Lithium Battery Storage

Lithium batteries must not be stored for more than a few days fully charged. Storing lithium batteries fully charged reduces their life and their capacity.

The SwellPro Balance Charger includes a convenient STORAGE charge mode. This mode assesses the state of charge of the battery and automatically performs a balanced charge or discharge cycle to achieve the optimum storage state for Lithium batteries.
Batteries stored for an extended period of time without use should be STORAGE charged every 3 months.
Programs [04], [05] and [06] are STORAGE charge cycles for the three standard SplashDrone battery types as per the table on page 5.

Battery testing

The Charger can detect the voltage of a single battery, the charger input and output voltage, and the internal and external temperature of the charger. The detected information is used to determine whether the battery is damaged.

Battery voltage measurement

1. Press STOP until the Battery Meter menu appears.
2. Press “START” to confirm, the current voltage of each cell inside the battery is displayed.
3. Press the DECREASE button to view the charger input and output voltages, as well as the temperature.
   If any cell voltage is lower than 3.0V, the battery pack has been over- discharged. This battery may no longer be usable and will have diminished capacity.

Battery Resistance Measurement

1. Press STOP until the Battery IR menu appears.
2. Connect the battery,to be tested and press “START” . The charger will display the internal resistance of the battery.

Internal resistance detection accuracy: ± 5mΩ.
Batteries a re consumable components. Through use and age, their performance decreases and they need to be replaced.
The performace and age of Lithium batteries can be gauged by measuring the internal resistance. The lower the internal resistance, the better the discharge performance of the battery.

• SD3+ LiHV drone battery internal resistance reference value: ≤ 15mΩ
• SD3+ LiPO remote control battery internal resistance reference value: ≤15mΩ
• SD3 LiPO drone battery internal resistance reference value: ≤ 11mΩ

As the battery ages and the number of discharge cycles increases, the internal resistance of the battery will gradually increase and the discharge performance of the battery will decrease.
If battery capacity drops dramatically, the internal resistance will also have increased and it is recommended to replace the battery.
