72V Trolley/Portable Back-up Power for Outside First-Aid/Exploration/Emergency/Field Work/Travelling with 1200times Cyclelife and CE, SGS

1. LiFePO4 battery manufacturer
2. Long cycle-life, high capacity
3. Certification: CE, SGS
4. OEM services provided
5. 1200 cycle-life

Features of LiFePO4 battery:
1. High energy density, 170mAh/g
2. Light weight, about 1/3 the weight of lead-acid batteries
3. Does not contain any toxic heavy metals such as lead, cadmium, nor any corrosive acids or alkalies thus making LiFePO4 batteries the most environmentally friendly battery chemistry available
4. No memory effect, charge and discharge at any time.
5. Around 1200 discharge cycles life compared to typically around 300 for lead acid.
6. Safe and reliable, One of the safest / most forgiving / stable chemistries in the lithium family.
7. Extremely low self discharge rate, ≤ 3%(monthly)(unlike lead acid which will go flat quite quickly if left sitting for long periods).
8. Virtually flat discharge curve means maximum power available until fully discharged (no "voltage sag" as with lead acid batteries)
9. Does not suffer from "thermal runaway"
10. Can be used safely in high ambient temperatures of up to 55° C without any degradation in performance
11. High discharge rate capability, 3C continuous, 5C pulse discharge
