Hey folks, Anyone still ride these bikes?

I recently found a bikemaster lithium battery that is somewhat affordable. I have always been scared to run lithium but it seems bikemaster has managed to incorporate a decent battery management system into the battery.

I purchased this one, have yet to install it. Amazon.com: BikeMaster DLFP-9-BS Lithium-Ion Battery - Black - One Size: Automotive

65$ For a premium lithium battery that is steal

They still recommend a lithium battery charger but its not for the reasons you might think. The battery's integrated BMS, battery management system will actually balance the batterys properly no matter what type of charger you use without risk of overcharge. The problem with non lithium automotive battery chargers is they do not actually produce enough voltage to charge this particular lithium setup which requires 13.5-14.5v to charge effectively according to bikemaster.

According to bikemaster this is also why modern bikes can charge this battery with no problems because our bikes produce the required minimum voltage to charge effectively. This is all dependent on the BMS, some cheaper knock offs don't have BMS built in.

Hopefully you have good results with the bike master you purchased.
I personally would not experiment with a lithium battery that was not tried and tested for many years first. Way to many issues experienced by many with cheaper lithium batteries.
Here is a great article by a very knowledgeable and trusted source, although the info is dated now by a few years you get the jist

I am right there with ya, i have always been scared of it for good reason. This particular bike master lithium battery has been out several years now and havnt found a negative comment about it except the occasional person who failed to tend his battery properly. Lithium wont recover from a complete discharge as well as lead acid but lithium doesn't discharge nearly as fast. These batterys are usually priced so high you couldnt even consider it, 150$+. So the 65$ price hit home with me.

I will just have to be mindful of storing it in direct sunlight for extended periods. I fly drones and have many lithium batterys, some of questionable origin. No fires or explosions, The key is a good BMS and according to bike master they have a BMS that is capable of charging past dead cells and cheaper BMS will create a block if there is a dead or weak cell in the pack.

Shipped out today for me, If i can get this thing to last 6 years it will blow my freakin mind.

Keep us updated on your experience with the battery please.
My stock battery is 5 years old so I'm sure I'll be due for a new one in short order.

Just Hooked the battery up today.

Couple small issues, I had to reroute some cables because the terminals were directional and in the wrong direction lol. Still got it all sinched up, I installed the quick connect for the lithium tender i purchased. The charger came with the quick connect cables, made sure everything was tight. A loose connection has worse outcomes for lithium batterys over lead acid. I had a slight problem threading the nut with the added connectors on the battery terminals, so i added a paper spacer under the nut just so i could get it to thread the bolt in the terminal.

I plugged in the charger and it ran the charge cycle for a few seconds and reported back charged, This charger has an automatic Tender function when not charging. You could just unplug the negative cable on the battery for storage and not have to worry about a tender. I decided to stay on the safe side because of the low recovery rate of a discharged lithium battery, So i will be using the Tender when i don't ride.

I havnt started the bike yet, It was late and i didnt want to anger the neighbors. Soooooon very soon.
Pics soon.

Started the bike, was hot..... still in the hot sun, If the battery doesnt have a meltdown while i let the bike breathe<before i put it in garage> then i guess it passes the heat test.

When i say start I actually warmed it up really good because it sat too long and had a rough idle. A very good way to clean up deposits in the system, My neighbors hate it though. If i have any hesitation in my throttle range something is wrong, Owned this bike seems like forever now and still sounds great That Yoshi exhaust really pairs well with the stock carbs and after i warmed her up there is zero hesitation when i snap the throttle through the entire rpm range.

If it wasnt so hot in the garage i would have took more pictures, A/C i installed takes a couple hours to cool effectively and I didnt have the patience. :-D

First off, this is not a "premium battery" by any standards; who told you so, needs to go back to training. This battery weights-in at almost the weight of a standard battery at 6lb and I perosnally don't see a reason for anyone to get the cheapest crap some vendors want to get rid of... You need to understand that not all Li Ion batteries are identical and there is a reason prices differ. I wold as well disregard the reply with the article which is deterrent to this technology; it's most likely written by someone tired of testing new stuff. When I do a reply here, I will only do it whit 100% certainty that it's something I personally experienced. I will never endorse a company or brand and I will always leave it to the person to decide for him/her or itself what to buy...
My PERSONAL experience with Li Ion batteries on motorcycles is a very positive one. It's the cheapest way to shave-off some weight without making ANY compromise; this being said, a 6lb battery does not qualify, regardless of the price-tag. I got about 6k miles back a Li Ion battery on my MV and it treats me extremely well; never ever did I have the slightest issue, never ever did it not turn or give me any other sort of headaches. This is Real and you please take a look at the photos. Anything else does not matter. The battery on my bike weights 2.13lb, while the standard one was 9.5lb... Have a good one!

