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.
Temperature Effects onPolinovel lithium battery
Most of our customer’s 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 beforeplacean order.Below testing results is about the discharge capacity of 12V 100AhPolinovelLithiumbattery pack under different temperatures.
@1C discharge, our battery remains,
75% discharge @working temperature -10℃
90% discharge @working temperature 0℃
98% discharge @working temperature 20℃
99% discharge @working temperature 40℃
Over-temperature Protection
With over-temperature protection, BMS will cut off discharge or charge when battery temperature meets 65℃.
Custom Solutions according to the working environment
Polinovel lithium battery waterproof testing
Polinovelhigh technology lithium batteries are also widely used for marine applications, like Yachts, Fishing Boats, Sailing boats, Kayak, Catamaran, etc. Most manufacturers, businesses, users are concerned about the case of the battery can be waterproof or not.
The test results show that Polinovel lithium batteries are excellent safety for waterproofing.
NailPenetrationTest
To approve the safety of ourlifepo4 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.

Q2.: Can we do series and parallel connections by ourselves (12-volt battery)?
A2.: Yes. But, we should pay attention to the 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 connections. Please don’t do series and parallel connections at the same time.
d. If we don’t obey the tips, It may cause battery damaged or shorten the battery lifespan.
Q3.: How can I resell lithium batteries well in my market?
A3.: Do market research, set your focus application field, learn more knowledge about lithium batteries. build your own brand. We can work together with you to explore the market.
Q4.: Why do Polinovel guys ask me so many questions? I just want to know the price !!
A4.: Sorry for annoying you. But the discharge current, voltage etc. Information is very important for us to produce the correct battery for you. If we produce a battery that can not achieve the real application discharge current, size etc. That will put both of us in a very embarrassing and lose-lose condition. We also have a price list, but it is only for your reference. We should confirm the discharge current etc. Information before we produce your orders.
Q5.:Does Polinovel battery include BMS? Can we use it for vehicles?
A5.: Yes, our battery pack include BMS, you can use it for low-speed vehicles. And make sure the discharge current can meet the application request (please refer to Q4). If you want to use the standard vehicle, please inform us, we need to adopt a more complex design BMS and different technology solutions.
