WEIZE12V 105AH Dual Purpose LiFePO4 Lithium Battery, 1000CCA Group 31 Group 27 GC2 Starter Battery Plus Deep Cycle Performance, Built-in Smart BMS, Perfect for Automotive, Trolling Motor, Marine, RV

Awesome battery! For my boat and trolling motor: 12’ V nose with 9.9 Evinrude. Came 90% charged, fast with FedEx. Very light weight compared to the typical marine batteries I have had in the past, and important in a smaller boat like mine. It would be a perfect fit for my Subaru Crosstrek, but I’m sure the dealer would make an issue out of it. Maybe later once out of factory warranty :)

I bought this battery for my boat to use to start and run accessories (radio). Truly dual purpose use and instead of a 2nd battery for backup I bought a cheap portable jumpstart battery. This battery also powered my 65" TV with an inverter for a day when our power was out. I have only used it twice. Other than that, I have intermittently put it on a dedicated charger to keep it topped up. I have carried it from its charger location twice where it is inside. The 2nd time I moved it, lifting by the handle pulled the whole top off. It was a week past the return window at that time. I can glue the lid back on I suppose, but it is a shame that such a nice (and expensive) battery still works well but structurally fell apart.11-25-2024 Update. Seller offered to help repair with glue. Had no luck, but upgraded by one star given good customer service.12-6-2024 Update. Seller offered full refund or a replacement battery. They also asked that I try a different glue. Shame to scrap a $300 battery. I don't think the glue they recommended would have worked, so I bought my own glue and it worked marvelously well. I upgraded to 5 stars because of their offer for a full refund or a replacement that would not be available for 2 months, but really I think a 5 star product should show up and work without the need to fix it.

1. This battery was bought to replace my S65D26R Panasonic OEM battery in my 2012 Toyota Camry Hybrid, as a Group 24/35/47 battery, its size fits nicely in battery compartment of my trunk.2. Most Sealed Lead Acid and AGM batteries have [+]terminal on the right, [-] terminal on the left, my Panasonic OEM battery is the opposite, [+] terminal is on the left, which is rare on the market; this LiFePO4 battery matches with the polarity orientation of my Panasonic battery so that it fits right in without adding extra adapters tediously.3. After carefully connecting a back-up battery to OBD-2 memory saver hooked up with OBD-2 port underneath the steering wheel then replaced the battery, the new battery kicked in and car engine was started flawlessly.4. Although slightly more expensive than AGM batteries and a lot more expensive than most SLA batteries, it is worth the money as it has 10-year warranty and virtually maintenance free, unpredictable factors do exist, though, such as owner's driving habit.5. I did take a photo of the newly installed battery, unfortunately the format of my smartphone is incompatible and not accepted by this Amazon product review screen web page.

Has worked great for 6 months. Hoping it lasts 6 years!

800 CCA and the light weight of LiFePO4, for the same price and exactly the same size as an H5 (Group 47) AGM platinum battery (which could only deliver 680 CCA). The only minor issue is that the OEM battery cables in a Fiat 500 are slightly too short for the location of these battery lugs — but the terminals are in the correct orientation at least. That’s easy enough to fix with some tinned copper cable, tinned butt connectors, and new battery terminals, to extend them a few inches. Plus adhesive lined heat shrink tubing and Tesa tape to protect the cable extensions. Anyone driving a Fiat or similar FCA / Stellantis vehicle with extremely limited space under the hood should consider this. Weize is a decent enough brand (according to Will Prowse), but I hope other lithium battery manufacturers adopt this small battery size for their cranking / dual-purpose batteries as well.

Expensive Mistake. Worked well for 3 weeks and then would no longer take a charge. Suspect that the BMS failed or is stuck. Only holding 2.92 volts even though on a forced 14.5V charge from a LiFePo4 charger. All methods in the owners manual failed to restart BMS. Too bad because the idea is great even though in practice it is not well executed. Maybe a BMS reset button on the exterior would be a worthwhile future feature?

Works great, BMS App is xiaoxiangelectric

Great battery works well Thanks
