LI-ION 18650 BATTERY – Lithium Polymer Batteries Manufacture

The Li-ion 18650 battery offers the best performance of any consumer-grade rechargeable battery. They’re not susceptible to damage from charging before being fully discharged (as was the case with the old nickel cadmium cells), though they’ll degrade at about the same rate as your smartphone battery.

The Li-ion 18650 battery isn’t a standardized cell. They’re not all built equally, or with the same task in mind. The most important trait to consider when looking at Li-ion 18650 battery is the continuous discharge rating (CDR), also known as amperage capacity.

The most important trait to consider when looking at Li-ion 18650 Batteries is the continuous discharge rating (CDR), also known as amperage capacity.

The CDR is the rate at which current—measured in amps (A)—can be pulled from the battery without it overheating. In order to find out which battery is right for you, you’ll need to match the CDR of the battery with the power draw associated with your device.

If you pick the wrong battery, the cells will get too hot. The heat will damage the 18650 battery, reducing its overall lifespan. Overheating may even cause the cells to explode, leak, or damage your device.

The connector made by JST Molex Hirose is also available with the custom length of wires.PCM can built-in for over-charging, over discharge, short-circuit and temperature control.

LiPol Battery is a good LiPol battery supplier known the battery industrial over for quality safety, price and lead time. Wearable Medical Solutions Hardware Industrial Solutions Wireless Communications Solutions.
