The numbers.....

Leisure 12 x 2 x 110 / 2 = 1320Wh

Bikes 2 x 36 x 8 = 576Wh

So you take about half of your stored electricity. Can you cope with other half and can you recharge the hab batteries in time for next use.

Am I correct in thinking that you are only supposed to let lead acid batteries drain by 50% so in the calculations, if the bike batteries were 'empty' then they would require the full usable charge from the battery ?

Yes.

No. I put / 2 in the calculation. The rated Wh of his batteries is 2648Wh.

The big question goes unanswered, how to replace all that electricity. In Spain if has solar panels he could manage it a lot of the time.

With all these questions the best answer is suck it and see.

Thanks for all your comments at the moment we have 1 x 100w solar panel but I am thinking of putting another 100w panel and adding another battery
