Ditto, their fantastic...I can let a bike stand for months and it’ll fire a bike into life in a millisecond, currently the oldest lith I have is over 6 years old and still good.

 

I have an optimate lithium but I've had two batteries die after 6 months and I think it's because I was charging them every weekend. My third lasted a year and is still perfect with almost never charging it.

Although, after hearing of someone who almost lost their bike to a lithium battery fire, I've replaced mine with a lead acid. It works as good if not better than the lithium and I'm confident it won't set fire to my bike/garage/house.

The extra weight is negligible.

 

I've got all of mine on a smart plug.... They come on at 2am in the morning then switch off at 7am then they're topped up and ready... Saves electricity and gives them time off charge... My oldest one is 4 years old and still good...

NOCO genius is a good lithium charger. iirc, quite a few of the lithium batteries are made by skyrich, but they just get rebranded. I agree with the above, they hold their charge for ages.

 

I use a tender as they've all got battery backed trackers..

Ive got a zero gravity re start battery. It’s excellent. Can’t go flat. Plenty of zap. Not cheap but buy cheap and you get stock equivalent which is utter shite and can’t even turn over a 150cc!

 

My reason for asking is not for info relevant to Ktm/husky it’s a Yamaha Yz250x that’s going to become a leccy start bike this weekend. Thanks for all the recommendations guys.

 

Yamaha smoker with a leccy boot? Tell us more.......

 

Its after market just came out and just arrived. Panthera is the company. Been waiting ages over 6months! Its using the 2016 Ktm starter (yeah they’re shit) but the rest is their own design and it’s well made from what I’m looking at. recommended to do the Ktm ‘wet mod’ like on the pre17 Ktm smokers - you know the with atf oil. Anyways, I’ve fitted the new stator getting a spark so all good so far. I’ll make further progress tomorrow done enough spannering today time for a film and some large glasses of red wine.

......o yeah Panthera are nobs, they’ve spoken with Yamaha about the kit which to me if they sell loads good old Yamaha will probably want some of the action, can see the kit appearing in the yam power parts catalogue.

 

If you need to charge a lithium often then either you have a drain on the battery or the charging system isn't good enough. They will last several months without being charged.

 

Shido mate

 

They are all shite and expensive. Get a good quality lead acid battery and save money. I had two Shido's (one died after 6 months the other after 18 months) and two from Skyrich (OEM equipment) both died after one year.
They are light, they are not stronger than a good lead acid battery. The Skyrich of my Gasser costs 170 quid.

How many Yuasas is that [mention]steveman [/mention] must be at least three with a lifespan of 3+ yrs?

Those videos of the bikes on fire put me right off... can’t get sand at a metal fire though till it’s burnt through the airbox/seat. [emoji3062]

 

Yes, at least I'd get two of them or two of another, maybe better brand.

 

I fit Shido into both my old Husabergs about 5 years ago. They had little use back then and even less recently. Both bikes had a full year of not being started and then 5 days of use twice in succession. No fresh fuel or easy start. Never failed to start. Never charged other than in use.

 

A yusas 5 will not fit my new battery box. The recommend battery from Panthera is:

Antigravity Batteries AG-801 Lithium-Ion Powersports Battery, Sm...

Its £162 on Amazon!

Update: i temporarily connected a battery to test to see if leccy start works and I’ve not wasted my money - it works. The bad news is I’m having probs sealing the magneto cover stopping gear oil leaking out. The cables go into a rubber gromit via the bottom of the case, it’s a worst case scenario for sealing! At least on the Ktm the cables in at the top of the case. The original cover leaked badly but didn’t need sealing, I don’t think I’m going to be able to sort it, but if any of you have some recommendations?

 

You have put in a vent pipe? If noy it will pressurise and let oil out.

Sikaflex is the big daddy of sealants, but everything on mating surface will need to be clean.

No the instructions don’t say I should.

 

You cant put oil in without venting it!

 

I wouldn’t know. The clutch cable goes into the case it’s not sealed but is not a vent

 

Are you sure that the oem yam cover doesnt have a drain hole? That will need to be sealed up.

Put a vent pipe at about 11 oclock. Carb vent hose is just about big enough.

 

I’ve had two different companies in USA who both have international shipping not ship a lithium battery to the me. Is it me, or are lithium batteries not allowed to be shipped by air?

 

They're a royal pain in the arse to ship. I ship laptops overseas through my work, and half the time they come back again because of the batteries. And that's within the EU. You now need to ship them with a Dangerous Goods Certificate. Your USA supplier probably has even more hassle shipping into the UK/EU and can't be arsed with it.

 

Shorai Lithium-Iron
I bought one a few years ago from Mike54 on here,they're used on the KTM Rallye bikes
never been charged
my 350 was a pig to start,that battery had some hammering but never let me down

 

Updates: I’ve located another supplier this time in the uk of the Antigravity 8 cell lithium battery. I’m having to use this battery because of the limitations of my air box size - Thanks for the recommendations.

I’ve had a second attempt last night at sealing the magneto cover and am hoping when I get home I’ve not got 250ml of gear oil on the garage floor. On a not so good note, I had a dead short on the original lighting loom blowing a fuse which took some tracing to resolve (nothing to do with new leccy start loom) The new rectifier has a spare DC output cable which I’ve soldered a connection to the lighting loom and as an extra precaution ive ordered a earth strap lead for a Ktm (doesn’t need it). The lights are now well bright and the horn is loud the old stator had dog shit wattage output.

Next job is the spare front wheel needs new spaces made.
