Stock Battery

I’m about to get a G80 (stick shift G80 on order, stuck in port for a while).

In my business we’ve switched all of our robots from AGM chemistry to LFP and LIION batteries, and the performance in terms of weight, longevity, and performance in low temperatures is huge.

Assume the stock G80 M3 battery is an AGM? Has anyone switched to something better (i.e. a lighter LFP or LIION)?

No, G8x cars come with lithium starter batteries. Huge money to replace too.

Any idea on specs? Guessing the stuff mentioned here https://g80.bimmerpost.com/forums/sh....php?t=1807274 (70 ah LIION) is right?

From what I have seen it is 860 CCA, 924Wh not sure of group size, weight etc.
They list for around $1,900 but I think can be bought for about $1,500 +/- USD.
