Professional panasonic lithium battery 3v series for drones

CR2050B2 can be customized for additional processing, add solder chip terminals, insulation packaging and configuration type, the model as following: CR2050B2/FCN, CR2050B2/HCN. The basic parameters of this wide temperature battery are as follows: CR2050B2 3V345mAh, size 20*5mm, temperature is -40~120 °C. From the following Discharging Characteristics by Temperature, you can see how the battery operates at the same load and at different temperatures. When used at -30 °C ambient temperature, the voltage is 2.6V. After 500h, we can see that the voltage is kept at 2.55V. After 1500h, the voltage drops to 2.48V. After 2000h, the voltage drops rapidly to 2.3. V, and the apparent decline is accelerated until the end of about 2450h. When used at 0 °C ambient temperature, the voltage is 2.9V. After 500h, we can see that the voltage is kept at 2.9V. After 1500h, the voltage drops to 2.75V. After 2000h, the voltage drops rapidly to 2.3V. And the apparent decline is accelerated until the end of about 2050h. When used at an ambient temperature of 20 ° C, the voltage is 2.98V. After 500h, we can see that the voltage drops slowly to 2.8V. After 1500h, the voltage drops to 2.8V. After 2000h, the voltage drops rapidly to 2.35. V, and the apparent decline is accelerated until the end of about 2050h. When used at an ambient temperature of 60 ° C, the voltage is 3.05 V. When 500 h is used, we can see that the voltage remains at 3.05 V. After 1500 h, the voltage drops to 2.9 V, and the apparent drop accelerates until about 1950 h ends. When used at an ambient temperature of 85 ° C, the voltage is 3.1 V. After 500 h of use, we can see that the voltage remains at 3.1 V. When 1500 h is used, the voltage drops to 2.9 V, and the apparent drop accelerates until about 1900 h.
