Lithium Batteries
Hi Guys,
Just wondering if anyone here runs a Lithium battery, looking at getting one for our next race car.
The one i am looking at weighs 1.5kg, so over 6kg saving over the required odyssey.
However more interested to see if anyone has had any problems and what battery have others used? CEC or BEC.
Seems a no brainer in terms of weight but need to be certain it wont let us down.
Thanks in advance.

An expensive way of saving 6kg!
Will 6Kg make that much difference in perofrmance?
1. The point of a journey is not to arrive.
2. Never take life seriously. Nobody gets out alive anyway.
Best Regards

Well, its £100 more than a oddssey so 6kg for £100 is pretty reasonable in racing terms, and yep a couple of 6kgs all add up. This is on an out and
out race car.

Dave Watson tried one in his RGB car Eddie. And threw it away.
I think it wasn't beefy enough, a bike ECU really needs its voltage and ISTR this was dropping quite a lot when cranking.
Not very Locost but very BEC

I have absolute confidence in the Li Ion Polymer batteries I sell. I'm happy to supply on the basis that if it won't do the job you want
it to then return to me (at your expense) in "as new" condition with the original packaging & I will refund in full less my P & P
- that message is not just for Eddie, it goes for anyone on here.
Only qualifier I would put on that is if you're unsure of what you should be using then talk to me first, it's no use taking the smallest,
cheapest battery in the range then asking it to start a Dodge Viper!
Here's the Link again to the video I've done, video is about halfway down the page now
I no longer run Furore Products or Furore Cars Ltd, but would still highly recommend them for Acewell dashes, projector headlights, dominator
headlights, indicators, mirrors etc, best prices in the UK! Take a look at http://www.furoreproducts.co.uk/ or find more parts on Ebay, user names
furoreltd & furoreproducts, discounts available for LCB users.
Don't forget Stainless Steel Braided brake hoses, made to your exact requirements in any of around 16 colours.

Lithium Iron (LiFePO4) surely? Lithium Polymer cells are not suitable for automotive applications.

Yes, sorry I think your nomenclature is correct & mine is wrong - I would point out I'm not a battery expert or a chemist/physicist!
However, I am a great believer in practical tests & "if it works then don't argue with it"!
I have just done some more testing, will post a video as soon as I can get it done, I have just taken the SMALLEST battery in the range the LIP004
which is intended for mopeds, scooters & small capacity motorbikes & used it to start a Furore fitted with a 1.6 4AGE engine, yes,
that's right a battery weighing 430g, a 4.5m long starter lead cos the battery is at the front & the engine at the rear & it not only
turns it over but starts the engine, what's more I disconnected the coil lead & cranked it for around 10 secs, by which time the battery was
obviously struggling, reconnected the coil lead & it started first time.
So whether you're running a bike engine or a V8 or anything in between I reckon I have a battery which will do the job & save you anything
up to around 20kg!
I'm just doing some drain down tests on the smallest of the range to see if I can get some sort of idea of Ah figures.

The LiFePO4 batteries sound awesome. How long will they hold a charge, i.e. can you leave the car a few weeks or months and still start it? Any idea
what sort of long-term life expectancy they have?

Holding charge whilst unused is a LOT better than lead acid, they have very little drain down from being left unused, I've got a couple of (slow
moving!) batteries which I've had in stock since I started doing them about 3 months ago & they still show a full charge when tested.
The other thing re long term drain down is that they will recharge VERY quickly, the manufacturer says 90% full charge in 6 minutes, but personally I
think that is somewhat optimistic, you would need a substantial charger to do it & I would not think good for battery life, but from my own
experience I can confirm that they do recharge VERY quickly indeed, certainly within about 15 - 20 minutes to get a fairly complete charge into
them
Long term life expectancy, you have to remember this is relatively new technology at least in this application - they are guaranteed for 12 months,
they have an expected cycle life of around 2000 charge/discharge cycles, that's compared with lead acid around 200 - 300 charge discharge
cycles. The manufacturer has been selling them without problem for over 2 years, my supplier has been selling them for getting on for a year now &
has not had a single battery returned under warranty, for the longer term the simple answer is that no one actually knows as although you can cycle
them many times in a lab, you can't reproduce the ageing process.

They sound better and better... any idea if they would be OK starting a 3.2L straight 6? Presumably I'd want to be looking at the biggest one
for that application?

From testing I've done so far I would think the LIP014B would be perfectly adequate for the job, but I've got nothing to make a direct
comparison with, I'm certain the LIP020A would do the job no problem.

This confirmation should definately have been added to the previous discussion on these batteries as that also led to the impression they were LI-PO,
not LiFePo4
