hi

 

Sorry if this topic has been covered before but was just after some advice on a smaller lighter battery at a reasonable price?

 

My car lives in the garage during the winter on charge so dont need a heavy duty battery, more interested in saving some weight with a smaller lighter one.

 

Has anyone got any suggestions?

 

many thanks

Ben

I fitted a Shorai LFX21A6-BS12 on my elise. 1.35kg vs 11.5

 

~£150.

 

Saving weight in the front of the car not considered the best place mind.

thanks for that 10kilos is a good chunk of weight!!! :-)

In the wrong place though.

But why do the Exige and Elise run the battery in the rear if there's a big problem in losing the weight in the front?

Aircon

Some move it to the front.

If you're using a lighter exhaust (standard isn't the lightest thing in the world!) and perhaps switched away from the standard airbox to something like an ITG etc. you could have saved ~10kg from the rear, in so helping retain some of the front / rear "wedge"..

 

I don't think that battery would last long in my car mind you!

So an extra £100 to save 10kg of weight that you wouldn't be able to notice! Makes perfect sense to me😄😄😄

How far do you go with that logic though?

 

When is it worth trying to save weight in the car?

 

I expect £10/kg is high up on the value scale if you were to compare other options.

IMO rarely, (but that's just me!) unless it's a race or track only car and part of an overall 100kg - 150kg target. & as Fez says, in the right places Each to their own though I can never get out of my head the guy at Snetterton last year in a Loti who was preaching about his weight saving ideas. He must have weighed in excess of 18 stone

I agree with you Paul, no point if you ain't racing.

[DanGT]

Does that mean if you are tall and have the seat further back then the weight distribution will be wrong? :-p

[Paulus H]

Just be careful with some of these race-batts. Some are just smaller. they are the same weight but the dimmensions shrink dramatically. I guess the idea is that you can fit them low down in otherwise inaccesable areas of the car. Kindly, Paul
