Received a free Lithium battery from one of my wholesalers. He asked that I do a review and send it to them. Looks good so far. Same size as our YTX7A-BS batteries that weigh 5.5-6lbs. This one weighs 1.2lbs. It also has almost twice the CCA of the YTX7A-BS. As a test I tried it on a Kawasaki 500 UTV that has a 10 amp battery. Cranked it over like it was nothing. More to come when I finish the review....this thing looks promising! Also has a built in battery charge level meter so you did need to dig out your multimeter.  Attachments:

Same with this one..did not know they are feather light. When I pulled it out of the box..I almost tossed it across the room. It was like back in the day of cardboard Milk cartons..not knowing it was empty ya reached into the fridge prepared for the weight...and BAM! ya jerk the carton up so hard ya hit your hand inside the fridge...lol..  Survey..be honest..anybody ever done that?.. ;D Shorai are ok but at $169.00-$200.00 I can almost buy 3 of these. One customer had a Shorai in his Vespa...was a nice battery but getting the charger's clips on it was tough as there is not much room on the battery. Regardless..as the battery I linked to above...it is cheaper than the AGM I linked to and other sites I found them on....and the Lithium one has twice the CCA. It cranked a Kawasaki 500 UTV..so today I am going to mess around and see what else it can crank. Thinking my Hayabusa 1000cc... ;D |

Never did the refrigerator thing, but I have flung stuff thinking they had weight. The reason you found the Shorai so tough to charge is that they have a dedicated charger (just for Shorai) that PLUGS into the battery (you've got to be careful as ordinary chargers can damage them.) Good luck with your new battery.  |

Aha...thanks did not know that..wondered what that lil port on the battery was for.  Eek..but the special charger they need is $70.00..looks like I am a bit too poor for a $160.00 Shorai Battery and $70.00 charger for it...  |

Li Batteries have greater cranking amps.
That allows them to run with less cells.
This, paired with the ~4 years lifetime of a cell, causes these batteries generally not to be a very good purchase (2 years for a $25 Lead/Acid battery, 4 years for a $115 Li battery; you do the math!)

Then why do  % of folks lead acid batteries here only last one season? $115.00 for a Lithium? Here you do the math www.ebay.com/itm/7A-BS-Lithium-Ion-Li-ion-Scooter-Powersports-Battery-/171007258460?pt=Other_Vehicle_Parts&hash=item 27d0d3af5c&vxp=mtr They plan to sell them from their shop for that price as well. I know another you gotta negate every post I make. Jealous cause I found these and not you. But as always EVERY post I make you negate. Shouldn't you be 'speculating ' more of your off the wall schemes likr the ones you post... i.e. gonna make your 50 a 30cc to get better gas mileage...or decrease a 50cc jet size from the stock 74 to a 64 for better mileage. Or anyone of your way out there and outlandish dreams and speculations that you post as 'FACTUAL' which really puts our new scoot owners and wrench turners at risk of ruining their scooter. pfft..keep negating everything I post...I need a good laugh.. btw..notice how many times folks have said "Thanks carasdad that worked" or helped them or whatever. Yet we have not seen one for your...ahem...I guess you would call them contributions. But then skuttadog..alleyoop..hank...fugaziz...and SO MANY others get a thanks for their help and contributions and help. You get none..so you feel left out. Many of us do find it very entertaining that you just HAVE to be the expert on everything...Keep it going.. I always enjoy a good laugh...and it sure is cheaper than paying for Cable TV to watch Comedy Central...  |

a higher cranking battery isn't need in a stock scoot, the 7ah regular battery even cranks the cheapie ebay bbk's, its when you have a 52mm or a higher quality bbk with more compression, something is needed if the lithium can crank over my 52mm kits i'd be a happier guy, so more than likely i'm gonna have to go this route, i'll post after i get one, already posted the before vid

