How to choose FPV batteries?

　　When we choose the FPV battery, have we noticed the mark on the inner ring? Generally speaking, the batteries and bracelets sold by regular brands are marked with marks. We can distinguish from these logos with the price signing and testing certificates.

　　1. Lithium battery label. The labels of lithium batteries are similar to that of other logo markers. They should include product names, quality, product standard numbers, production enterprises (or sales enterprises) names and addresses, product quality inspection certificates, Chinese warning descriptions (necessary hour);

　　2. FPV lithium battery label (parameter). The content of the stipulated mark includes the skewers and the number of single -chip cell voltage. The so -called 4S in the FPV battery is composed of 3 lithium batteries in series (4S1P), that is, the voltage of each battery cell is 3.7V. The actual voltage of the single -piece lithium battery is 2.75 ~ 4.2V, and the power capacity on the lithium battery is 4.2V discharged to 2.75V.

　　The FPV lithium battery must be used within the voltage range of 2.75 ~ 4.2V. If the battery voltage is lower than 2.75V, it is over -discharging, the lithium battery will swell, and the internal chemical liquid will crystallize. These crystals may pierce the internal structure layer and cause a short circuit, and even make the lithium battery voltage zero. The voltage of the remote control model lithium battery is higher than 4.2V. It is over -charging. The internal chemical reaction is too intense. Lithium battery will swell and swell. Whether it is too much or over -charged, it will cause great damage to the remote control model lithium battery.
