Battery, Li-Pol, 11.1V, 2200mAh, 20C, ZippyFlightmax Battery Li-Pol 11.1V/2200mAh (20C) from Zippy. Li-Pol battery with high-current (up to 66A at peak times) at an interesting price. The battery connector is fitted by T-Dean. The maximum long-term discharge current 44A. Dimensions (mm): 104x35x23 Lithium Polymer (Li-Pol) batteries are the latest energy source. They excel in low weight (180g) and excellent discharge characteristics.
Lithium Polymer (Li-Pol) batteries are the latest energy source. They excel in low weight (180g) and excellent discharge characteristics. Due to an entirely different type of electrochemical reactions occurring inside cells they are made completely different than conventional NiCd or NiMH batteries.
Voltage Li-Pol cell is 3.7V (unlike 1.2V NiCd and NiMH batteries). In operation they should in no case exceed 4.2V for cell voltage during charge and fall below 3V. Exceeding these values probably leads to irreversible damage of the battery. In normal operation, the voltage (before you start charging the battery) should not fall below 3.5V. If you find before charging that voltage is lower, batteries discharge excessively.
For this reason, it must be used to charge the special battery charger for Li-Pol batteries, as well as use special protective circuit (Alarm Li-Pol), which alerts you to critical battery discharge.
Protect cells against damage - trance electrodes, puncture. In case of damage of cell can cause to internal short circuit with explosion and fire. Do not puncture "inflated" cells - inflation is a sign of internal damage. During charging place the battery on a fireproof pad, or place to the Li-Pol Safe Bag. The vicinity must be free without fla mmable objects or liquids. The manufacturer recommends storing batteries charged at 70% of capacity.
