Weize Lithium YTX9, 400A LiFePO4 Motorcycle Battery YTX12, 12V 4AH YTX7 ATV, UTV, Tractor, Generator, Scooter, Personal Watercraft, Seadoo, Jet Ski, Snowmobile and 4 Wheeler 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.

These batteries seem to be the real deal; 600 CCA's. Bought one for my Harley with high compression heads, it cranks up on the hottest days. One in the jet ski, it has sat for months sometimes and yet never fails to start. One in our Kubota powered house genset and now one for our Kubota B7300. Light weight battery with a ton of power.

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 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.

This battery is very light. Looks good and definitely turns my king quad 750 over very easily.
