No , but we can provide it after samples completed.

If customer need, the lithium battery pack can be built in BMS according to device parameter.

Normally ,the discharge current of most 3.7v lipo battery is 0.5C discharge ,but some special lipo battery has high discharge rated ,we can provide the 1C discharge lipo battery if customer need.

The discharge temperature should be between -20℃ to +60℃.

We can check the appearance of the lithium battery first ,there shall be so such defects as followings,which may adversely affect commercial value of the cell.1.Scratch2.Rust3.Discoloration4.Dirt5. Deformation 6.Leakage

The cell should not be used with other cells having a different capacity ,chemistry ,or manufacture. Doing so could cause the battery to generate heat,smoke,catch fire,or explode.

The recommendation is SOC 10～50% for long-term storage

Usually, the battery condition at shipment SOC (State Of Charge ) not exceed 30% of rated capacity

If you don’t use the battery for a long time , you should better remove the battery to dry condition of low humidity. Even though the device has been turned off , the battery still will consume some current ,it will shortens the working life of the battery.

Our MOQ for power bank is 500pcs.

Yes , we can provide if you need .

1. application 2. working voltage range 3. max continuous current and peak current 4. max battery size

After charge, tested the batteries' initial state and capacity. Charge to 10.0V at 3C current, then charge to 0.01C at CV mode.Observe changes in battery appearance.

Yes, we can produce by your samples or technical drawings.

Yes ,Alibaba is 3rd party company .Buying from Alibaba is safe, secure and simple. Alibaba offers you secure payment, guaranteed quality and guaranteed delivery.

We can provide the free Alkaline battery sample , but the customers have to pay the courier cost.

For sample , the qty should not exceed 10pcs ;Low MOQ for mass production ,at least 50pc.

The current is customized according to the load parameters provided by customers.

Yes ,we can help to find the manufactory.

No, it doesn’t built in pcm.

Usually the nominal voltage of import cell is 3.6v, this will have almost no impact on battery.

Don’t handling Lithium Battery Pack with metalwork.Do not open,dissemble,crush or bum battery .Ensure good ventilation/exhaustion at the workplace. Prevent formation of dust.lnformation about protection against explosions and fires: Keep ignition sources away-Do not smoke.

It’s depend on your order , if you place a large order , we would sent free sample to test .

Yes , we can do it according to your request.

Yes ,it can. But it belong to non-rechargeable.

Sure, we respect clients' requirements, will bring more benefit to you.

Firstly, we need to know the device, the working voltage range , the max continuous current, the peak current, the connector No.Since the more details you provided,the faster we could provide you with the corresponding products.

Yes , you can look for our product information on website ,it show all kind of dry battery information .

It takes at least 15 working days

No , actually the nimh battery pack could not add PCB.

No , we have all kinds of cells for your choice, like 32700 cell ,32650 cell ,14500cell, 18500 cell ect.

Yes , we can provide the MSDS report which issued by our company . If you need it issued by test company ,the certified fee need to be paid by your side .

-20°C~45°C, 65±20%RH storage for a long time(3 months) and the storage condition shall be:

Yes,we can paste your label on the battery.

All of ourbattery cells with Grade A,100% new and real capacity.

We mainly use Samsung, Sanyo, Sony,Panasonic and LG cells for battery packs, and also use some high quality Chinese cells which have good performance.

Usually, we need to know the device , working voltage range , max. continuous current and peak current , order quantity ,the connector module if you need .

Most 18650 batteries will last between300 and 500 charge cycles, but battery lifetime can be extended far beyondthose numbers.If charged regularly before completedischarge. All batteries degrade over time, but you’ll often get over a year ortwo of life from an 18650 depending on your use.

Yes, we candesign and produce high capacity 18650 lithium ion batteries according to client request.

Sure, we respect clients' requirements, willbring more benefit to you.
