Charging the battery

This section mainly describes how to charge lithium batteries. It is recommended that the battery be fully charged before each outdoor flight.

Warning

Because UAV configurations vary, the charger supplied may differ. Refer to the applicable charger tutorial below based on the charger model you received.
1. The battery used in this product is a 4s1P lithium polymer battery pack (LiPo). The full-charge voltage of each cell is 4.2 V, the low-voltage level of each cell is 3.7 V, and the rated capacity is 5000 mAh.
2. For maintenance, avoid direct sunlight and moisture, keep the battery away from high temperatures, and store it in a dry, cool place. A fireproof bag or explosion-proof box is recommended for storage.
3. Chemical reactions inside a fully charged lithium polymer battery are relatively active. Storing the battery fully charged for too long causes it to age and reduces its discharge capacity. The optimal storage voltage is approximately 3.85 V.
4. If the UAV remains powered on but unused for an extended period, be sure to remove the battery. The indicator light board continues to draw a small amount of power, and extended storage may completely drain the battery, causing overdischarge and rendering it unusable.

Charger 1 overview

Use the balance lead adapter cable and XT60 adapter cable to connect the battery to the charger. Select LiPo as the battery type, set the charging current to 3 A, and then start charging.

Charger 2 overview

We use the C1-XR smart balance charger to charge the battery. The C1-XR charger is briefly introduced below; for details, see the manual: C1-XR Smart Balance Charger

4S 5000mAh lithium battery

Connection procedure

• Connect the power supply: As described in the charger overview, connect charger power cable 12 to an AC outlet (100~240V AC power supply).
• Connect the battery: Connect balance adapter board 13 and battery balance connector 14 to the 4S 5000mAh lithium battery.

Voltage measurement

This battery is a LiPo battery. After connection, the voltage of each cell can be measured: the full-charge voltage of each cell is 4.2 V, and when the voltage of any cell is close to or below 3.7 V, stop flying and charge the battery promptly.
