1. Built-in large-capacity polymer lithium battery, large capacity, extremely safe charging and discharging, no burning, no explosion
2. More than 1000 charge and discharge cycles
3. Work properly at -20 ℃ - +50 ℃??.
4. High performance, no pollution, green and environmental protection
5. Self-discharge small: at room temperature for one month, self-discharge less than 5%.
6. With DC 5, 12, 24V output, AC 110V/220V output.
7. It has cascading output function, which can realize automatic switching between main and auxiliary power sources, and extend the power supply time through multi-stage cascading.
8. Large size LCD screen, eye-catching display voltage, current and other parameters.
9. AC pure sine wave output with strong load capacity.
10. It has automatic protection functions such as overcharge, over discharge, overload, overheat and short circuit.
11. Smaller, lighter and stronger: the battery of the same capacity is 50% less than the weight of lead acid. Under the same load-bearing capacity, the floor space is only about 30% of the lead-acid battery.
12. Configure a special backpack, easy to carry.
13. The battery capacity retention rate stored for 12 months is ≥80.
14. The battery itself protection level: IP56.
