Usually, these chargers can be used to charge not just LiPo batteries but also other battery chemistries. How to best maintain your battery in order to have maximum performance and life span. In other words, it means how long your device can run until the charge finishes. There is one thing that people should be careful about - when you receive your battery, if you want to charge it at rates over 2C, make sure you KNOW for a fact that the battery CAN handle more than 2C charge rates, otherwise you run the risk of ruining it very quickly, or even making it to explode. And, through consistent voltage supply, we enjoy the best performance in use. And this is how it works - all batteries have a "C" charge rate, in addition to the "C" discharge rate. Answer: Yes. When a LiPo is punctured, the lithium reacts with the humidity in the atmosphere and heats up the battery. But it should never be fully charged or discharged. RC LiPo batteries have high discharge rates to power the most demanding electric motors. Because itll determine the discharge rate you should have in your batteries. LiPo batteries run a risk of catching fire when not properly charged. Usually, A battery with 5000mah means its charging rate should not be faster than 5A. Always keep a Class D fire extinguisher nearby your battery charging/discharging and storage area. We also participate in programs from eBay, CJ, Clickbank, ShareASale, and other sites. Answer: Yes. Most batteries have a charge C rate between 2C and 5C. 100% use of power, or "Burst power" should only be reserved for a maximum of around 15 seconds, for best practice. Make sure to check it out before purchasing new cells. However, if you want to depuff a lipo battery, discharging is very important. But when we heat the batteries up during a run, or discharge them lower than 3.0 volts per cell, or physically damage them in any way, or allow water to enter the batteries (inside the foil wrapping), it reduces the life of the battery, and hastens the buildup of Li2O. Using aLow voltage buzzerwith voltage indicator like the one shown on the left is a good way to keep the Lipo above the discharge limit. Trying to do the opposite - to limit motor power by using a lower discharge rate battery - will end upover-stressingyour battery, it will puff up, and it will last only a few cycles. Lithium-polymer batteries offer many electric advantages. C rate is the battery's maximumSAFEcontinuous discharge rate. The use of adaptors like the one shown on the left gives you the ability to either use them on different setups or also for charge/discharge purpose. These cells have very stable performance in extreme temperatures, along with the higher discharge rate. Cells in LiPo batteries are denoted by S. Please ensure you only use these(or any other Lithium Ion) batteries with proper Lithium Ion chargers and equipment. Dispose of the battery in the trash. We have a quick suggestion for the best LiPo batteries. For long term storage, the batteries should be discharged or charged, depending on their current state, to around 3.8v per cell. 1 x Polymer Lithium Ion Battery, with cable and JST connector, not to charge or discharge at higher currents or voltages, [mx_insert-post-ebay slug="ebay-t-default"], Polymer Lithium Ion High Discharge Batteries, * Many smaller items on our site qualify for. 2.

Lithium Polymer batteries (henceforth referred to as LiPo batteries), are a newer type of battery now used in many consumer electronics devices. This is how the battery industry has decided to discuss and compare batteries. These are the capacity and voltage of the battery. This meant that there were actually four cells in the battery; two cells wired in series, and two more wired into the first two batteries in parallel (parallel meaning the capacities get added together). These are few salient features of Melasta high discharge LiPO Cells, 1. These batteries are means for devices that require high currents, like RC cars, planes, drones, helicopters and similar. The unit of measure here is milliamp hours (mAh). The discharge rate is the current value required when the battery discharges its rated capacity within a specified time. We hope your concept has been crystal clear by now. Express posted from Sydney. A standard connector gives advantage of charging and having the ability to swap batteries between different vehicles. Their overall life span is comparatively much shorter (about 500-800 charge cycles), especially when used in high demand applications, ie, high discharge lipo battery . Irrespective of the battery's voltage (cell count), C rating, or capacity. These are only a few of the guidelines, and warnings that any user of LiPo batteries must keep in mind. No, its highly discouraged to leave it discharged for many days. Because a battery with more cells provides a higher voltage.

