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

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 bought the battery in October and installed it in my 2023 Harley FXLRS. Put about 3,000 miles on the bike with this battery. It worked great until it didn't. Last week I had to make an 80 mile round trip into Phoenix to pick something up. As I was getting to my location, the ABS and TC light on my bike started going on and off intermittently. I figured my ABS sensor had gotten dirty. This continued as I rode back, and when I was about 20 miles from home in the HOV lane, the bike shut off with no warning whatsoever. All gauges black, one second I was riding, the next I was rolling. I coasted to a stop on the inside shoulder and ultimately got stuck there for 3 hours during rush hour trying to play roadside mechanic and ultimately waiting for a family member to pick me up with a trailer. Several people stopped to give me water but I still got home sunburned and dehydrated. Got the bike home, pulled the battery, and it reads 7.49 volts. I contacted Weize requesting either a refund or an AGM replacement (never doing lithium again). I haven't heard back. This battery gave up the ghost essentially without warning and at the worst possible time, leaving me in a dangerous situation for hours. It's your money, but I wouldn't do it.

Purchased two of these, one for my jet ski and one for my 4-wheeler. Both were perfect fit (same size as the batteries I replaced) and the power was amazing! 700 cranking amps starts them both right up. My Jet ski has always been a hard crank even with a new battery, but with this it fires right up. We will see how long they last but I got no complaints so far.

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.
