How to Custom Battery Packs

1 Application  

People want to keep secret for their new project, but this is not good for custom battery project, as there are many battery chemistries, and the battery engineer knows what fit best for your design.

If you don’t want to let us know, you can at least tell us what it is in general, like a speaker, health tracker, detector.

below are some examples:

A Cylindrical Battery of 18650 Battery Cell and 26650

18650 is the top Choice whenever you have lithium battery requirement, the TOP 1 reason is you don’t have to wait and you only need a small MOQ for your order.

Application: Ultrasound devices, Drug delivery systems, Patient monitors, Imaging systems: popular brands like Spectrum Imaging;ACD Systems;Orbital Atk;ECRM;Sirona;Nexus Publications, medical/hospital cart, Ventilators, Defibrillators: Advanced Life Support (ALS), Automated External Defibrillators (AED), Implantable Cardioverter Defibrillators and Implantable Cardioverter Defibrillators (ICDs), Surgical tools: includes ENT Instruments Haemostatic Forceps Diagnostic Instruments Home Surgical Kit Anesthesia, Motorized wheelchairs, Medical UPS Systems

Important takeaway: Always consider first of the cylindrical battery for your project, as they have a large stock in the market, it can really get your product into mass production much faster.

Lithium Polymer Battery CellLike 487878 750545

for 487878 like above picture, it’s 4.8mm(Thickness)*78mm(Width)*78mm(Height), and you can calculate the capacity with its Volume times Ratio(0.09-0.13) like above 4.8*78*78*0.115=3400mAh

Remember the Ratio is changing regarding the volume but generally, you can treat it 0.11-0.12


A). Portable Equipment:
Post machine, handset, portable printer, data terminal;
B). Medical Instruments:
Ecg monitoring instrument, ultrasonic, breath machine, electrocardiograph
C). Industrial instrument and communication instrument:
Flaw detector, fusion splicer, optical power meter, gas detector
D). Consumer Electronics:
PDA, MID, PC, POS machine, electric tool, laptop. Ebike, emergency light power, data camera, DV, speaker, mp3, mp4 portable DVD and so on.
E). Portable Equipment:
POS, Portable printer, handset. Electric toy: RC car/ boat/helicopter etc.

Important:  provide with a max dimension of your battery and ask your vendor for an off-the-shelf model of lipo battery, this can help your project start much faster, this is really important if you just want to start with a test of the market.

Application: EV(Electric vehicle), E-bike, E-motorbike, Rickshaw, Yacht, UPS System, Energy storage system, Mobile Tower Station, etc.

Battery Cell Different in Size, Energy Density, and Performance

2 Decide the Working Current and Peak Current

Working Current/ Constant Current means the current the device draws in general, if you don’t have an engineer to know about it, let us know the watt of the device.

Peak Current also called Max current  which is mostly used to describe current that may happen in seconds when  device just start and may have a high drain current requirement(normally seen when there is motor inside)

3 Decide Working hours of the Battery

It’s really important that you let us know the capacity of the battery you want to make. Battery capacity is measured in wh or mAh.

Working hours are very important as that will decide the battery pricing, as well as battery size.

4 Decide Size Requirement

In some cases that you might have already wanted the battery to be in-house, let us know what room is left for the battery

POS Machine and it’s Battery

5 Choose Battery Casing:

There are mainly 3 types of outer casing: PVC, Plastic casing, metal casing

6 Select Connector Type

Popular types like JST, JSH.

Part of Lipo Battery Pack connectors

Others like 55*25 type

7 Check the Quantity

Quantity does influence the product price, even if you don’t know, it’s better to simply ask for a range.

How to Custom Battery Packs

Q: Who will do the CAD?

A: We prefer that you can send us CAD design, but we can do that if you require us to do so.Prototypes of the battery pack are provided for your final review and approval.

Q: What type of Cells will you use for my Battery Pack?

A:  This will depend on your project, the different project will require different cells, like lipo or lifepo4, we focus on lithium technology.

Q: How Can you Ensure that you are the Lowest Prices on the Market?

A: We promise that we are the lowest on the custom battery pack market, oh, did I say that we are the lowest, well, scratch that, we cannot be the lowest, you can always find a lower price out there. But the truth is: you will not choose the lowest, don’t you?

Q: Did you sell to the USA, Did you sell to Europe?

A:  Yes, and we even have local dealers, just drop for inquiries.

Q: I know nothing about the battery, can you help me with my design?

A: Life is tough, especially when comes to battery, but you got DNK, we are one stop solution provider for all your lithium battery pack needs, drop us an email and let’s talk details.

Q: My batteries need waterproof and ***?

A: WTF, why not contact us to see if we can make it, just leave us messages.
