Transporting spare battery - advice welcome!

[timidtom]

Joyce is doing a charity bike ride a week on Sunday. As resident worry-guts I'd like to see that she takes the battery from my bike as spare (it's a women-only ride or else I'd be there alongside her. Of course I would. Who wants to sit for two hours in a coffee & cake shop with only a crossword for company?)
The bikes are Classic JuicyBikes, the batteries are Li-po 36v 10a. I suppose the spare could just be plonked in one of the panniers but there has to be a better way????
Thanks for thoughts,
Tom

I just used the panniers for multi-battery runs, some runs with three batteries, one in use and one in each pannier, all 36 volt 10 Ah.

I once tried to get clever with a spare Lafree battery "securely" bungeed all ways onto the carrier. Flying down a long very bumpy hill, the battery broke loose somehow, hit the deck and overtook me, so it was panniers only from then on.

The case was split nearly all round the top and along one corner seam, but fortunately still working. I used a solderig iron to heat seal the splits and reinforced it with some duct tape:
