Weize YTX30L-BS Lithium Motorcycle Battery, 12 Volt 12Ah, 700CCA, Built-in Smart BMS, Replacement YIX30L, ETX30L BS LiFePO4 Battery for Harley Davidson Polaris Sportsman

It turned over as slow as my old battery! Disappointing! I returned it!

I got this for my Polaris 800 Sportsman. Worked ok when I first received it but seems like would be dead in 3 months. In the winter it could no start without a jump box or charger attached and this was under a year old. Will stick with AGM in future.

Given my previous experience using this on an aircraft with a Lycoming O-360, and my battery finally failing in my RX8 Mazda, I decided to give it a try. Given that lead acid battery prices have gotten ridiculous as of late, specifically a group 35 for my car was 219 for a cheap one, over 300 for a yellowtop, both rated at 640cca. Then we have the weight savings! This battery is 6.6lbs and the AGM Lead one is almost 44.OK, on to the fitment. This battery is both shorter and narrower than the OEM one, however, the foam that was in the packaging almost filled the gaps needed. I took off the traditional terminals, which was 1 nut, and attached the leads directly to the battery. In my case I had to use different hardware on the positive terminal as I had to put a spacer under, so needed a longer bolt.The car fired right to life, even without charging. After it got a bit of charge to it, the starter turns over really fast now.For the price, this is a tremendous value.

I was excited to try and compare this and a Noco NLP30. I put both on my charger for a day to make certain they were topped-off woth full charges. Bought "L" contact adapters to help with the different battery lugs. (Noco didn't need them)I have three Harleys; all FLH Baggers.The Noco turned my police bike over without issues. Time for the Weize to show its stuff. Lights are bright and radio came to life! Hit the start button and... Electrical system went completely DEAD!Disconnected the terminals and reconnected them. Everything looked fine. Hit start- DEAD again. Repeated this process 3 or 4 more times.Next logical step was to swap the Noco NLP30 into the bike that kept shutting down. Maybe it only liked lead acid or AGM batteries.Nope - the Noco cranked her over right away and she purred like a kitten!Seize got packed-up and sent back today. Got another Noco NLP30 coming later this week.BTW - these are about 1/4 the weight of the AGM batteries. I just hope they'll last.

Been using this battery on my 2001 Yamamah F25 25hp outboard boat motor for my pontoon for couple months now. significant weight reduction compared to acid battery. stronger constant CCA. My motor starts right up. Lithium is the WAY lol

I purchased the lithium battery for my Harley with stock engine. As soon as you hit the starter button the internal protection device trips and shuts off the battery. Defective.Customer service is a call center that emails whomever. They want pictures of my voltmeter etc...jump here, jump there, oh, try charging it too. Load of complete BS. It has been over 3 days no response back after my reply. My old battery works much better than this POS.I would not recommend buying anything from this company. Supposedly a big warranty that will mean absolutely nothing when you need to use it and you likely will. At least with an agm battery you don't have the very problematic electronics in the battery.Just look at the 1 star reviews and you will see this is a problem for this company. I wish I would have! Buy one of these and you have nobody to blame but yourself. You have been warned.

The battery seemed to work well at first. But yesterday was colder (17 f) than other days and it would not even crank the snowmobile at all. Later in the afternoon when it was warmer (38 f) the battery worked fine and started the snowmobile. I’m very concerned about this battery stranding me in the mountains on a cold day. This battery advertises twice the cranking amps as my lead acid so It should have started easily, even in the colder temps.

Works well in a drag and drive car with a 427 ls in it. Was very impressed with it starting so well. Very lightweight, small and cheap.