Combining the high ratewith the lithium polymer battery, the lithium polymer powerbattery with a large discharge C number is a high C-rate battery, which generally does not apply to digital products such as mobile phones, but is used in those needs. You can do this a number of ways. High Rate Discharge C rating means how quickly a lipo battery can be discharged. As long as the voltage is 3.8v per cell, the Lipos should be OK to sit for a long period. If your wires are very thick (larger than 12awg) then they are really tricky. Discharge the LiPo battery as far down as you safely can. We also share information about your use of our site with our social media, advertising and analytics partners. Always pack your LiPo batteries in your carry-on bag and never in your checked baggage when traveling on an airplane. It is not, however, the full charge voltage of the cell. 78.47.192.213 Some brands also use Amp ratings, which is pretty much the same, just a different scale, so 2200mAh will be displayed as 2.2. GenX Power Premium Lithium Polymer Batteries are known for the high performance in professional applications. Mix table salt into some warm (not hot) water. If you are drawing 5A from a 2000mAh pack, simply take the current and divide by the capacity: 5A = 5000mA, 5000mA / 2000mAh = 2.5C. That is only the theory however, in reality, some of the cheaper battery brands tend to over-rate their batteries, which causes a lot of people a lot of frustration, and dramatically reduces the battery's life span. While they come with useful safeguards, the user of the battery is ultimately the one responsible for making sure that everything is above-board and proper. An example of data being processed may be a unique identifier stored in a cookie. We will confirm with you on the main parameters of the LiPo battery, such as the dimensions, capacity, cables, connectors,discharge current. Check out our Privacy Policy. Those are the Lipo alarms that display battery pack and cell voltage on a screen, and have a button for adjusting the alarm voltage. Sometimes performance is equivalent to the voltage it consumes. Specification. We need connectors that meet several needs including how well it allows current to flow, how easy the connector is to solder and use, and of course there are safety concerns as well.

RC LiPo batteries have large capacities, meaning they hold lots of energy in a small package. If you select the inequality High rate discharge LiPo batteries, it may lead to short-circuiting of LiPo Batteries and even have destroyed to your devices. LiPo batteries do not work well in cold weather. 3. These are very powerful batteries, and extreme care should be taken using them. ~ 3.7 to 3.9 Volts per cell for storage is the optimum one. Never fill the container to capacity with your batteries, always follow manufacturer recommendations on LiPo bags for how many mAhs it can safely contain. So, its better to keep at least 50% of the charge. As itll be able to perfectly tackle these corner cases when it may concern. When the alarm sounds be quick to land, otherwise you run the risk of completely depleting the battery, which is not good for the battery, but it could also potentially crash your model. LiPo Battery discharge rate range from 1C to 55C. A 2200mAh battery at full charge can provide a current of 2200 milliamps for one hour before it becomes fully discharged. This connector is commonly used by manufacturers and products such as Losi, Skytec, Walkera (Ladybird), Hubsan , Mini CP and Genius CP. Proper LiPo Storage Voltage = 3.8V per cell. Below are some pictures showing these connectors and their dimensions. This means that you can safely draw up to 44Amps from that pack, without damaging it. And it would take 1 hour to complete the charge. There are clones of this design and many of the clones plastic will melt if you get your soldering iron too hot when attaching your wires. What does High Discharge LiPo Battery Mean? Airplanes and helicopters don't really have a standard capacity, because they come in many different sizes, but for R/C cars and trucks, the average is 5000mAh - that is our most popular battery here in the store. Lithium also combusts when reacting with oxygen, but only when heated. Lithium is analkali metal, meaning it reacts with water and combusts. The capacity of a battery is basically a measure of how much power the battery can hold. This energy is drawn by the motors and rotors. Leave the battery in the salt water bath for at least 24 hours. The colder it is, the shorter your run times will be due to the slowing down of the chemical activity within the battery. 100+. Always remember that heat is the number one enemy of LiPo batteries. If there is no proper space for charging, one can use a LiPo battery safety charging bag instead. Answer: We manufacture 3.7V Lithium polymer battery cells, meantime, different LiPo battery packs are also available for us. It is recommended to always charge the battery the same day you plan to go to the flying field.
