WEIZELithium YTX30L-BS, 700A Lithium LiFePO4 YTX30L Motorcycle Battery, 12V 10AH ATV, UTV, Jet Ski, Scooter, Lawn Mower, Tractor, Generator Battery, Built-in Smart BMS

I purchased this Weize Lithium YTX30L-BS battery for my 2003 HD Road King Classic. The last battery's cranking amps were slowing dwindling and required frequent charging over the last few months. Easy enough to tell as it lagged a bit at start time. The old battery originally had about 400cca but this new Weize Lithium touts 700cca. And of course, there is such a HUGE difference when you hit the starter. Now, it cranks the Road King right away with no hesitation.Out of the box the battery registered 13.6 volts. I topped it off with an appropriate lithium charger which settled it in at 13.8 volts before installing. The battery was a perfect fit and the terminal blocks well placed for easy connection of the cables and lugs. This Weize battery weighs in at 6.2 lbs. enabling me to set it into the motorcycle battery compartment with just one hand. Nice quality hardware included in the package for connecting the battery cables.So far I am impressed with its performance. And after having said that, only time will tell as I only received this battery yesterday and installed today.I've read that this unit is designed as a "starting" battery and not really to be used for extended discharging of high current items for long periods of time. Since the Road King has no power sucking lights or motors or other items that would draw high current continuously this battery should work just fine for a looooong time!

Had a battery going bad on My Harley, cranking slow! Removed it and noted it was about 9 years old. Pitched the Battery, installed the new one and when I pressed the Starter button, I was Shocked at how Powerful it was and how quickly the Bike started. I would Highly recommend this Product!

I bought this battery last year as a cheaper alternative to NOCO (which is a straight-up excellent battery) It fit my bike, it had zero issues staring and running my bike all season (HIGH compression Buell 1203 built to the moon) Then, I left it in the bike all winter, cause I'm lazy like that. I live in Maine, winters are COLD. Several weeks of sub-zero temps, warm ups then freezing again. Went out this morning at 34 degrees and hit the start button.....that battery hit hard and strong and after about 15 seconds the bike fired right up. Try that with your $300 HD lead-acid battery.

I ordered this to put in a Kawasaki ATV. It was listed as a direct replacement for a YTX14-BS Battery. Nothing could be further from the truth. When it arrived I knew it would be lighter, but it felt almost empty. I decided to read the manual before doing anything. Right on the cover over the Manual it Said Starting Battery. I thought that was strange , then I started reading more.. It became apparent that this was a battery only for briefly starting the vehicle and nothing else. when I read the warnings it basically said do not connect any electronics without authorization or damage will result. I have uploaded the manual pages here. I messaged the manufacturer to tell them I had a winch, stereo and light bar on my ATV. Here is the response I got"The Weize Lithium YTX14-BS battery can provide sufficient power for basic ATV functions.However, accessories such as winches, stereo systems, and large light bars typically require more power and may cause a sudden high load on the battery.Therefore, this battery may not suitable for safely powering all these accessories.You should consider a higher capacity battery that is designed to support high-power accessories to ensure safety."So, after getting that message and reading the specs break down which is also here in my review. I returned the battery. After reading the detailed specs I have a guess as to what this so called battery actually is. I believe they have some small number of 18650 Lithium cells or some other model#. Then they have two or maybe more capacitors in there. When you start your motor you get a 3 second 500cca burst from the capacitors which then turns into 200cca for 10 seconds according to the manual. And that is about it. then while you ride it will recharge the Lithium batteries which will charge the capacitors. At best this is a Hybrid battery that as the manual says right on the cover is a starting battery. It really cannot do anything more. I cannot imagine having this battery in a very cold climate where you may encounter hard starting. This battery would be useless I buy lots of AGM batteries from Weize that are always a good performer as well as a good price. This is not one of those batteries.

Update 2: it has finally died:( While the multimeter still shows about 13V of the charge the current isn't about to crank up a small 250CC engine. The battery has never been in a cold condition, never was a subject to a full discharge. However, the customer support is great and they quickly helped me to resolve the issue. 4 starts!Update: 3 months in and the battery works fine so far. I have a bit of a scare yesterday when I could start the motorcycle, but turned out to be a loose kill switch screw :)Original: Great battery so far. It is light, the installation is easy. The package includes three different foam padding so you can add needed height to match the form factor of a larger battery (like TX9).Float current stays at about 14.5V which seems to be the high end for lithium batteries. I wonder if the alternator will be able to charge t.Cranks my bike super fast. I will try to report later when I have more experience with it.

So much lighter and so much more power. I’ve owned several Harleys and I can tell you they always caused a bit of worry when starting. Always that low turn over of started and the occasional lock up and restart. This battery cranks a lot faster and the bike seems to run better (I know it’s not) and I’m much more confident hitting button.
