991.2 gt3 Lithium battery

Morning all,

There has probably been a thread on this, but struggling with the search....

I was thinking of fitting a Lithium Battery in the Spring due to the large weight saving over the standard AGM battery.

Has anyone on here done the same with a 991 gt3? If so, what make did you fit and did you need to make any changes to the PIWIS?

I was thinking the Antigravity H8 size looks good.

Many thanks,

Mark

Thanks Taffy.

Do you rack your Gt3? Reason I ask is that Antigravity seem to suggest that you should get the PIWIS re-programmed to lower the charge going into the Li battery at consistent high revs

Thanks gents

Any warranty issue?

Mate is saying change will void Porsche warranty, which seems harsh!
