It is 2 series of 7.4V lipo battery of 603450-1100mAh. It combines 2 cells and 1 PCM into one battery. Its rated voltage is 7.4V.
The landing page is about 2S 7.4V 603450-1100mAh battery pack. 603450 refers to thick 6mm, width 34mm, length 50mm. As it is 2 series battery pack, it shall 2 cells layout into one battery pack. So its thick will be 14mm. After soldering PCM, the length will be increased 2~3mm. So that’s basic lithium polymer battery dimension explanation.
Following is our battery safety protection performance:
No.1 Over-charge protection
Test method and condition: At 20±5℃ conditions , after fast-charging, use an external 5V power to charge the battery and last for 24 hours, then check the appearance of battery.
Criteria: The appearance is normal, no explosion, no fire, no smoking, no leakage.
No.2 Over-Discharge Protection
Test method and condition: At 20±5℃ conditions, discharge battery to 2.5V with 0.2C constant current, then discharge with 30Ω loading for 24 hours. Check the appearance of battery.
Criteria: The appearance is normal, no explosion, no fire, no smoking, no leakage.
No.3 Short-Circuit Protection
Test method and condition: After fast-charging, use a cable of 0.1Ω resistance to short the battery for 24 hours. Then check the appearance of battery. Cut circuit of resistance test the battery’s voltage after charging with 1C constant current for 5 seconds.
Criteria: The appearance is normal, no explosion, no fire, no smoking, no leakage.
In order to prevent the battery possibly occurs leaks, over heat, swollen, please note the preventive measure.
