Lithium Battery

[Slipperyeel]

So what's the standard weight of oem ?. Lithium is 1.1kg. I thought the saving was more than 2kg. Please correct me if I am wrong

In my TC, the OEM was 4kg. Lithium 1.1kg as you describe.

I have to say also, there is a noticeable difference in the starter behaviour with the lithium battery as well. In fact that would be a worthy reason alone to get one, the right saving just adds a good bonus.

There’s nothing wrong with a lithium battery. And a lot right. Lighter better cranking will hold charge much longer and no you don’t need a special charger. Just a ordinary old fashioned 12 volt will do. No smart recovery types as they can fry the lithium battery. Think about it. What makes the charging system on the bike special when you fit a lithium battery? JJH

On one hand, a smart-charger with a built in conditioner should be avoided, as the conditioning means injecting high voltage into the battery.

But an 'Old fashioned' charger may be a box containing a transformer and a rectifier only, and should also be avoided, as these charger may inject too high voltage as well.

If yo buy a OEM Lithium battery, the battery will probably contain built in electronics, BMS (BatteryMonitoringSystem), and the BMS will protect the cells from high voltage.
But if you buy just a battery of proper size, you have to make sure you get one with the built in BMS. This is important, as there are batteries out there that do not have the BMS built in. These batteries may be used in vehicles without a built in generator (such as a toy car for kids), and these batteries are charged with a special type of charger.

If a battery without BMS is installed in a vehicle with a generator, there is no control on the charge current and voltage (taken care of by the built in BMS), and the battery may in worst case catch fire.

Replacing the regular battery with a Lithium battery may be successfull, but it requires the buyer to do his/her homework

Agree
I’d avoid cheapo aftermarket lithium batteries from unknown sources - it won’t save you money if it catches fire, or simply stops working and kills your alternator.

A lithium does not lose its charge over time in the same way as a chemical battery does. IN the blog post linked above, dating back to 2016, that lithium was fitted to my Ducati 848. I sold the 848 in 2018 and bought a new Ducati Supersport, the lithium was put on a shelf in the garage for a year till the Supersport was a year old and then fitted to that bike. It was not charged or maintained in any way but started the Supersport first time. It is still in the Supersport and still as good as it was when new. Never had a charger on it and it has never let me down. It will go onto one of the BMWs when I sell the Supersport.

Wow. That's amazing.

Like many of us, my bike has had to stand for weeks on end with no use or even being started over this last 18 months. Always had this niggle it might not want to fire up. On the contrary. It starts like its new, every time. It's never had a charger on it either - I don't go in for that, don't understand why is needed - unless it's left to stand for weeks AND has a lead acid battery!

Would this work. It has a lithium option (NOCO GENIUS1UK 6V/12V 1-Amp Fully Automatic Smart Battery Charger)

Do you need a charger? JJH

Lithium batteries are 'chemical' just like lead-acid - just a different chemistry.
They do lose charge over time (about 1% per month) - just a lot slower than lead-acid (about 5%).

I know that, just did not want to write whole essay on the subject. Not sure where you get your percentages from.

would like to think not
