How to choose FPV battery charger?deep cycle marine battery Manufacturing

　　1. current

　　The battery generally uses C numbers (that is, multiplier) to indicate the battery power and discharge capacity. You will find that many FPV batteries will be marked with 25C, 30C and so on. How do you understand?

　　1C represents the current strength when the battery is fully discharged for one hour. For example, the battery discharge of 1000mAh capacity is 1h to 1C. At this time, the discharge current is 1A, so how long does it take for 25C to discharge? It can be known that it is 0.04h, that is, 2.4 minutes, that is, the discharge current is equivalent to 25 times, that is, 25A discharge capacity. This is just a matter of discharge, charging is also similar. When choosing the FPV battery charger, you must look at the maximum charging and discharge current supported by the charger.

　　2. Voltage

　　The current FPV batteries are generally lithium polymer batteries, and because higher voltage is required, it is generally more stringed and combined. For example, you are common 3S1P and so on. Generally speaking, the voltage of a single -section battery of the lithium polymer battery is 3.7V and 4.2V after full electricity. Each cell is easy to cause a variety of dangers if it is over. And our IMARS III balance charger can easily control the charging voltage through a simple choice when charging, so that users can use it safer.

　　3. Power

　　Many times, power is also an important measure. Calculated based on the formula of physics: p (power) = u (voltage)*i (current). For example, a 3000mAh 3S1P battery means that the current has 3A, and the battery full electrical voltage of 3S is 12.6V, so the overall power is 37.8W. If your FPV battery charger is not enough, it is very embarrassing. The maximum charging power of the IMAX B6 is 80W, and the maximum charging power of our IMARS III is 100W.
