About this item
- Item Dimensions: LxWxH=13 x 6.77 x 8.48 inches.
- 10 YEAR WARRANTY: As the No.1 lead acid battery brand on Amazon, Weize newest Lithium Iron Phosphate Batteries are confidently guaranteed for 10 years! We aim for quality followed up with quality customer service, Amazon doesn't deal with the return of battery-related products, so please contact the seller directly. Weize support team is on standby for YOU.
- BUILT TO LAST: Our 12V 100Ah 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 5 times longer than a lead-acid battery, which actually reduces overall cost. It has cold weather protection which is critical.
- AUTOMATIC BMS AND LOW TEMPERATURE CUT-OFF : 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). Besides, charging low temperature cut-off function will cut off the battery when the temperature below 32°F to ensure safe use and battery performance.
- 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. Please charge the battery with a dedicated LITHIUM BATTERY CHARGER, and no more than 4 batteries in series or parallel.
- SAFE AND ENVIRONMENTALLY FRIENDLY: 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. BUT please read the user manual carefully before using, don't hesitate to call us if you have any questions about the battery.

TROUBLESHOOTING
- Can not discharge
1.Check whether the battery is securely connected.
2.Check whether the positive and negative battery terminals are correctly connected.
3.Check whether the battery voltage is greater than 12V. If it is less than 12V, charge the battery first.
4.Check whether the load voltage matches the battery.
5.Check whether the load current is greater than 100A, ensure it is less than 100A.
6.Ensure that the ambient discharge temperature ranges from -15°C to +55°C.
- Can not charge
1. Check whether the battery is securely connected.
2. Check whether the positive and negative battery terminals are correctly connected.
3. Check the charging voltage matches the battery , the charging parameters are set correctly.
4. Check whether the charging current is greater than 100A and ensure that it is less than 100A.
5. Check whether the battery voltage is less than 9V. If it is less than 9V, use the charger with 0V charging function to charge.
6. Ensure the charging environment temperature ranges from 0°C to +45°C.
7. After the battery is protected by over-discharge, disconnect the load and wait for the battery to recover the voltage before charging, or use the charger with 0V charging function to charge.
- Battery heats up
1. Check whether the battery is securely connected. The connecting wire should be in contact with the battery terminal. Do not clamp screws to discharge.
2. Check whether the battery cable matches the working current. 6AWG or 4AWG cable is recommended.
3. Check whether the load power exceeds the battery discharge power of 1280 Watt, ensure the load power is lower than the required battery power.
4. Ensure the working temperature is lower than 55 °C.

The batteries have been in use for less than a month, but they are working exactly as expected. If there are any updates, I will post them here.
Advice for purchasing LiFePO4 batteries:
Upon receiving the battery, use a LiFePO4 charger (not LA charger) to charge before use.
Do not put into service for a least an hour after removing from charger.
If planning parallel installation, balance the battery bank for 24 hrs prior to putting into service.
Watch for swelling during the first day or so after putting into service.
Follow the seller's instructions if you have a problem with the battery, it was a painless experience for us.
Life is never perfect, accept this and move on.

Only 1 speck of anything close to a complaint was I lost my 2 plastic covers that go over the terminals for shipping, I’m sure 99% of folks throw them away anyway. Although their CS was good about talking with me they wanted $15 for 2 more. They’re not .25 worth of plastic, they could have sent me 2 for nearly nothing but oh well, like I said I accidentally threw them away so it was my fault.
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 loads
STARTING-is just that, for starting
Want both? Get a Dual Purpose.
I bought the wrong type of battery, and Weize accepted the return. Cudos to them.
