Assistant 2 app.
3.  Balancing Function: Automatically balances the voltage of each battery cell when 
charging.
4.  Overcharge Protection: Charging stops automatically when the battery is fully 
charged.
5.  Temperature Protection: The battery will only charge when the temperature is between 
5-45° C (41-113° F).
6.  Overcurrent  Protection:  Battery stops  charging  when  high amperage (>  10  A)  is 
detected.
7.  Over-Discharge  Protection: To prevent serious damage  to the battery, current output 
will be cut off when the battery cell is discharged to 2.8 V and not in use. To extend 
operating times, overcharging protection is disabled as batteries discharge during 
usage. In this instance, a battery voltage below 2 V may cause a safety hazard such 
as a re when charged. To prevent this,  the battery will  not be able  to charge if  the 
voltage of a single battery cell is below 2 V. Avoid using any batteries matching this 
description. Always be alert to  avoid over-discharging to  prevent permanent battery 
damage.
8.  Short Circuit Protection: Automatically cuts the power supply when a short circuit is 
detected.
9.  Battery Cell Damage Protection: DJI Assistant 2 displays a warning message when 
detecting a damaged battery cell.
10.  Sleep Mode: Sleep mode is entered to save power when the battery is not in use.
11.  Communication: Battery voltage, capacity, current, and other relevant information is 
provided to the gimbal.
12.  Pairing Batteries: Powered by two batteries (with battery cells connected in parallel), 
the Ronin 2 requires the two batteries to have similar properties, e.g., internal 
resistance. Pairing batteries in the beginning is recommended. Pairing can be done 
using DJI Assistant 2, which will also prompt when batteries that are not paired are in 
use. The Intelligent Battery Charging Hub will charge paired batteries simultaneously. 
13.  Heating: Batteries can work even in cold weather. Refer to "Using the Battery" section 
for details.
Read the user manual, disclaimer, and battery safety guidelines before use. Users 
take full responsibility for all operations and usage.
Charging the Intelligent Battery
The Ronin 2 Quad Charging Hub is designed for use with the Ronin 2 Battery Charger. It 
charges up to four Intelligent Batteries simultaneously. The battery pair with more stored 
power will be charged rst. If batteries are not paired, the Charging Hub will intelligently 
charge batteries in sequence according to battery power levels from high to low. Pairing 
can be carried out using DJI Assistant 2.
