Yebbut what's already in em? Can't be a Bosch shurely?Try a Bosch S4002 battery (12V, 52Ah, 470A), or a lithium ion.

I don't have my MG yet, but if it's anything like the Kona they put a cheap 12Ah battery in. For longevity, you want something with double or more the capacity to prevent bricking the car when a light is left on or something similar.Yebbut what's already in em? Can't be a Bosch shurely?
These items you mention will draw a massive amount of power when booting up the car, that will drain a jump pack pretty quickly for sure.Depends on what the car does when you turn it on.
If it fires up the front headlamps, cabin blower motor, and possibly even the AC pump, they can draw a pretty good amount of current
But honestly, there have been so many problems with the original battery packs i think, that it would never hurt to just get a new battery, charge it up, with a charger, and plonk it into the car.
I know it will cost a bit, but it would also help a lot with the burden of having the car break down all the time
I have not had any problems with the battery in my 2022 LR, but i can tell you for sure, that at the first sign of problems, the battery is the first thing i am going to replace, for something i know is "quality".
I have started this thread because I have seen so many comments about how crappy the 12v battery is so I am looking into viable upgrades ranging from bigger lead acid batteries to Li-Fe or Li-Ion to save a bit of weight in the process. We can also use this thread to discuss options on how to keep the 12v battery in tip top condition whether that be a smart trickle charger if the car isn't going to be used for a while etc.
You probably better off with a AGM or just a Premium battery the 096 batterys are the next size up from standard and fit the 2nd hole on the trayI like the idea of a LiFePO4, but would it charge correctly?
Just out if interest have you tried pushing and holding the start button it could Force a reboot?Well, it wasn't the battery .
Tested the 12V, and it was a bit low, but nothing horrendous. Popped some jump leads on it, checked again, it was getting a solid 13+V and...nothing. I even tried hooking it back up to the HV charger, and it refused to connect.
HV battery is still disconnected, and still showing the same VCS fault as before.
Big yellow taxi time again tomorrow, Arnold Clark can deal with it. A few of my mates have already said I should demand a replacement or refund...I'm starting to think they may be right
Sorry to hear that the problem had not been resolved.Well, it wasn't the battery .

An AGM would be the obvious choice, but a LiFePO4 would easily cope with current demands, would be faster at charging, would last much longer at a higher voltage (which would eliminate issues caused by low 12V)..... I can only think of advantages - except of cause price (although not much more from our supplier) and possibly charging to full capacity (depending on float voltage from charger) - surely worth considering?You probably better off with a AGM or just a Premium battery the 096 batterys are the next size up from standard and fit the 2nd hole on the tray
Don't EVs have DC to DC convertors rather than alternators as have no engine to run an alternator off?A quick Google search I probably would not try it View attachment 8964
Yes but I would imagine that the bms set up for normal batterys that's why it is supplied with one?Don't EVs have DC to DC convertors rather than alternators as have no engine to run an alternator off?
When this happened to me last week the AA held the Start button for about 15 seconds the car shut down - he waited a short while and the car rebooted with everything working
Where's that quote come from then?So my holding down start button idea may just work some sort of reboot
Ah found it on the other threadWhere's that quote come from then?
