12V 125Ah LiFePO4 Auto Start Battery with WIFI function
1. LiFePO4 Auto Start Battery 12.8V 125Ah advantage
- Extremely safe and stable chemistry: PCB and/or BMS built inside to balance protect the battery.
- Long life-cycle: Can be circularly used, best can up to 2000 times recycles, 8 times of Lead acid battery.
- Lighter weight, with the best power-to-weight ratio: 1/3 of Lead acid battery weight.
- Good performance at high temperature and high temperature resistance
- Low self-discharge rate, less than 3% monthly.
- No memory effects and highly efficient charge.
- Environment friendly: Clean and Green energy poses no pollution on our environment.
