Lithium Ion battery.

Hi, I have a Shorai LFX36A3 on my Elise. Seems to have failed. Looking for a replacement lightweight battery.  A Shorai is £350 plus specialist shipping!

Odyssey PC 625 smaller than the popular PC 680 and better cranking ability.

If you do a search on here there was a thread on batteries about 3 years ago i think, and I'm sure Martin R found a lithium ion one for about £150?

Hi. Guess it depends on what you are aiming to do by having a lithium battery ? If you are on an OCD weight reduction process it’s worthwhile . If you just fancy one cause they give a bit more boot space and look cool then I would be mindful . I ran an odyssey for 3 years similar to Martin and tbh found it a bit of a pain. Didn’t hold its charge very long at all , so if you don’t use the car every 3/4 days you will need to remember to put it on trickle as part of your parking up routine . Mine eventually went pop ....literally after it failed to re charge from flat so I replaced with the lightest weight standard battery and don’t notice any difference at all . 
All just my opinion of course, but that money but towards new suspension , engine mounts, tyres, cam change, etc all where money better spent

Thanks for that, I had a lithium too, great, very light but a pain to keep charged. I gone for an Odyssey PC625 lightweight replacement.

I have had an Odyssey PC680 for about 4 years now and I have been happy with it.  It saved about 5 or 6 kilos in weight from high up at the very back of the car - the absolute best place to save it from in a car that is already a lot heavier at the back.  Having said that, while I can feel the difference on track, in all honesty I can't on the road.

Another advantage is more boot space, especially as mine is mounted lying down (lower c og g too!).

I found if the car wasn't used regularly i needed to put the charger on every three weeks - nothing fancy, just a standard Halfords charger. I would charge it up overnight and that would do it. No real hardship as I have a door into the garage from my kitchen (It was why I bought the house 😁).  The cranking power is way better than a standard battery.

Unfortunately i got lazy this last winter and forgot to charge it. It went completely flat a couple of times and now doesn't hold charge and needs replacing.  My fault I think, not that of the battery.  I will get another from Demon Tweeks unless someone knows of anywhere cheaper.

I've got my PC625 fitted, not as light as the  Shorai Lithium Ion but much better value😁

PC625 has been good for me on the Exige with a cut off on the battery I’ve had no need for a trickle charger 👍🏻
