I was so happy that the excite 51 came with an LFP battery! I probably wouldn’t have bought it otherwise and would still be waiting for an EV I was happy with for under 40K
Excite 51 I have is also a really nicely damped and handles much better due to the lowest weight in my opinion of all the MG4 variants.... so good I bought one new in volcano metallic orange!
Thanks Jerry for all your time and effort you have put into these "how to" videos on the MG4. They have been most helpful for me to understand the "bells & whistles" that the MG4 has. I've owned my Essence 64 since mid November 2022 and enjoying the EV/New car experience. I especially enjoy the regen when slowing or stopping.
In the MG4 user manual the manufacturer recommends same: if you leave the vehicle for a long period, make sure battery has at least 50% charge remaining.
I live on a mountain with a MG4-51 and I've found it's best to charge it to about 95% so that the regen braking is effective on the way down the mountain, this extends the life of your brakes and I regen to about 97% by the bottom
@@philipepics I drive down the mountain 3 or 4 times a week and if I use physical brakes (charged at 100%) I lose ~2% of my battery (as well as wear the brake pads), but if I start at 95% I gain ~2% and minimise wear. Here's a video explaining regen; ua-cam.com/video/88K5aoRYBgg/v-deo.html
Really excellent information. We are just about to purchase a new MG Long Range 77. We live out on a farm so our minimum return drive is not less than 20klm. It will not be driven daily but if we go into the city, it’s a 300klm round trip, not counting any side trips. Thanks for your advice.
Have had an MG4 from November 2023, and just had the 40k service.. that's 3 trips from Townsville, through Sydney and Melbourne to Adelaide and back in February, and back to Adelaide with no issue on charging, just need to be easy in the 110kph zones.. happy travels..
Thanks for your efforts Jerry. A very useful source of information. I hope MG and your employers appreciate the work. It certainly increased the likelihood of my buying an MG4 and has helped me through the early weeks of ownership.
I watched it again, as an update/refresher and realised I'd missed the monthly 100% AC suggestion, so I'll start doing that. No faults on my 18 month old long range as yet. Lovely car.
Thanks for all your work on these videos, If I had found them before I bought my MG 4 I may well have been tempted to drive to Auckland to Purchase off you, not that I am at all dissatisfied with the guys I did get mine from, just that this is such an effort it deserves rewarding. :)
Love your work Jerry! I watched all of your videos on the MG4 excite 51 before it was delivered. It helped ma a lot. Thanks for this update on charging the battery. Keep up the good work!
thanks for doing these videos Jerry, I bought a second hand MG4 just the other day and your content has been a fantastic source of information - I had no idea how to even charge it before :D
Hey Jerry I am from Indonesia and planning to get this car. All your tutorials are excellent and concise and appreciate that you make them. Wish i could buy this car from you 😂
Re 9:12 and a long term test of the HV battery when the car is parked for an extended period, one of the MG4 Owners Australia FB members parked their MG4 [Excite64] at the airport for 6 weeks. They reported 12% consumption on the HV battery over that time.
is this because of battery active cooling or heating? I'm from the Philippines. I'm worried that our hot climate here could degrade the battery faster.
As a qualified Chemist (BapsC) you cannot ignore the advantages of LFP batteries over the older generation of Lithium Ion. In terms of just use, your getting at lease 3 times more cycles for the same degradation and full use of the battery size in LFP... in simple terms 10,000 charge cycles from 10-90% for Lithium Iron vs 30,000 Cycles for LFP at 1-100%... Also LFP will not catch fire and overheat. Often the Slower Charging of LFP batteries is due to the internal car transformer being smaller as LFP batteries tend to be in the less premium models. Why Car manufacturers dont use them in all cars is that the size of the battery gets too big to fit easily into the car at around 64Kw for the LFP battery, as it has about half the energy density and volume. I own a model Y Rear wheel drive and a MG4 51 Excite, both LFP and the Y gets 435 Km range ( and has lost 7km of range after 40,000 km!) and the MG4 51 Excite gets 350Km of Range (new so no comments on range loss).... I dont think I would buy a non LFP battery car at the moment unless it was a bargain second hand.
@@clayton4115 sure I checked your battery type its the older generation Lithium battery but its a good battery with a history of good performance... This battery should not be charged over 90% unless you are going to use the car straight away and deplete it below 90% (they get damaged if held at over 90%)... if your daily usage between charges allows it I would even only charge it to 80% for a typical work day. I see some youtube videos showing 10% loss in range is typical per 40-50,000 Km... Thats a good result for that older type battery.... have a nice day.
Hi Jerry, Is there a menu (hidden) or otherwise (OBDII?) method to check if there is any imbalance in the cells for example? I feel like I drive very little yet the MG4 (NMC) seems to be losing % a lot.. Ex: I'll drive ~2km and I'll see 1% drop. That's in normal just with AC without any sort of acceleration..I'm very aware of the %power use and generally outside of starting from a stop it sits between 0-10%
Hi Jerry, thanks again for the great summary. Regarding #4, the manual mentioning a feature "intelligent charging". It states the 12V battery charge is maintained by the HV battery "under certain conditions". is there any other condition needs to be filled apart from the few which is listed in the manual (page 23)?
Jerry, I left my Excite at the airport for 6 weeks and had a main battery charge loss of about 12%. Still had 50+% left to drive 60km home with absolutely no issues. Was the charge drop due to maintaining the 12v battery?
Hi Jerry I watch your channel in Thailand. We have the model X mg 4 ev here in Thailand. It has a 51 kWh battery. Please kindly confirm that I can use the public charging station at the dealership to charge the battery to 80 % every time. Because I live in an apartment complex and don't have a home charger installed. So I can't alternate charge monthly using the home charger. It has to be public fast charging to 80% all the time. Thanks 🙏
@@JerryPanandCars Thanks for your response. I remember that in your video you mentioned that there are 2 types of batteries. The 51 kWh battery is ok for charging UpTo 80 and more. But the higher capacity long range battery charge preference is 80. So to summarize the 51 kWh battery and the higher capacity long range battery both need to be alternated with home charging once in a while. But the 51 kWh battery can be charged UpTo 80 and more all the time.
I bought the lfp one because I want to drive it as long as possible. Do you think it could last 20 years or something like that with 15k kilometers a year?
Hi, Jerry When you turn on Air-condition MG4, you can hear very loud annoying noise anyone agree with me? (you have to hear it from outside of the car) Can you discuss this matter with your MG engineer please? this is very frustrationg..I think every MG4 does make same sounds It will be a recall matter I guess, Please advice me
One way, disconnect the 12v battery under the bonnet. Search it online. 2nd way, get some to start the car after 2 months or so to drive it or charge the 12v battery.
Try this and see what happens: get the battery to 80%. Set the charging cut off to 90% and start charging again. Set a timer for 1 hour or however long it takes to go from 80 to 82%. Must be 82% or more. When the battery is at 82%, while charging, change the cut off back to 80%. If the battery needs to balance it will start a cell balance and remain at 82%. This could take an entire night on AC mains. I found this feature by accident. It’s not documented anywhere. This is how I ended up listening to this channel. I found this especially useful after a day of multiple DC rapid charging. For me, the MG4 has way too many of these undocumented features. Edited March 2024
I've jst finished watching an MG4 Xpower video from the UK. They mentioned a 77Kwh battery version for the Xpower. How long before that bigger battery is available in NZ and Australia? Assuming we'd be on the same timetable.

