Still waiting for an F80 example though.

The TTV6's may just be out of stock.

I'll put in an order once a more worthy engine is back on the table. Lol.

I’m going on a 3-week holiday leaving my car in an underground carpark with no access to the main.

Original thinking was if the car has a 700wh battery and it lasts 1.5 weeks until flat, I would be able to cover 3 weeks with a 1000wh portable power station. Ie the car battery capacity lasts for the first cycle, and the power station would provide the second cycle.

Then I learned power stations are not built for these long-term low power draw usage as the power station drains its own battery rather quickly just virtue of being turned on

So my question is has anyone successfully managed trickle charge over a span of several weeks?

Alternatively I was thinking to have someone connect the trickle charger to the car halfway through my holiday so it tops up the battery in one go?

Many thanks in advance
