Lithium Battery Motorcycle Charger

Asgood as lead-acid batteries are, they have some significant flaws. First, they are heavy. Second, they contain a large amount of lead, which is bad for the environment if not recycled, and the acid that interacts with the lead is corrosive, should it leak from the battery case. Third, they have a limited number of discharge/recharge cycles compared to lithium batteries. Finally, in storage, their self-discharge rate can be as great as 1% per day in hot conditions. Lithium batteries address all of these issues.

To learn more about lithium batteries, how they relate to lead-acid batteries, and what the future holds for them, we talked with Representatives from two of the major lithium battery manufacturers in the U.S. At Shorai , we spoke to Phuc Lam, TK, for information about how Shorai has approached lithium batteries over its 11 years of manufacturing them. We also spoke to Jason Levitt, President and Founder at Full Spectrum Power , whose company has also been a manufacturer of lithium batteries for more than ten years.

Additionally, in the case of powersports lithium battery failures, most of these occurred in batteries without Battery Management Systems (BMS). The electronics necessary to balance the discharge/recharge loads on a lithium battery have advanced to the level that the BMS shuts the battery down when an overcharge situation that could potentially lead to overheating and/or fire is encountered.

Another myth about lithium batteries is that they are less resistant to parasitic drains, such as an alarm system. Again, this comes from the era before lithium BMS were common. Typically, the alarm or another accessory would completely drain the battery, and the owner would not notice this for a while. With a lithium battery, this extended flatline will turn it into a paperweight. High-quality lead-acid batteries may bounce back from this kind of abuse a couple of times. However, not all lead-acid batteries will survive this mistreatment even once, either.

Finally, when it comes to longevity, lithium batteries have a conservative discharge/recharge cycle capacity two-to-four times that of lead-acid batteries. So, if a lead-acid battery can last around 500 deep discharge cycles (or 80% depth of discharge cycles), a lithium battery can perform the same task upwards of 2,000 times, negating much of the upfront premium price paid for lithium batteries.

As we said at the beginning of this article, the most common advantage that most riders have heard about lithium motorcycle batteries is that they weigh significantly less than lead-acid batteries. This is true. Getting roughly 70% weight savings is fairly common, and even lower weight options are available for those, like racers, who want to get the maximum weight savings. While this might not be of great concern to the owner of a Big-Twin bagger, sportbike enthusiasts frequently spend a lot of time and money shaving weight off of their bikes. Switching to a lithium battery could be the easiest way to lose five pounds. It certainly beats dieting.

Also, lithium batteries operate a higher voltage than their lead-acid counterparts. Lithium batteries produce 13.2 volts, delivering better performance to all the voltage-dependent systems on a motorcycle, from the starter motor windings to the coils to the injectors. With the better voltage-stability and slightly higher voltage delivered by lithium batteries, you get a bike that is easier to tune and makes more horsepower.

so wears the safety as one as said .working on a kymco 125 rs today fitted a lithium 12v .checking out put meter all over the plays engine running . battery vaults 13,26 .engine off . now the battery is swelling only on the bottom bought second hand ebay . seller 3 blue lights , had it over 10months . your right if the bike dose not charge propyl the battery will lose vaults. If you see one blue light .it need charged

yester day i came across a selling a safety board .to stop the lithium from 15v. over charge . for a motorbike . if the rectifier drops out and over charges . lets see if there it a safety mod out there . the battery makers should be looking at this , have you seen on Microsoft .a small scooter in a down stairs burst in to flames in the night camera picks it up. have you ever read a lead battery go on fire .they can blow up on the bench .as i no this but never on a bike, just my findings .thank from john. 12.33pm 2752023

Are there issues with Lithium batteries I should know about?

Yes! FastBikeGear's product manager, Liam Venter has a background in electronics (New Zealand Certificate of Engineering, telecommunications/radio/electronics). We spent some time researching LiFePO4 batteries for motorcycles and looked at many suppliers. Initially this was a frustrating exercise, because while there are many advantages to Lithium batteries there are several potential and costly issues thhat can all be mitigated by good design. We discovered many brands on the market were just interconnecting raw lithium cells in a plastic case to create a crude and unreliable battery.

With this simplistic approachh there are several potential issues that are not being mitigated, such as:

Are all Lithium batteries are made equal?

There are still some lithium battery vendors offering batteries without a built in BMS (Battery Management System) or any internal safety protection devices. Batteries that do not include inbuilt Battery Management Systems and protection circuitry have unfortunately tarnished Lithium batteries reputation for reliability and confused customer expectations on what life span that they should expect from a lithium battery. Hopefully batteries without inbuilt BMS systems will shortly become a thing of the past.

If LiFePo4 batteries are charged without a BMS (Battery Management System) the internal cells do not charge evenly. This can lead to greatly reduced battery lifespan in many cases to as little as 2 or 3 years. Most european manufactured lithium batteries now have a BMS built into the battery to protect it and ensure it is being properly chharged while you ar riding the bike.

Manufacturers that still do not make batteries with a built in BMS recommend that you also purchase an external mains powerd BMS charger when you purchase their Lithium batteries, so that you can perform periodic cell balancing. Of course this does not provide the required protection, cell baancing and other BMS functions while you are riding the bike (which is of course when thhese features are needed most).

In the picture below of the battery with the top cut off you can clearly see the BMS (Battery Management System) circuit board.

When you consider that most people change bikes every three years then the very high failure rates (25% within three years) of lead acid batteries becomes more acceptable (because the battery becomes someone else problem).

Unless you can swap your lithium battery from one bike to another, you could lose on the deal when the next owner gets your reliable long life lithium battery and you may get a bike with an old lead acid battery.

Modern motorcycles are usually equipped with 12V batteries. Battery chargers for motorcycles are essential tools for bike owners, especially for people who only use them in summer, or for recreational use, leaving them stored for long periods of time.

Lithium-Ion batteries are similar to LiFePO4 batteries, but they are more volatile (they are not recommended for hot weather), and they have a shorter lifespan. They can hold a charge for about 300 days but are not as versatile as the LiFePO4 batteries.
