Custom made lithium ion battery packs

Custom lithium ion battery pack is popular because you are hardly to find an existing battery pack to fit into your electronic devices. The main reason are:

  1. Battery dimension. An existing battery design can’t fit in to your electric vehicle or other perfectly.
  2. Battery discharge current. Every electronics has different watt consumptions, you need a suitable custom rechargeable battery to power it toilless.
  3. You will need a special battery terminals like( xt60 connector) to connect with your device. And the wire cable lengh is also

CMX provide fully customied design on lithium ion battery and LiFeP04 batteries. Also lipo batteries. We can custom all details include, voltage, capacity, battery bms, connector terminals. We can also add battery fuel, Communication protocol( CAN, RS232,485, or BQ solutions). Beside the the wrap packs. We can also design battery casing in metal, ABS, PVC.  CMX also provide related 18650 battery charger with packs. Here is your all in one solution place.

How to make custom 18650 battery pack with CMX?

Li ion battery cell 18650 is the most popular Choice whenever you have lithium battery requirement.  We need to know basicly:

  1. What is your custom battery pack’s application. Need to know what is the product use the battery, This helps us better understand on custom features.
  2. Do you know the discharge information also charging way. Let us know to determine the BMS or protection pcb board to be applied.
  3. Where do you place the battery pack. And you need to know the dimensions about the custom 18650 battery pack. We must make sure the battery will fit in exactly in your space.
  4. Any other information you want us to know will be much you want gauge battery or with battery meter.
  5. If you have a prefered brand 18650 cell to be used in your custom battery pack? If so, tells us the model NO.

If the Dimensions no problem. Consider cylindrical batteries like 18650 , 26650, These most standard battery is available anytime. They can meet custom different small or big battery capacity. as they have a large stock in the market, it can really get your product into mass production much faster.

Applications of  custom 18650 battery pack :

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. Electric bike battery.

Lithium Polymer battery in Parallel and in seires.

Voltage – The pack’s rated voltage is determined by the number of lipo cells placed in series. Instead of indicating the voltage, packs will sometimes indicate the number of cells in series (indicated by #S, where # is the number of cells in series). To determine the voltage of these battery pack, you multiple the number of cells in series by the cell voltage (3.7v).

1S = 3.7V
2S = 7.4V
3S = 11.1V
4S = 14.8V

Capacity – The battery capacity is based on two things. The first is the capacity of a single cell, and second, how many blocks are placed in parallel (indicated on some packs as #P, where # is the # of parallel blocks). The reason we refer to these in blocks is because in order to double the capacity of a pack, the total number of cells cells must be double. On a 1S pack (single cell in series), a cell placed in parallel will the double the capacity. However, to double the capacity of a 2S pack, a 2S block must be placed in parallel with the existing block (Figure 3). Some examples:

1s2p = 2 cell (single cell voltage, twice the capacity)
2s1p = 2 cell (twice the voltage, single cell capacity)
2s3p = 6 cell (twice the voltage, three times the capacity)

Lithium Polymer Battery Cell like LP103450 LP803860

LP103450 2000mah

Lipo battery LP103450 2000mah

706090 3.7v

lithium polymer LP706090

LP902550 3.7v

lipo cell LP902550 3.7v

For example: Our model 103450 like above picture, it’s 10mm(Thickness)*34mm(Width)*50mm(Height), and you can calculate the capacity with its Volume times Ratio(0.09-0.13) like above 10*34*50*0.115=1955mAh. So, we can offer 2 different model. 1 with 2000mah, another with 1800mah.

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

Let’s know the 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 want make your project going smooth and not let the battery delays your project.

Why USE A LiFePo4 as custom lithium battery packs

  • LiFePO4 batteries include advanced protection-circuit-modules (PCM) that confer overcharge, over-discharge and short circuit protection ,etc.
  • High energy density: Triple of lead-acid battery and twice of nickel battery.
  • Wide range of operating temperature: charging temperature 0℃~45℃; discharging temperature -20℃~65℃.
  • Good charging retention: batteries can be stored for long period with high residual capacity, because of low self-discharge.
  • High rate discharging: the battery can keep discharging under 10C rate and its instant pulse discharge is over 20C.
  • Good security: more safe than common lithium ion battery and lithium polymer battery.
  • No memory effect: there is no need to discharge the battery before charging.
  • Long cycle life: more than 3000 cycles.
  • Environmental friendly: No cadmium, lead or mercury are added.
  • Low cost: Fe and phosphoric acid are common components in the earth.

Working Current and Peak Current

Working Current/ Constant Discharge 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 pulse current or 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)

Expected 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 mAh or Ah.

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

Dimensions or Size Requirement

Just make sure the custom lithium ion battery packs will fit in your devices or applications. 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
