## Features

- ✅ Self-Heating Function: The intelligent self-heating function will start operating automatically once the battery temperature is lower than 0°C, the external charger voltage is greater than 14.2V and the charging current is greater than 3A. Whether you are a winter camping enthusiast or a self-sufficient boat or cottage owner, the WEIZE SELF HEATING battery has been designed to effortlessly keeping your battery charged in cold environments.
- ✅ BUILT TO LAST: Our 12v 200ah self heating LiFePO4 batteries live more than 2000 cycles at 100%/8000 cycles at 50%(Suggested) depth of discharge, without decreasing in performance. The average lifetime of lead-acid batteries is about two years(500 cycles) at just 50% discharge. This basically means a LiFePO4 battery will last you at least 3 times longer than a lead-acid battery, which actually reduces overall cost. It has cold weather protection which is critical.
- ✅ Built-In 100A BMS: The built-in Battery Management System (BMS) protects your battery from Over Charge and Discharge, Over Current, Short Circuiting, as well as Low and High Temperature for increased performance and longer life. The BMS will automatically cut off the battery and the voltage will drop below 1V. Only when the circuit is cut off, the battery will automatically reactivate after 1 second (No longer need a higher voltage input to activate).
- ✅ LIGHTWEIGHT AND VERSATILE: Compared to lead-acid batteries, lithium battery provides greater energy density and only 1/3 the weight of lead acid batteries, it is a perfect upgrade for any Deep Cycle battery, and best choice for many applications such as Fish Finders, Ice Fishing, Boating Electronics, Camping, Solar System. ✅Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series.
- ✅ SAFE AND ENVIRONMENTALLY FRIENDLY: Made from safe, nontoxic, not hazardous energy. Our LiFePO4 battery has higher chemical stability, it is not prone to thermal runaway and will not overheat or catch on fire even if punctured.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great batteries for trolling motors.
*by A***R on April 24, 2025*

Great products. Customer service helped me out with a free replacement. Bought 2 12v batteries for my trolling motor. 1 the bms kept shutting off the battery. I'd have to jump start it to get power back. Sometimes once a trip, Sometimes 4 or 5. I contacted CS and they directed me to a couple test to do. After a few back and forth they sent me a brand new replacement. Ive had these batteries since March 2023. Bought an electric jack for my camper hitch. Works great! Definitely will get a battery for my camper next. Good company that backs it's products. I don't know why other had problems with CS.

### ⭐⭐⭐⭐⭐ My 1st 100 ah LiFePO4, but amazing!
*by C***E on June 7, 2024*

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!

### ⭐⭐⭐⭐⭐ Great buy
*by M***N on April 28, 2025*

So far so good, I was using AGM batteries 130 AH and was going through the full charge in about 3 and half hours on my trolling motor 80 lbs thrust. I use anchor lock a lot, which uses GPS to hold the boat in one position no matter the direction of wind or the current is moving. The motor will hold position by speeding up and down and turn the boat accordingly.I got a great tip from a professional charter fisherman to switch over to lithium battery so I did my research and found that this battery was the best bang for the buck and had a great ratings. I don’t know why I waited so long, I can run 4 to 5 hours (same use) for 3 to 4 days before I have to charge the battery. You get Bluetooth reporting directly to your phone on the app provided by the manufacturer, I get all the rundown on the condition of my battery.
