Production & Test

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 as bumps, 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

Polinovel high 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 work normally, and fish is alive, No electric 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.The stable chemistry of lifepo4 battery proofs to be outstanding safe for use even in extremely tough operating environment.


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.

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.

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.

Certificate Time:

CE -----  2 weeks          MSDS ----- 1 weeks           UN38.3 ----- 4 weeks         UL/IEC ----- 10 weeks

Certificate Cost:
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.

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. Does Polinovel battery include BMS? Can we use it for vehicle?
A4: 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 . If you want to use standard vehicle, please inform us, we need to adopt more complex design BMS and different technology solution.
