I'm familiar with lithium iron but in a different capacity. They work well but don't like cold weather, you have to wake them up.
Charging can also be an issue but if it's specified for motorcycle use I would hope they have that figured out.
I bought Shorai Lithium Iron Battery LFX18A1-BS12 from Revzilla after my warranty ran out last November. Last winter was fairly mild in NJ and i didn't have it on a battery tender. After 3 months it did fire up without any issues. I am planning getting a battery tender for this winter. I'm looking at the Nocco Genius, they do have an option for lithium batteries in addition to AGM. Shorai does make a battery tender but they aren't sealed and i'm worried they won't work in partially wet environment.
So far I like it, I shaved off 8 pounds of weight. The Yuma/Bmw battery weighed about 10.4 pounds and the Shorai weighs 2.2 pounds. Being that the battery is smaller, they give you styrofoam blocks to put around the battery to support it. The only gripe I had with the Shorai is I wish they had longer screws for the terminal. I installed a line for a second set of heated gear when I installed the battery. Cramming two sets of heated gear along with the battery pigtail and the battery was a bit much for the Shorai screws so I had to make a trip to the hardware store to get longer screws.
Lithium Iron I would not do. Just look at the problems in the aircraft industry. UPS flight 6 burned up in flight, all the 787 aircraft that have had battery fires have been Lithium batteries in confined places such as our battery locations.
Although not as common as lithium batteries, occasionally lead acid batteries will blow up. One of the first jobs I had as an auto mechanic the owner of the shop told me he had
a six volt battery blow up in his car (old cars had six volt systems). I forget what kind of car it was, but, the battery was under the drivers seat!! My wife's Subaru had a battery blow open into two pieces. It happens. Today, Samsung recalled it's latest phones due to them catching fire.
Recently replaced my AMG with an AMG. The guy at Battery Plus asked what it came out of then said BMW bike usually only last a year. Possibly in this warmer weather the original may only last a year. That was the original battery, has anyone had problems with batteries?
Same here, battery tender, original battery, 2013. My last bike, a Silverwing, I replaced the battery at ten years, even though it was still going strong.Always kept it on the battery tender. Hmmm, that means my battery tender is 15 years old, wonder how long that will last??
Lead acid batteries will blow up sometimes when a load is put on them or charging them while they're frozen. I had that happen in my truck when I lived in the arctic. Apparently the hydrogen that normally vents out of the battery case can become trapped due to frozen over vents. All it takes is a bit of a spark when you put a load on the battery or charge it. When it happened to my truck it was about -40F and we were doing a jump start. Pieces of the top of the battery made a dent in the hood which was up and chunks of battery and acid seemed to be everywhere. Lucky for me that I wear glasses because I got acid on them as well.
Just went thru this thinking process. Sierra BMW said if I got a Li-Io battery (which they sell) I'd have to make sure my battery tender did not have anti scaling. Li-Io is great technology. It does have some idiosyncrasies that I didn't want to deal with. My replacement AGM cost $80. Long story short - stick with AGM
