Swiss Arms LiPo Battery 11.1V 1200mah 25c - Mini-Tamiya

The main advantage of LiPo batteries is their power-to-size ratio. They are very compact in size while maintaining very high current efficiency, which allows you to choose the right battery for virtually every AEG replica.

Remember that a LiPo battery should not be discharged below 3 V per cell and should not be charged above 4.2 V per cell. Another advantage of LiPo batteries is their low self-discharge rate. An unused battery loses about 3-5% of its energy per month.
