BALLISTIC EVO2 16-CELL Battery

[acafrao]

Looking for one of this wonder batteries.. So if anyone have anyone spare or to sell or know any good place to get one please let me know.

 

Also, if anyone has any experiences with this battery please let me know.

The battery is roughly 6.x amp hours (20 amp hour lead acid equivalent) It can start the car short term just fine, but the cells are being overtaxed-- the discharge rate (coupled with AH) isn't enough for an engine bigger than around 1.2 liters. Thats why the battery is so light-- the cells arent dense at all. The cells will get damaged after a short time and quickly become inefficient.

In our tests using a comparable battery (when we were first trying to see how many AH, etc we needed and how light we could make the battery), it lasted about three months of "semi-daily" use on the Exige S.

It all comes down to what you use it for-- if you are looking to get every ounce off your car for a race season, it may make sense to get one or two a season and consider them disposables.

Ps- Judging from their warranty... They seem to agree with me

Their "3 year" warranty:

1-6 Months — Free Replacement
7-12 Months — 75% discount from retail
13-24 Months — 50% discount from retail
24-36 Months — 25% discount from retail

 

 

All found on the Lotus Talk forum... 

 

Not sure I'd want to spend £360 on a battery either.    .. http://www.ebay.co.uk/itm/Ballistic-EVO2-16Cell-Compact-Lithium-Ion-Battery-Race-Competition-Cars-1-6Kg-/230877558728?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item35c15ff7c8

 

you could buy an awful lot of Odyssey PC625 batteries for that

So the best lightest battery uouwould recommend is tht odyssey?

What about this one http://www.ebay.co.uk/itm/Lithium-Ion-12V-Motorcycle-Battery-Race-Car-Kitcar-Lightweight-Replaces-YTX14-BS-/221198701508?pt=UK_Motorcycle_Parts&hash=item33807853c4

Nobody has lithium batteries fitted??

[peterg]

I guess people who want the ultimate lightest battery (and have lots of money) might try the Ballistic ones but most of us less well-heeled amateurs compromise and fit Odyssey PC625 or PC680 (also sold under the name Powervamp)* which save a lot of weight over conventional wet cell batteries and can be fitted in any position without cost more than £100

 

*Varley Redtop batteries are widely used and comparable to these but usually cost a bit more

I don't think there are many Westfield owners running them, there are probably more, but the only one I can remember is JohnCH who doesn't come on the Boardroom so often. He did seen pleased with his, though I don't recall what brand etc. I think they've been a little more common over on the Darkside - I recall a few threads about them on Blatchat.

like everything, it's a co promise, it's just the Lithium Ion batteries are a different set of compromises.

The other thing that springs to mind though, is everything else on the car as light as it can possibly be? (And do you need it to be?)

[Terry Everall]

Several people in the speed series run Lithium Ion batteries( weight 1kg) and they seem ok

Cost is about £145

YTX14 is the one to get

Terry the YTX14 i found are about 40quid. I am sure it is not right. Also would this crank my zetec 1800?? Thanks

[Terry Everall]

the Yuasa YTX 14 is a gel battery and very good for the monet

Would probably crank Zetec ok

The YTX Lithium Ion is the lightweight expensive one

One of the traders on Locostbuilders sells them here they are quite reasonably priced and he seems like a nice chap.
