(There's also some numbers from James on the effects on lithium batteries in EVs.)

Thanks Jonathan that's what I hoped but didn't want to risk it after investing recently in new battery and ECU!

Its a Motocell Lithium Gold (sold locally under that brand but probably available in UK under something else?)

I can't imagine a battery in the engine bay would remain at below 0 degrees for very long, and if it's just started the car that's probably enough to raise the temperature to a safe level to receive charge from the alternator.

Unless you're in the arctic circle at < -40 deg C. In which case a Li-Ion battery might not be the best choice. Or, indeed, a Caterham.

Aghhh update I fitted a motocell lithium gold to my k series 4 months ago.... advised by shop that 6ah would do it but " no warranty as your putting a motorcycle battery on a car"...what could possibly go wrong? Soooo

4 months 3 accident full discharges & 100kms of an alternator hanging off and dead....

trying a lithiumax 520 cca now warranted for 2 years but $600... will also check alternator when fitting to ensure a1....
