Long cycle life Deep Cycle Battery with WIFI function

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.
