Experience enhanced performance and extended battery life, knowing that your Weize LiFePO4 battery is in safe hands. Plus, our BMS ensures automatic circuit cut-off, and reactivation requires no higher voltage input - hassle-free power management made easy!
Powerful and Lightweight - Unleash Versatility:
Harness the potential of lithium's greater energy density, which is at least 1/2 the mass of lead-acid batteries. Elevate your energy solutions with the perfect upgrade for any 12V Deep Cycle battery. Whether it's Fish Finders, Ice Fishing, Camping, Solar Systems, Home Alarm Systems, or E-Scooters, our LiFePO4 battery is the ultimate choice for an array of applications. Just remember to use a dedicated LITHIUM BATTERY CHARGER and avoid connecting more than 4 batteries in series or parallel.
Safety Above All - Eco-Friendly and Secure:
Our Weize LiFePO4 battery is crafted from 100% safe, non-toxic, and non-hazardous energy, boasting exceptional chemical stability. Fear no thermal runaway or overheating, even if punctured - your safety is our priority. With no acid involved, you can safely mount the battery in any position, ensuring optimal convenience.

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 watts, ensure the load power is lower than the required battery power.

4. Ensure the working temperature is lower than 55 °C.

Harley-Davidson battery

My original Harley battery was struggling to turn the high compression bike over with only 340 cold cranking amps, I put this lightweight 600 cold cranking amps battery in and wow could not believe how quickly it spun the bike over. Very happy. Just ordered another one for one of my other bikes.