2:27 zero thermal runaway? You sure? If I short a series of 6 LFP batteries of size 14500 one of them will burn until the electricity is gone from all of them. The main difference is that the LFP battery gives off CO CO2 and H2 when or if it gets hot enough to burn. It doesn’t evolve oxygen or Cobalt soot. This could happen if the whole car was put in a furnace or a house fire. The electrolyte is still Lithium hexa fluoro phosphate. I would have preferred an LFP MG4 but didn’t like the option list

Wrong, the standard MG4 51kwh LFP version loses 0.01% every day when using the car or not in a scheduled manner. Perhaps this information from the SOH is factif? In 11 months and 22,000km my SOH is 94%! Can you confirm to me if this information of programmed degradation of 0.01%/day is factual or real please?
Not exactly on a timer. The MG software is rubbish where it can't calculate its own health. I have the LFP ZS ev. 51kWh If you dont do a deep discharge once in a while that SOH will drop. Also, the Gom will drop as well. The lowest I went on my 13 month old LFP ZS EV was 13%. Then SOH increased from 95.5 to 97.5% right away. While other factors do affect health, doing frequent low discharge and then charging to 100% on the slow AC charger does help.
@@theelectricmile474 I even did voluntary discharges with the heating down to 0% so that the SOH went back up without success. This car has several faults, and I'm almost sure the battery has a fault too.
Hi Jerry, Great video again. There is a lot of scaremongering from EV haters online. I saw an invoice which I am sure was fake for a replacement batter costing $39,000 for an MG4. Just to set the record straight, what is thr approx cost to replace an 51kWh battery?
I'm not sure about the cost honestly. All I can say is, it isn't going to be cheap. But, the price of replacement battery is honestly irrelevant for most EV cars and EV owners. We have had 4 years' experience with MG EVs from gen 1 MG ZS EV to MG4 and I have never heard any of them needed a battery replacement. It is like buying a petrol car and asking how much it will cost to rebuild this engine and chassis. The answer will be similar but honestly irrelevant. No one expects them to fail in any short time frame.

If you charge to 80% most of the time, there would be hardly any range loss even in long run. Buy an slow charger and enjoy
For the 51 excite how do you check the battery health (degradation status) and what is the best practice to prolong its health?
Battery health can only be checked at dealership
Hi Jerry, could you do a video on how to disconnect a 12V battery on MG4 please . There no video online for that
It is the same like most cars on the market.
Would u be doing a review on the 12volt battery? How to protect or charge it etc? Cheers

Never used one :(
So, what I understand is we need to charge 100% once a month, even the car is NMC 64kwh long range version?
That's what I found from some recommendations only (not MG official). Charge to 100% around once in a month will help.
Try this and see what happens: get the battery to 80%. Set the charging cut off to 90% and start charging again. Set a timer for 1 hour or however long it takes to go from 80 to 82%. Must be 82% or more.
When the battery is at 82%, while charging, change the cut off back to 80%.
If the battery needs to balance it will start a cell balance and remain at 82%. This could take an entire night on AC mains.
