LONGER LIFE
LiFePO4 Batteries live more than 2000 cycles at 100%/8000 cycles at 50% depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge.
AUTOMATIC BMS AND MAINTENANCE-FREE
Weize Li-iron Batteries include Battery Management System (BMS) technology that protects your battery from Over Charger and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life.Weize Li-iron Batteries include Battery Management System (BMS) technology that protects your battery from Over Charger and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life.
LIGHTWEIGHT AND VERSATILE
Compared to lead-acid batteries, lithium provides greater energy density and are at least 1/2 the mass, it is a perfect upgrade for any 12V Deep Cycle battery, and best choice for many applications such as Fish Finders, Ice Fishing, Camping, Solar System, Home Alarm Systems, E-Scooters and applications in Extreme Temperatures(Discharge Temperature -4℉ to 150℉). Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series or parallel.
SAFE AND ENVIRONMENTALLY FRIEDNLY
Made from 100% safe, nontoxic, not hazardous energy, Weize LiFePO4 battery has higher chemical stability, it is not prone to thermal runaway and will not overheat or catch on fire even if punctured. With no acid in the battery, you're able to safely mount in any position.

Impressive discharge current! The safety/protection circuitry works as advertised, and cuts off power when the voltage is low or too much current is drawn, then it resets itself. It's a little heavy, around 25lb, but it's lighter than most other battery technologies, and the handle makes it easy to carry

I haven't had this long (~5 charges) but compared to lead-acid, what a difference! This is now my 50 lb thrust trolling motor battery and I couldn't be happier. Higher end batteries of this type can be several hundreds of dollars. This one was in the $250 range. It has a 10 year warranty, which is double most, but even if it lasts 5 years, that would bring it into the same price range of a couple of lead-acid batteries. A single charge lasts significantly longer than a lead-acid battery so I no longer worry about running my motor on '5', for fear of losing power before I'm done fishing. The weight is also about half, which is important in my 12' fiberglass boat. And charging, which often wasn't complete by the next morning, with a lead-acid while on fishing trips, is complete in the middle of the night with this LiFePO4. Note that this battery type requires special charging, but most chargers, even low end ones, now have this option. While this review mainly focuses on the advantages of LiFePO4 batteries, and not this brand, I haven't had it long enough to single out brand differences. I will say though that the price of this one stands out as do warranty and how solid it appears. I'll update this review if I learn more over time.UPDATE Jan. 2, 2025:I used this battery fishing lakes all summer and on several trips in the fall. It is still performing as well as it did when I got it and I have nothing but great things to say about it. For a trolling motor, pass on buying lead-acid and go LiFePO4. If the price remains good, this brand has my strong endorcement!

Run fishfinder off this battery and it will last all day! Even on the ice the cold hasnt effected its charge at all. Cheap and reliable, well worth it

I got this battery (100Ah LiPo) to replace my 50Ah AGM deep cycle for my small inflatable with a 20HP outboard. I was unaware that a deep-cycle battery is not suitable for starting a gas motor as the 50Ah seemed to do the job. I was replacing the 50Ah since it did not have enough stored energy to run the trolling motor long enough to get my loaded boat back in an emergency.After getting the new battery I was very impressed with its lightness and appearance. After 3 boat trips and 3 months (wintertime) I realized there was a real problem with the battery. It would 'disconnect' about 50+% of the time when starting and I would have to use the pull starter - even out on the open ocean. I took my time troubleshooting and eventually came to the conclusion that I had a defective battery.I contacted customer service and they had a pleasant and helpful chat with me over the space of several days - They are most likely in Asia. End result is they felt the battery I bought was not suitable for my boat and sent me a return label even knowing that the battery being returned is most likely perfectly fine.Initially I was disbelieving, since my 50Ah AGM battery worked fine, but as I did more research I was the uninformed one. I now know that:DEEP-CYCLE is for sustained loadsSTARTING-is just that, for startingWant both? Get a Dual Purpose.I bought the wrong type of battery, and Weize accepted the return. Cudos to them.

****Update February 10 2025****I opened a ticket with Weize customer support. They responded within 24 hours and were very consistent with always replying within 1 business day throughout the process. They had me perform a number of tests, take pictures, provide additional details of the situation, provide details and documentation of the charge controllers I had tried to use.I will admit I got annoyed at how much they had me go through. However, I was outside of the warranty period so they had no obligation to help me at all. I appreciate that they worked with me when they weren't required to.My replacement unit arrived today and I tested the voltage before I even removed it from the box (which I should have done last time). It tested good and I have it hooked up to my solar installation now.I haven't had my replacement for long enough to do a full product review, but I can definitely say that Weize customer support is good. A separate customer support person even reached out to me after seeing my Amazon review to make sure I had a support ticket open.***Original review January 24 2025***I have been wanting to upgrade my solar storage from lead acid to Lithium for a while and picked this up during a sale. I knew my charge controller couldn't handle LifePo4, so I set this aside after unboxing until I could find a good deal on a new charge controller.I finally got a good deal on a Victron and started upgrading my system. That's when I stuck a Multimeter on the battery and realized it was only reading 7-8 volts. Up to this point, this battery was unused and still had the plastic caps on it, I even had to hunt down the terminal bolts as they had been "cleaned up" at some point in the previous 11 months.I figured those readings meant the battery was toast, but decided to connect it to the new charge controller (set for LifePo4 charging) and see if it would recover. After 4 days it is still only at 8 volts.Just to be sure I swapped in a 20AH 12v LifePo4 battery out of my portable power kit and it charges without issue on the new Victron.Being a LifePo4, this battery shouldn't have had any issues with sitting indoors for 11 months before being put on a charger. I'm disappointed.

Battery worked great for the first 9 months then wouldn't take a charge. The tech support had me try a force charge and repair and neither worked. i sent a video of the process to prove it wasn't taking a charge. They promptly sent me a new replacement within a week.
