DJI Ronin/Ronin M 3400mAh Rechargeable Intelligent Gimbal Battery 14.8V

DJI provided battery usage instructions for their customers (both for gimbals or aerial devices) which you may find helpful:

Please remove the battery from the device while it is not being used and keep it in a temperate environment to prevent the battery from overheating or freezing.

Do not charge the battery right after use; wait until it cools down. The charging environment should be between 32° to 113°F (0℃ to 45℃). Take care of the battery to avoid accidents.

Be aware of the battery during transport. A vehicle accelerating or decelerating and may cause the battery may collide with sharp objects and combust or cause other damage. Please keep batteries in a safe place while transporting in a car to prevent fires.

Check the status of battery before using. Lack of usage or over usage may deplete battery power or lead to deviations in voltage level between the battery cells because of incomplete charging and discharging operations. Normally, these problems will arise if the battery is within a 0.2V voltage deviation.

Please recycle a damaged battery, since lithium batteries are greatly harmful to the environment.

Suitable storage power range is from 50% to 65% if the battery is unused for a long time.

While using the battery under low temperature environment, between -10℃ to 4℃, the internal resistance of the battery increases which leads to heavy drop in voltage. Therefore, please fully charge the battery before using. The voltage of battery cells reaches 4.35V. While the temperature is lower than 5℃, the battery needs to be fully charged, the voltage of battery cells should be higher than 4.2V, and warm-up and heat preservation actions should be taken before launching. If you are using an aerial device with this battery, the warm-up can be achieved with the battery heater or by hovering the aircraft at a low altitude for around one minute.
