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.

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℃.

Regarding to Polinovel the 12V lifepo4 batteries' IP :HD series: IP65; N and Novel series: IP66.If you want a higher waterproof IP level, we are very pleasure to provide you. Please let me know what's your requirement.

Analog Car Vibration Test

To ensure the safety of our lithium batteries, we not only had many electric tests, but also had a series of environment tests, including the Analog Car Vibration Test below.

Q2.: Can we do series and parallel connection by ourselves (12 volt battery)?

A2.: Yes. But, we should pay attention to below tips:

a.: Connect the same spec. battery pack. Please don't mix them.

b.: The voltage difference of the connection batteries should be 50mV below.

c.: Support 4 series OR 4 parallel connection. Please don't do series and parallel connection at the same time.

d. If we don't obey the tips, It may cause battery damaged or shorten the battery lifespan.
