There are increasing numbers of motorbike batteries using Li ion that are really light. There is one on eBay right now which is 775g. Versus about 8kg for a Banner. This is serious weight loss. What is the advice here if any of you have experience please?
There's a lot on this in the archives. My summary:
I'd be prepared to fit one, but don't think they're worth it... yet. I'd be very wary of one that didn't have known provenance and previous reports.

Thanks JK. Some of these batteries are in the price range of £75-£100. I’d say that’s amazing price for a considerable weight loss. More and more seem to be flooding into the market. Feedback I’ve had for cold starts is to prewarm by turning on your headlights for a bunch of seconds first. I’d also want a slick bracket/clamp for it.

What do people make of this product:

I couldn’t see any technical data for the battery. Jonathan, could you advise on what Ah battery one would need for a 2.0l Duratec fitted with a isolator/battery master switch? Occasional weekend/dry weather use, currently stored in the garage over the winter and fired up for a short run up to temp about once a month.
Kind regards,

I don't have a good answer, but let's see if we can creep up on that.
But first the warnings:

* Some conditioning chargers now claim to be optimised for lithium batteries, but I don't know how much this matters.
Thanks for looking into this Jonathan... My car currently has a Banner battery fitted, although I can’t get you the current spec as I’m out of the country at present but will be able to look soon. The car is a 2009 R500 Duratec however I’m not the first owner, I purchased it in September 2017 from Caterham as an approved used Seven.
If there are any recommended batteries for a reasonable price I’d consider swapping to something lighter in mass, just so long as it is a suitable spec and can be securely held in place.

I'm really pleased with my Skyrich 15Ah Lithium battery, which only cost £150 ish from memory. Mind you, with no immobiliser on my trusty XFlow I don't have a problem leaving it for weeks anyway. An isolator switch might be good on a more modern car, but the weight saving per £ is unbeatable.
Current Banner is 35Ahr

This was £138 when I bought mine
High compression Duratec is no problem for it
The Magneti Marelli MM-ION-15 is rated at 32 Ah and 540 A cranking.
The Varley Lithium Li5 is rated at 5.5 Ah and 335 A cranking.
Skyrich YT9B-BS / HJT9B-FP-S: 15 Ah, 190A.
JMT Lithium Ion Battery HJTX20H-FP: 7 Ah, 420 A.
The storage capacity on the Varley and Skyrich look low. Any experiences in practice, please, with details of how the 7 is kept, see post #6? (Thanks, Oliver.)
