If you are considering a lithium battery, bear in mind it does have pros and cons so it may not be suitable for all situations. Glad to explain if you guys want to know why.

This isnt a battery issue man...this is a user issue...if u know ur bike is unused for 2 weeks or more u should really remove the terminals from the battery. Any battery u use will drain with that kinda non usage.

There are systems in ur bike that still requires some low amounts of power when the bike is off...like ur clock..internal memory for ur settings, mileage etc..

This is same for any vehicle...starting the bike/car at least once a week for 5-10 mins is more than enough to keep the battery alive. Also helps to keep ur internals lubricated.

1 more thing.. if u plan to buy Yuasa YTZ battery, plz open the box & chk the DOM. Some shops has "over idling" (>8 mth) stock which can lead to shorter usage life span.

Motorcycle Lithium batteries are built with BMS that is specifically designed with a bike  charging system. That said, here are the pros and cons.



Cons
Equivalent Lithiums typically only have 1/2 the reserve capacity of same "sized" AGM. This is because lithium battery manufacturers follow the CCA of regular AGM to "size" the battery. My new lithium ytx14zt is 76whr, while the factory AGM is at 144whr. So read the specs carefully.
Not good in cold weather (does not apply to us, see below)
Can explode and catch fire spontaneously (hehehehehe.... especially charged when very cold) Lithiums need a short warm up to wake up (by turning on ACC and lights) before operating below freezing temperature.

maybe install a battery cut off switch at a more convenient location. the constant draining of the battery like that and recharging it can also reduce lifespan significantly

so its user problem . hahahahahahahahaha
I would do what madmen suggests. Install an inline cut off switch. But then again you will loose the alarm.

FWIW, dont charge a big phone or anything big, without the bike running. a big device like my 13200mah phone can drain a moto battery real quick.

Is this connected directly to the battery (not switched off when the bike is off)?

thanks

I copied the link to show the wiring diagram, and did not check it was the correct link
there's a module, and uses ACC power to switch between modes, so it protects the battery

Just an update on my Dynavolt LFP battery. Started to see some voltage drop on start up. Still cranks good. Let's see how much longer this lasts. It's been like what? Only 6 months?

The NK seems to eat battery. No one can get batteries to last over 2 years. Too much active always on electronics I think.
