64kwh Xpower battery different to stock MG4 ?

Ive been wondering about the battery chemistry of the Xpower. I am not sure MG would slap a 7 year cover on the battery from the standard 64 MG. Pulling double the amps ! has anyone any detail on the battery ?

I'd be surprised if the 64kWh battery pack was different in the XPower ... I reckon the pack is easily capable of coping with the XPower load (remembering that it is peak power that is drawn, not constant power - the car will throttle back power if the battery temperature rises too much), and that in the LR models it is not being taxed.

As above ... I don't think the Xpower managed a lap of the Nürburgring without losing power. It's great in short bursts for normal driving though.

Only thing that does seem strange is the extra 0.1 kWh on the MG website as the XPower shows as 61.8 kWh usable compared to the 61.7 kWh of the LR

It is the same pack and same cooling system. Unfortunately they did not uprate the cooling, which you'd need for track work. But then few people ever go to a track, so it does make some sense.

Building a battery to support 320kw or building a battery for 150kw , its not just heat, higher performance batteries cost. Id say same shell and cooling, bigger copper busbars, bigger fuse, bigger relays - and possibly different cathode and annode materials to support the small amount of xpower MG4s. Or MG are taking a gamble on how they abuse the cells.
