Polinovel lithiumbattery life cycle— 1C charge and discharge
The test results show thatPolinovellithiumbattery 100% DOD, the life cycle >2000 times, with only DOD50%, the life cycle can reach 6000times.Compare with thePolinovel lithiumbattery life cycle, the lead-acid battery is just 400-500 cycles. Cycle life is greatly affected by higher levels of discharge in lead-acid, versus only slightly affected inPolinovellithium-ion batteries.
To approve the safety of our lifepo4 batteries, we had a series of environmental tests. The battery pack is penetrated by two nails, after 6 minutes, there is no fire, no explosionduring the whole testing process. Thestablechemistry of the lifepo4 batteryproofs to be outstandingsafefor useeven in an extremely tough operatingenvironment.
