batteries
A battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices. When a battery is supplying power, its positive terminal is the cathode and its negative terminal is the anode. The terminal marked negative is the source of electrons that will flow through an external electric circuit to the positive terminal. When a battery is connected to an external electric load, a redox reaction converts high-energy reactants to lower-energy products, and the free-energy difference is delivered to the external circuit as electrical energy. Historically the term "battery" specifically referred to a device composed of multiple cells; however, the usage has evolved to include devices composed of a single cell.Primary (single-use or "disposable") batteries are used once and discarded, as the electrode materials are irreversibly changed during discharge; a common example is the alkaline battery used for flashlights and a multitude of portable electronic devices. Secondary (rechargeable) batteries can be discharged and recharged multiple times using an applied electric current; the original composition of the electrodes can be restored by reverse current. Examples include the lead–acid batteries used in vehicles and lithium-ion batteries used for portable electronics such as laptops and mobile phones.
Batteries come in many shapes and sizes, from miniature cells used to power hearing aids and wristwatches to, at the largest extreme, huge battery banks the size of rooms that provide standby or emergency power for telephone exchanges and computer data centers. Batteries have much lower specific energy (energy per unit mass) than common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting electrical energy to mechanical work, compared to combustion engines.
Has any one had experience with either of these home storage batteries. I've got an installer lined up and I'm between 3 givenergy 9.5's with 3 of the 3 kW AC coupled inverters or 7 Fox ESS 4800 batteries (1 master & 6 slaves) with the fox kh10 hybrid inverter. Interested in any...
I am looking at possibly taking out a service plan and note on the MG website that they suggest different levels of service based on annual milage. EG below 10K per year, and 15K per year.
On the higher milage plan the key batteries are shown as included 2nd and 4th years, but on the lower...
Hi everyone in the MGEVs podcast on Monday 4th March there was once again a fair amount of discussion about charging your EV well the 2 videos below I think give a very clear explanation of what is considered best practice for different types of batteries in the first one.
And the 2nd one...
The information in these to videos could be helpful to those new to EVs and those not to sure what they should or shouldn’t be doing with the cars have a watch.

This is the first EV with removable batteries
How long before battery tech will get so advanced that batteries become small and light enough to put in your bag?
I have been paying our old electric company £365 per month for charging the MGZS EV and running a pond pump.
I have now had 12 solar panels and two 5kw batteries installed and that has knocked 75% off the cost of our electric its a big investment but at this rate 3 years will provide pay back...
Greetings MG EV Community,
I wanted to take a moment to share our recent journey of enhancing our EV experience by installing a myenergi Zappi car charger and a 20kWh Libbi battery storage system.
Our setup already included solar panels that reliably generate a sturdy 4kW, but we wanted to...
Maximising Battery Life for High Nickel Batteries by Jeff Dahn! This synopsis taken from the Limiting Factor.
Jeff Dahn is one of the fathers of the Lithium Ion battery, along with John Goodenough, Stan Whittingham, and Akira Yoshino.

Hi all this might be of interest,
Batteries and the state when car was left standing for 15 days
At the start
And after 15 days standing
You may well notice the 12v is showing 0.2 lower was due to me leaving the car switched on for around 10 minutes while I went indoors to get my phone to...
So in Wiltshire this week the sun has been shining and I have been reaping the rewards of the improved weather.
I am currently sat at 49% battery with a range of 123 miles (ECO) which is great to see, so if I ran this battery from 100 to 0 I could hit 250.
Mixture of town, country and A roads...
