Weize Lithium YTX14-BS, Group 14, 500A LiFePO4 Motorcycle Battery, 12V 5AH ATV, UTV, Jet Ski, 4 Wheeler, Snowmobile, Personal Watercraft, Seadoo, Polaris, Generator and Riding Lawn Mower Battery

This is the best battery ever. I have installed this battery in two of my generators, a 13KW DuraMax and a GenMax inverter 9KW and in both cases the electric starter starts every time, even if it's been 6mo since I started it, it still starts great. I never have use a battery tender anymore. These just keep a good charge for a very long time. It fits perfectly in the generator mounting space. I think it's actually smaller than the original lead acid battery. I simply use the built in charger from the generators. I haven't had any issues with charging at all. Fantastic battery for the price.

Purchased for our 2013 HD RoadKing. The old Harley battery was starting to show its age and required frequent time on the trickle charger. Also had a lag when hitting the starter even though it never failed to start the motor. The old battery had about 375cca and The new one has 700cca and there is a big difference when you hit the starter. Now, it cranks that baby right away with no hesitation. This battery also weights at least 20lbs. less than the lead acid battery it had, therefore it’s way easier to remove if you need it to. The battery showed 13.5 volts right out of the box. It came extremely well and meticulously packaged. You can see the great quality of the terminals and the new hardware provided. The size was a perfect fit on the RoadKing and the terminals perfectly placed for a great connection and this made it an easy to do so. This was a great value when you compare it to others like product if you can even find one as impressive. Just a word of caution. You will need the proper charger that can handle the Lithium battery. A standard charger will not work on these so you will have that extra expense if you don’t already have one as I did. The durability is still an unknown but having used similar lithium cell batteries, it’s very unlikely that they will fail. When they’re bad, you will know right away. Just my personal experience with these. If this battery durability or performance fails? I will be on here immediately to report any issues, I assure you. In closing, I highly recommend this battery.

I thought my Harley battery was ok, maybe a little older and weaker than new but ok. Got some grinding when trying to start it a couple times so I was concerned that I might need a new starter. It usually started ok and ran fine but one day after riding to the DMV when I came out the motor turned over slow, made the grinding, continued turning slow and then fired up! Went straight home and parked it and put it on the charger. It showed charged fairly quick so that's when I started wondering about the starter. Long story short, I had started to suspect the battery and one day after putting it on the charger when I came back to check on it the "Trouble" light was on. Researched some batteries that day and ordered this one and now it turns over the motor easily, haven't had an grinding at all and it fires it up so fast it actually startled me the 1st time! Ordered the lithium iron charger with it and charged it up before putting it in the bike. Install was easier due to the threaded posts (with provided bolts)-another reason I ordered this over others as it was enough of a pain to install because of the short pos/neg cables without having to fight with holding the battery AND a tiny nut while trying to thread in the bolt! Finally, the 5 year warranty is a plus in offering some piece of mind that I hopefully won't need to worry about it for quite some time but if I do, being a name brand, they will take care of it. Very grateful this seems to have taken care of my problem and I don't need a new starter! 5 Stars

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.

Replaced the battery in my zero-turn mower last year with one of these it holds a charge much better than the old lead acid battery it came with and lots more cranking power.

Light (compared to conventional battery), durable construction, and I believe this is my first battery with threaded posts. It's nice to not mess with the square nuts needed for what I'd consider a conventional motorcycle battery. I was very careful with the battery dimensions to ensure it would replace my existing dead battery (it was perfect!). I was not careful enough with the battery posts. My XVS1300 has angled tabs on the battery cables that are supposed to help seat the cables properly? I needed to shave 1/8 inch off the top-back edge of these posts to align the holes of my battery cables with the threaded terminal posts. It was minor and cosmetic (as far as battery function goes), but if you don't have a grinding disk or dremel handy, you might have problems making this fit. Make sure your battery cables are flat, or that you'd have enough cable length/flexibility to mount to the front of the battery terminal (which is skinnier), or your posts match. I also purchased a new battery tender that was compatible with this advanced battery type. An older, conventional, charger isn't recommended. The bike now starts quickly/easily and I'm looking forward to years of dependable use.

Frankly speaking the LFP battery is great, BMS puts out over 500 cca. Exactly as stated but I needed a battery with positive terminal on the right. Technically this has an L in name like YTX-14L BS. So I made a mistake and tried to return my unused, new, LFP battery in the original box. So I get a return authorization and print the label. Oh it says purchaser must pay postage, OK, I can absorb a couple of dollars for MY ordering mistake. But wait, this is where it gets really evil. The return address is a PO Box in CA. Because it’s a LFP battery package must go by ground and special handling. Cost $56.04 for me to return this $99 battery. No thanks, I will keep it. What you need to know is that it is cost prohibitive to return this battery because the company has intentionally made it too expensive by selecting a PO BOX. If you buy one, know that you really can’t afford to return it.

So far, so good. 2013 HD FLTRU - starts right up with no hesitation. • Battery well packaged - battery is larger than my last lithium, but fits in the battery well, with a slight bit of play. • Terminal is top-mount, and it’s a good looking battery that no one will see. • Comes with new terminal cable bolts - throw away your old ones‼️ • Arrived at my home fully charged, which was a plus 💯 🔋 Time will tell on this bad boy - I will be back with a follow-up.