Sorry it took so long to reply, In my profession I meet alot of people that appear to be more knowledgeable and they do so by trying to discredit other people around them to make them appear as if they know better. These people tend to embarrass themselves in the process and they don't even care because even they know they are full of it.

Ok, now on to fact checking. You don't like that the battery weigh's 6lb? You are basing that off the "amazon's listed item weight" that is wrong pretty often but if you read the item description from the seller it says the battery weighs 2.2 pounds. If you go to the official bikemaster site and look at the battery specs it weighs 2.2 pounds.
So that automatically tells me you did zero real research into this battery and just flashed over the listing. This battery is certainly a premium battery and most people that buy it are extremely happy.
You probably paid alot for your battery, if you care about the 0.07 pound then its all good.
Don't let this price savings fool you on the bikemaster brand, this battery retails over 100$$,It would help if you did a little research... or any research for that matter.

I think i mentioned this before but a BMS makes or breaks a lithium battery and this bikemaster BMS is superior to other Lithium brands. Research, Research, Research.Most BMS will have trouble charging past a weak or dead cell, Bikemaster solves this problem with a more advanced BMS.

Now for status update of battery,
I am super impressed how well this battery holds a charge and i do notice the increased cranking amps. I am not afraid to recommend a product I believe in.

Please anyone reading this please disregard ITRoberts post and do your own research. Something Mr. IT did not seem to do.

@ITRobert and everyone else

You inspired me to do more research, not on the highlighted issue but into cell type.

Shorai Utilizes Prismatic cells, while Bikemaster Utilizes Cylindrical cells.

While Shorai boasts its cells military applications, lets dive into the dirty.

Prismatic Disadvantages
Prismatic cells are made up of many positive and negative electrodes sandwiched together leaving more possibility for short circuit and inconsistency. The higher capacity makes it difficult for the BMS to protect each cell from over charging and dissipating heat. The larger cell size minimizes the possibility for automation leading to a lower degree of consistency. The internal electrodes can easily expand and contract causing deformation which can lead to a internal short circuit and are more prone to swelling similar to lead batteries.

Cylindrical Advantages
Compared to prismatic cells,electrodes in a cylindrical cell are wound tightly and encased in a metal casing, This minimizes electrode material from breaking up from the mechanical vibrations, thermal cycling from charging and discharging and mechanical expansion of the current conductors inside from thermal cycling. Many cells are combined in series and in parallel to increase voltage and capacity of the battery pack. If one cell goes bad, the impact on the entire pack is low. With prismatic cells if one cell goes bad it can compromise the whole battery pack. Cylindrical cells radiate heat and control temperature more easily than prismatic cells.

I personally Decided on Cylindrical style after seeing far too many pack style cell's become toast, Literally.

Mate, keep it simple; have fun with your battery! In fact I don't give a raccoons ass about what battery someone uses and the price of the Shorai doesen't prevent me from buying a second and a third one when needed. Stay happy with what you got! I know for a fact that I have zero issues with this bike and with the battery and that is all that matters. I was not disrespectful and you act like a child. Get back after two winters and let us know how it worked-out! Stay safe, mate!

This falls into my original statement that people like you don't even care when they are proven to be full of shit because it happens fairly often.

By what you put-out, I will rate your age at about seventeen. Now, here's some adult advice which will take you a long way in life: Turn down your anger by about 90%, learn how to be polite, understand that nobody means harm to you. I would also recommend attending some school due to your age. Never blame others for your own decisions in life, which won't take you to fulfill your goals. You want to hear that you're brilliant, spent your grandma's Christmas gift wisley on a battery, which happens to be the best battery in the world. I understant this battery means the world to you and I wish you many, many happy years together. If this will help you in life, it only depends on how you will (or not) follow my advice. I still wish you all the best, stay safe, keep your rubber on the asphalt and value this community for what it is!

You have been here a whole 5 months, I have been here since 2006. guess that was my birthday huh?

I suggest you let the veterans give the advice and stick to trolling other peoples threads, leave mine alone.

In fact I had to sigh-up again because I forgot my credentials... But that's not important. What matters is that you have no manners, you might have a different age, but your brains forgot to grow-up. Like I said before, be polite and respect the community! Besides that, stay safe and keep the rubber down! One ,more thing, you would never have dared to tell me all that crap in person; just saying...

You are so predictable, First I call you out on your false information and then you start your discrediting campaign against me. You don't even try to dispute anything i have said you just start with personal insults. Trolls will be trolls.
