HOW IS QUALITY & PRODUCTION GUARANTEED ? Check out our advanced production facilities and testing facilities .
Polinovel provide both battery cells and battery packs, with the most advance production technology and the highest quality components, to make our lithium batteries unlike others in the market.Polinovel strictly follow the high-standard production and testing processes, to guarantee lithium batteries are qualified and safe for use in different applications.
Analog Car Vibration Test of Lithium Battery
Analog the damage caused by bumps in the transportation process,to make sure the resistance of lithium battery for environmental vibrations.
Analog Lithium Battery encountered different road conditions such asbumps, uphills, downhills, turns, sharp turn, etc.Polinovel Lithium Battery is suited to all the above road conditions, not only with stable performance, but also safe and secure.
Waterproof test on lithium battery
Polinovelhigh technology lithium batteries are widely used in marine, like the Yachts, Fishing Boats, Sailing boats, Kayak, Catamaran, etc. People may concern if the batteries are safe enough to operate on my vehicles.Below is a waterproof testing of lithium battery for reference:
Put the batteries in the sink, fill with water and put some fish in.
Multimeter measuring battery voltage and current, battery worknormally, and fish is alive, Noelectric leakage. Polinovel high technology including special processing on lithium battery production crafts to meet the requirements of IP standard in different installation and operating environment. If you want waterproof lithium battery, we are very pleasure to provide you, please let us know your requirements.
Nail Penetration Test:
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 explosion during the whole testing process.Thestablechemistry of lifepo4 batteryproofs to be outstandingsafefor useeven inextremely tough operatingenvironment.
Temperature Effects on LiFePo4
@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℃
With over temperature protection, BMS will cut off discharge or charge when battery temperature meet 65℃.
Custom Solutionsaccording to working enviroment

We have a lot of standard batteries for replacement of lead acid batteries, meanwhile, we also accept OEM/ODM orders. Please feel free to contact us, no matter you are looking for a professional battery solution for your products, or you are just thinking about to know more about lithium battery.
POLINOVEL TAKE SAFETY SERIOUSLY
We strive to produce and provide the safest lithium battery to customers. Our lithium battery have been rigorously tested and certified to be safely used in wide applications around the world.
SAFE FOR TRANSPORTATION
Recently, all lithium batteries are required to pass UN38.3 for shipment. We are proud of our batteries are conform to UN38.3 shipping regulations that are safe for air or sea shipping.
APPLY FOR CERTIFICATIONS
Polinovel can also cooperate to help applying for other safety relevant certifications to meet the market demand as per customer’s request.Like CE, MSDS, UL, IEC etc.
CE —– 2 weeks MSDS—– 1 weeks UN38.3—– 4 weeks UL/IEC—– 10 weeks
This contains two costs – Sample & Testing. Both of them are charged basing on exact battery specification. You are welcome to inform us the battery model you are interested for quoting.
First-class R&D team: Our R&D colleagues are from the TOP3 Lithium battery companies in China. we have very rich experience in lithium battery design, electronics, system testing and real application. Our R&D manager, Mr.Yan is the visiting professor of Shenzhen Technology College, we keep close communication with famous university and scientific institution. We promise to offer you a professional and high cost-effective battery solution for you.
Strict Quality Control: We set a series strict QC standards include battery battery appearance, package, internal structure,charge / discharge performance, IP request etc. We strictly obey this standards to make sure every customers can get high quality battery from us.
Customer first culture: 80% of our customers are 5 years above close win-win cooperation partner. We treat our customers as our friends, family members. Every batteries we produced, sold are priceless trust from customers, so we cherish it and we keep a grateful, royalty and honesty heart to our customers.
Polinovel Target Market:
1. 12 volt standard lithium battery.
2. Golf cart, AGV, forklift, boat, etc.low speed mobility battery.
3. Energy storage field (battery unit capacity: 50kwh below).
Q & A:
Q1.: Does Polinovel support door to door shipping? drop ship ?
A1.: Yes. Normally if the unit weight of the lithium battery is below 30kg, we can arrange DHL,UPS,FedEx to delivery it to the destination address.(Kindly note: Lithium battery freight fee is a little bit higher than normal product) . If the unit weight of the lithium battery is higher than 30kg, we can arrange the sea shipping and then arrange our shipping partner in your country to ship it to the destination address. If you are a company, we suggest you buy a small mass production order to ship it via sea. The unit import cost will be much lower than air shipping way. We support drop ship.
Q2.: Can we do series and parallel connection by ourselves (12 volt battery)?
A2.: Yes. As lithium battery is different from lead acid batteries,we should pay attention to below tips:
a.: Connect the same spec. battery pack. 12v 100ah with 12v 100ah; 12v 300ah with 12v 300ah. Please don’t mix them.
b.: The voltage difference of the connection batteries should be 50mV below.
c.: Our battery support 4 series connection OR 4 parallel connection. Please don’t 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.
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 battery industry. build your own brand. We can work together to explode the market.
Q4.: Why Polinovel guys ask me so many questions? I just want to know the price !!
A4.: Sorry for annoying you. But the discharge current, voltage and application etc. Information is the key for us to produce the correct battery for you. Lithium battery is different from lead acid battery. We can not just compare the capacity and quote. Take 12v 100ah for example, if the discharge current is different, the cost is different even the same capacity and voltage. And if we produce the battery which can not achieve the real application discharge current, size etc. That will cause both of us in a very embarrassing and lose-lose condition. We also have price list, but it is 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 vehicle?
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 standard vehicle, please inform us, we need to adopt more complex design BMS and different technology solution.
Q6. What is your warranty?
A6: Our standard warranty is 2 years. Our battery lifespan can be used for at least 8 years for normal 1 cycles per day. We have a complete warranty policy documents, please feel free to contact us to get it.
Your inquiries or questions are welcome, we will response to it quickly !
