Jump Starting an MG4 SR

[JonEV]

Hopefully someone a little smarter than myself knows the answer to this.

I have the 12V drain issue which I should be resolved by a quick software update.
However, until my local MG garage find the time to fit me in, am I okay to jump the 12V system using jump leads and a nearby ICE car (with the owners permission of course).
I see a lot of talk about boosters and assume they will perform the same function, just wanted to check.

It is ok to jumpstart the MG4 from another car, but what must never happen is the other way to other car than an EV.
In other words, never jumpstart an ICE car from an EV as the EV startbattery is to smal and you risk to kill your EVs battery charger (very very expensive). I think this is highlited somewhere in the manual.

The jumpstart procedure is found in page 263-264 in the manual.

P.s. No need to have the ICE car running when jumpstarting an ev and be sure to remove the jumpstarting cables as son the MG4 is in ready state.

Thank you, I was searching the manual but couldn't see anything.

You can also get batteries - both lead-acid and lithium ion - with jump leads attached which will do the job without needing to go cap in hand to an ICE car owner. Many people keep a lithium ion one (small and quite light) in the car just in case.

A lithium battery jump pack to power up a lead acid battery to power up a lithium traction battery… what do you need as a back up to the jump pack?

You can also get rechargeable jump starters on Amazon for around £50 - £100 and keep it handy in the car. Just remember to charge it up occasionally.

The 12v socket of the car. It’s like having two buckets with holes in them.
