and not directly on the battery. This may be the difference.

When you jump start with a second car the electronics on the source generator can be damaged....many say let the engine idle or give it some more revs to support the source battery, but that could lead to a broken regulator. That happens, when too much power is pulled.

Have in mind, when you start your car, the generator is not running, as well. So you don't need that.
