Lithium batteries

[duke63]

Anyone any experience of these?

Now the 853 motor spins up so easily I could make a useful weight saving here which is my next plan.

I know I will need a new charger but what other issues might there be?

There's a discussion on the SX Forum about them.

They're not cheap https://www.rad.eu/nl/c/p/41019-shido-l ... 12b-bs.htm" onclick="window.open(this.href);return false;

But the general consensus is they're better batteries with fewer issues. Most owners don't charge theirs. Cold seems to be the only issue you need to worry about.

As far as weight saving goes, there are better options. For a start I'd look at unsprung mass.

If the battery doesn't need replacing I personally wouldn't bother. That said, you'd free up some space under the seat which might enable you to carry your big testies easier

I tried them....they were utter crap and WAY more bother than they were worth. True, they do free up some space under the seat for storing sandwiches & ciggies, etc.....but like-as-not you'll only end up having something to snack on while you wait for the tow-truck to come and pick you up.

The 'weight-saving' is not even worth bothering with on something that weighs over 400lbs.........it's the fat chick who buys a McDonalds McMassive burger combo meal with a Diet-Coke thinking the flab is just going to fall off her. It's not.

Shorai have a very good reputation on the SP forums Duke.

Most cost effective method to drop a few kilos and good mod IMO.

Do you trickle charge yours? From what I've read these batteries prefer to be left alone and work best at about 75% of their normal charge

[Blade]

I don't have one Kwacky but been very tempted for a while now.

I believe your correct in that as long as no current the draw they will hold a charge for a long time. If the bike is laid up I believe just disconnecting the battery should be OK but you can specific trickle chargers for them if you wanted too.

[Kwacky]

I looked into them for the zx6r. My biggest worry was the bike being outside and so not starting if it was too cold.

Given the size of the SX I can't see the point in them but it's worth it on a decent sports bike IMO.

[Blade]

Don't quote me but most of the Shorai ones if I remember correctly had more cold cranking amps then their regular counter part, conventional battery of similar size.

^^^^

You're right, they do.....but with that, they blow their charge out very quickly....can't have one without the other. The 'race-pack' I had was rated for 4 starts, so you figure on three.....the 4th is a bit iffy.

One of those things I wish I'd never bothered trying.

I have one for the rs250 they are Very light and small. if your looking to save weight they are a great addition.

You have to be a bit careful when storing them ie when the bike is not used for a long time disconnect the battery as you don't want to fully discharge it. It will hold charge when disconnected and is bad practice to keep recharging them.

[duke63]

Its not something i would have considered before but with the lightweight engine internals in spins over so easily and quickly even when cold.

What make do you have, rocket?

[rocket]

it is a http://www.racingbatteries.co.uk/index. ... 34-rbf1000

This battery came with one of the bike's i bought it had been stood for some time. I gave it a charge using my rc charger that i have and its worked spot on since.

It is very small but there's not much to power on the rs250.

[Blade]

That must weigh the same as a pack of fags

[Cav]

Just saw someone post about this on Trackday Addicts and shared it to the Tankslap FB Page...

Stock R1M battery - 2kg
Lithium Battery - 0.5kg

[Blade]

On older bikes and especially vtwins which traditionally have quite large batteries I've heard of weight saving in the region of 3 to 4kg.

Not from the unsprung mass admittedly but usually carried quite high up on a bike so large benefit and a cheapish and effective weight saving for any project bike IMO.

[Cav]

If you find yourself saving 3-4kg from a battery on top of: 3-7kg from the exhaust system (bike dependant), 2kg from the subframe if you do a single seat conversion... you really start to make headway.

I never realised just how much of a saving you make with a lithium battery

[Blade]

I ve lost 20+ kg off my bike. Once you get the big savings out of the way as you listed above, you have to start looking at small 100 to 500 gram savings which people think is mental, but there are many which when added up can save another 5 ot 6 kilos.

This is why manufacturers update bikes and save 300g from a swing arm or 500g from the frame and people believe its madness but it all stacks up and there are only so many large losses to be made.

As far as kilo saving per pound(£) goes the lithium battery has to be the most cost effective mod IMO.