The lithium batteries are the wave of the future. But one needs to use a special charging circuit for them though. A regular battery charger won't be able to charge them properly without damaging them. The lithium polymer batteries can be dangerous as if something happens they can go bad and burst into flames on you. The more safe LiFepo4 batteries don't normally catch fire and thus would be more wise to use. You see the LiFe batteries in the hybrid and electric cars for that reason. But with a good LiPo or LiFe battery charger the batteries would have a much longer lifespan over the old lead acid batteries. One problem with lead acid batteries is that because of the lead and acid too, no one wants to make them much anymore as it is so environmentally dangerous to do so and becoming very highly regulated as well. Worse is the batteries seem to be getting worse and worse as to quality and are going bad much faster than they used to.

earlwb - Funny that you mentioned LiFe, as we are currently working on a line of LiFe batteries of our own. We've come to much the same conclusion about LiPo: While very effective, there is a certain liability when using them that I'm not quite comfortable with yet.
This being said, LiPo is a very attractive battery tech for all of the above reasons that Carasdad is discovering.

This being said, LiPo is a very attractive battery tech for all of the above reasons that Carasdad is discovering. Matt Matt and earlwb...I am not an electronics tech..that was my dad..I was a 21 year USMC Combat Medic type. But my dad drove electronics theory and formulas in my head daily hoping I would follow his footsteps...but by the time I was 18 I was sick hearing about Ohms Law...lol...so I joined the service. ;D Can you guys or anybody explain to me..why prodigit says a 4 cell vice 6 cell battery has a shorter life span and that Lithim Batteries are basically no good. I know he is loaded with facts such as you can take the #74 Jet out of your GY6 50cc scoot..put in a #64 and get better gas mileage. Which tells me that Florida's environment is different than the other 49 states as we would suffer a severe lean run and engine destruction. Also he can make a 50cc a 30cc get the same speed and better gas mileage. But why would a 4 cell battery have a shorter life than a 6 cell lead/acid as he says. Confused cause the Tactical 1,000 yard light on my Tactical fully decked out 30.06 has a single cell Lithium battery.. That is even less that his 6 cell and my 4 cell ones..it is only a single cell. I have left it untouched 6 mos or so and it NEVER lost a drop of current. It illuminates 8-10 hours..is 2 years old and STILL works as well as they day I bought it. Never fails to charge..it just keeps going..and again it is only a single cell. I tried to research 4 cell vs 6 cell 12v batteries and find nothing about them having less life span. Either of you know why they have less life? I'd ask the expert but he don't like me..has to negate EVERY post I put up...or every discovery I make...tip I find..or helpful hint. Huh..anyway.. Ok latest venture with the "Freebie" do a review Lithium battery. We cranked a Honda CBR 1000...spun it right over. Then jokingly my neighbor said try it on a car!! Said his wifes car was low and would try to kick in but not enough to crank it. I said ..yeah ok..a 2.2 liter 4 cylinder with a scooter battery. But he dared me and it is not even my Battery. So we used jumper cables..it cranked slowly but DID fire the car up. Bad part is it really stressed the battery. It was too hot to the touch. Its onboard push button level indicator would not even register...just a few blinks now and then at 'Low' Hope I didn't kill it...I was having fun. On the charger now and taking a charge..so hoping we did not kill it...  |

This being said, LiPo is a very attractive battery tech for all of the above reasons that Carasdad is discovering. Matt Matt I used a float charger..not a regular charger as it only goes as low as 2 amps..and they told me that was too high. So far after abusing like I did in the above post with a partially dead car battery...which made the Li Po too hot to touch almost. It did take a full charge...which really surprised me! So they are tough critters...but yes...charging them must be done EXACTLY as the wholesaler that donated it to me to play with and test out said. It kept a full charge after 36 hours in my freezer even. But that does not indicate what 3 months of winter weather would do. Where can I find info on your LiFe battery? Does it need a special charger? The Shorai does and that is a $160.00 battery and $70.00 charger...so the market for them might be slow unless ya got a big bank account. This has worked fine on a trickle charger...no explosions yet *counts fingers*..nope..no explosion. The hard part about the Lithium batteries I have found..is when I show it to folks and tell them I can order them one. They are very skeptical as it is so light... 1.2lbs vs their 6lb YTX7A-BS...so they don't relate it to having more CCA. But that is human nature with technology i.e. when radios went from tubes to transistors they were smaller and lighter and many had no faith in them.. |

% of folks lead acid batteries here only last one season? $115.00 for a Lithium? Here you do the math
