Li-Pol batteries
Lithium-polymer batteries, thanks to the gel electrolyte, do not pose the risk of spillage . It is also easier to create any shapes tailored to the devices in which they are to be powered. Lithium polymer batteries are currently used in most mobile phones (and other portable devices) - they are the successor to the previously used NiMH batteries (nickel-metal hydride batteries). Li-Pol packages, compared to NiMH batteries of approximate size and weight, offer approximately twice the current capacity , and are more durable and more resistant to difficult external conditions.
What should you remember when purchasing and handling Li-Pol batteries?
Lithium polymer batteries require proper treatment to remain fully functional. One of the most important factors is the moment and method of charging and discharging the package. A single cell should not exceed a certain discharge value (3V) because it may be permanently damaged. In the case of packs (batteries with a larger number of cells), you need to control the discharge of each of them separately - for this purpose, you should use balancers that allow you to control the voltage on each cell separately (separate outputs for each cell). To ensure appropriate operating conditions for this type of batteries, you should use appropriate chargers with a special logic system, which most often charges the cells through the balancer socket (it ensures uniform charging of each cell in the pack). The battery is charged at the maximum current and increasing voltage, and when the maximum level is reached, the current is reduced (the maximum voltage on the battery does not mean it is fully charged). Li-Pol battery chargers are divided into mains and special modules .
What will you find in our electronics assortment?
Our offer includes packages with 1, 2, 3 or 4 cells (cells) . The output voltages are 3.7 V, 5.0 V, 7.4 V, 11.1 or 14.8 V (depending on the package), while the capacities depend on the size of the cells - 110 mAh, 150 mAh, 220 mAh, 250 mAh, 300 mAh, 320 mAh, 400 mAh, 450 mAh, 470 mAh, 500 mAh, 520 mAh, 550 mAh, 560 mAh, 600 mAh, 650 mAh, 700 mAh, 750 mAh, 800 mAh , 850 mAh, 900 mAh, 980 mAh, 1000 mAh, 1100 mAh, 1200 mAh, 1250 mAh, 1300 mAh, 1350 mAh, 1400 mAh, 1500 mAh, 1550 mAh, 1600 mAh, 1800 mAh, 2200 mAh, 23 00 mAh, 2500 mAh, 2600 mAh, 2700 mAh, 3000 mAh, 3200 mAh, 3300 mAh, 4000 mAh, 4400 mAh, 5000 mAh, 5200 mAh, 5300 mAh, 6000 mAh, 8000 mAh or 12000 mAh. Greater capacity is also associated with larger dimensions and weight of the battery - it ranges from 5 g to 415 g. Other dimensions also depend on the model: length is from 25 mm to 172 mm, height from 3 mm to 42 mm, and width from 11mm to 80mm. Manufacturers who make the batteries we offer include Akyga, Cellevia, Dualsky, Gens Ace, Goobay, GPX Extreme, Pi Supply, Redox and Tattu.
