I use an Odyessy PC680. Only 20 turning cycles so if you leave your car with an alarm on it will go flat within a few days.

30 AH lithium Ion battery are starting ( Confused

) lowering price, but still expensive:

http://www.skyrichbattery.com/Lithium-Ion-Battery/c10/p552/HJTX30L-FP%3Cbr-/%3ELithium-Ion-Battery-YIX30L/product_info.html

On ebay you find this 30 Ah model (it weight only 2kg!) or similar at about 200 euro:

Something less (150e) if you search for the 20Ah model but
not sure it is reliable for a 1700cc motor (maybe ok only for racing)
but in the application list there is also honda 1800cc Gold Wing motorbike:

Oh and I forgot to mention, if you are putting the battery on its side then it needs to be a sealed unit, I have done this to keep the centre of gravity as low as possible. I wass going to put it in the boot area but couldn't be arsed.

I use the same as Iain.

Mine is on it side. It is a Redtop and pretty much what Iain shows in the ebay link.

Whenever I need one I tend to look out for a decent secondhand one on ebay. They have always seemed to have done the trick - not had a dud yet!

Plan will be to keep the lightweight battery on a ctek charger whilst not being used and when on track the normal battery will be used to jump if necessary.

I've been down this rabbit hole before â€” the Odyssey Extreme Racing 20 is a solid choice for lightweight applications, but I'd steer clear of budget SLA batteries if you're putting them in anything that sees regular use or vibration. The Rapid one you linked looks like a generic sealed lead-acid, which might be fine for a backup or low-draw setup, but don't expect it to hold up to repeated deep discharges or under-bonnet heat. If you're looking for more gear comparisons or performance reviews, desi casino has some other useful content worth checking out.
