Polinovel lithium battery life cycle   --- 1C charge and discharge



The test results show that,  Polinovel lithium battery 100% DOD,  the life cycle >2000 times,  with only DOD50%, the life cycle can reach 6000 times. Compare with the Polinovel lithium battery life cycle , lead acid battery just to 400-500 cycles . Cycle life is greatly affected by higher levels of discharge in lead acid, versus only slightly affected in Polinovel lithium-ion batteries.

Conformity of 220pc battery cells connected in series   --- 1C charge and discharge



Temperature Effects on Polinovel lithium battery

Most of our customers concerns about the working temperature of our batteries,

sometimes, even we know that the common working temperature of different chemistry lithium batteries, they still hope to confirm with the supplier before place an order.Below testing results is about the discharge capacity of 12V 100Ah Polinovel Lithium battery pack under different temperature.


@1C discharge, our battery remains,

   75% discharge @working temperature -10℃

   90% discharge @working temperature 0℃

   98% discharge @working temperture 20℃

   99% discharge @working temperature 40℃


Over-temperature Protection


With over temperature protection, BMS will cut off discharge or charge when battery temperature meet 65℃.
