I've been charging my 2020 ATAS on a NOCO 2x4 for 3 months without issue. It's also charging 2x Shorai batteries. I have all three banks set to the Lithium Ion setting.
HY110 lithium battery correct charger
Please can anyone help me regarding a 2021 AT and charging the HY110 battery? I understand it's a Lithium Ion battery and yet the recommended charger is an Optimate lithium charger but the manual for the Optimate states LiFePO4 only and states not for other lithium ion batteries. So I bought a Noco genius 2 but that states in the manual not for lithium batteries without a battery management system. It also isn't lithium specific and so I am worried about using it. UK dealers seem a little confused. Does the battery have a BMS? Should I use the Noco or a lithium specific even if it's for the lithium iron phosphate (and not advised to charge a Li Ion in the manual) I would appreciate any advice. Thanks.

I have one of these hooked up to my ATAS 2021 for the last month and not had any issues so far
I went with the Optimate Lithium 4S 5A TM-291 (USA model) charger for the HY110 battery as it is also compatible with li-ion and the charger recommended in the factory service manual.
"Battery Tender Junior 800" - just ensure it detects lithium (LiFePO4) and not lead acid when using with the AT's lithium battery.

I've been using a NOCO as well. Now I'm second-guessing that choice. 
I went the 0.8 optimate. Theres 3 options, the maintenance, 0.8 & 5 amp. With the supplied cables you can hook up a permanent fused in/out SAE connection.
This cable comes in handy for monitoring voltage with a meter. Checking for a parasitic drain while in storage. In which case leave the maintainer connected.

I have the battery tender with 4.5AMPs current rating, it works great and charges fast.
That sounds like alotta power.I have the battery tender with 4.5AMPs current rating, it works great and charges fast.
My powersports dealer suggested the Battery Tender Junior 800, which can charge both Lead acid and Lithium. He also said the Optimate charge is made by Honda. Surprise surprise!
Personally I just let mine set, but then too I ride all year.. It may set for a week or two before the roads are clear from ice & snow..
From the manufacturer of the batteries;
6 month shelf life unattached after 1 year recommended voltage check and top off as needed…
So really none is needed, if anything just start it once over the winter storage and it should be fine.
Or just pull the battery and store it inside if you are worried about it..

Mine has a tracker installed so has a small load constantly drawing, along with having a young family sometime i can go a week or two without a quick ride in the winterPersonally I just let mine set, but then too I ride all year..

I only have the tender connected for a day or two every week.
I haven't used a battery tender yet this winter season, but maybe I ought to - at least for the lead acid batteries.
Optimate Lithium (0,8A) always connected when it’s not on the road. Small tracker installed, otherwise I’d expect the battery to survive a couple of months.
I’m still wondering how a LiFePo4 battery deals with a 100% state of charge for almost its entire lifetime... This technology likes to be somewhere around 70% SOC I think,

I connected the Noco Genius 2 on Lithium mode and it went to green light, for fully charged, after a few hours. Reconnect to bike tomorrow. I will report back..
All good, so I can confirm Noco Genius 2 on Lithium mode works fine on the silly expensive Eliiy HY110 battery. I hope that helps a future confused AT owner.🙂
When picking up my brand new '21 ATAS last week, the Honda dealer told me I did not have to worry about the battery the first 4y, as its lithium and so much better. I intend to ride all-year, so am thinking he may be right. Any contrary actual experience here on that matter?
I have datatool tracker which may be the reason the battery couldn't start the bike after 6-7 weeks?When picking up my brand new '21 ATAS last week, the Honda dealer told me I did not have to worry about the battery the first 4y, as its lithium and so much better.

It is quite possible.I have datatool tracker which may be the reason the battery couldn't start the bike after 6-7 weeks?
Not unlike owners of cages with electronic rust protectors installed. They draw hundreds of milliamps of current when the car is parked and turned off. A few weeks of that, especially during cold seasons will challenge the cage from starting.
Another example is a HD V-Rod with an anti-theft module. It too draws almost 180 mA and within a week or two the bike won't start.
who would ever think of stealing a HD :-D ??Another example is a HD V-Rod with an anti-theft module.
