High density power source - 

Lithium Battery Cell 

Updated Date: 2019/11/03

To supply the significant high energy density and high C rate power to the market, Maxtela takes advantage of this emerging Li-polymer cell to go for the design of E Motor Power and create this superior value added battery sources in the specific industry. Such reliable Lithium Polymer battery power is capable best replica handbags to create high performance competing with other battery cells, safe and low risk. Battery Management System (BMS), Protection Circuit Design (PCD) and Over Heat Prevention (OHD) are available in our design of battery pack, which also enable Maxtela's E Motor Power to supply the best power quality, and make the battery pack flexible in size comparing to the regular battery pack.

New Power Source to Mobile devices

 Supercapacitor

Updated Date: 2019/11/07

The supercapacitor concept has been around for a number of years. Newer designs allow higher capacities in a smaller size. It resembles a regular capacitor, but it offers very high capacitance in a small package. Energy storage is by means of static charge rather than of an electro-chemical process that is inherent to the battery.

The amount of energy a capacitor can hold is measured in microfarads or µF. (1µF = 0.000,001 farad). While small capacitors are rated in nano-farads (1000 times smaller than 1µF) and pico-farads (1 million times smaller than 1µF), supercapacitors come in farads.

Different operation from a main battery, supercapacitors are more commonly used as memory backup to bridge short power interruptions. The charge time of a supercapacitor monster beats is about 10 seconds. The ability to absorb energy is, to a large extent, limited by the size of the charger. The charge characteristics are similar to those of an electrochemical battery. The initial charge is very rapid; the topping charge takes extra time. Provision must be made to limit the current when charging an empty supercapacitor.

Regarding to charging method, the supercapacitor resembles the lead-acid battery. Full charge occurs when a set voltage limit is reached. Unlike the electrochemical battery, the supercapacitor does not require a full-charge detection circuit. Supercapacitors take as much energy as needed. When full, they stop accepting charge. There is no danger of overcharge or 'memory'.

The supercapacitor can be virtually recharged and discharged for an unlimited number of times. However, the electrochemical battery, there is very little wear and tear influenced by cycling and the time of life does not affect the supercapacitor much. In normal use, a supercapacitor degrades to loan about 80 percent after 10 years.

 Advantages

Virtually unlimited cycle life
Low impedance  Enhances load handling when put in paralleled with a battery.
Rapid charging – Complete the charge in seconds.
Simple charge methods – Without the detection of full-charge; eliminate danger of overcharge.

Maxtela is engaging into the design of relative products, and will come out the completed products in terms of this new power source in the following year.

 

New Lineup in Maxtela's product family - 

LFP Battery Pack 

Updated Date: 2020/03/10

As customers are aware of lithium battery products more and more, in recent years, even the lithium battery products in many design applications formally have took place of NiCd, NiMh or lead acid rechargeable batteries which used in the past.

The product unit price on manufacturing cost is more attractive than the past, especially for users who expect to obtain a larger output current, lithium batteries can provide the greater discharge power in a smaller volume.

It is worth introducing that Maxtela will progressively provide our customers with lithium iron phosphate battery products relying on the well experience of battery assembly in the past and the quality requirements of famous foreign manufacturers. Currently, we are actively planning products on the shelf, including 12V standard batteries and 6V standard batteries, these two series are adopted 3.2V lithium iron phosphate battery cell as the base, and built-in PCM protection circuit board that prevent the damages causing by the error uses, including overcharge protection, over discharge protection, polarity Reverse connection protection, low voltage protection, etc.

For now, we are going to promote LFP battery pack in the market step by step, If you are interested in this kind of product, or some altenative batteries are attractive to you, please send us an email or call us for more information. However, we will love to work out the appropriated product model for you if we are not available at the moment.
