Charging & Usage Notes
- Full charge voltage (LiHV): 4.35V
- Recharge guidance: charge in time when flight voltage drops to 3.6V
- Do not over-discharge: single-cell voltage must not be lower than 3.5V
- Long-term storage: maintain single-cell voltage at 3.80V-3.85V; perform a charge-discharge activation within 3 months
Warnings
- Please read the battery parameters and instructions in detail before use.
- Please don’t charge the battery unattended.
- Do not overcharge (select the correct battery type before charging; LiPo full charge voltage per cell is not more than 4.2V; LiHV full charge voltage per cell is not more than 4.35V).
- Do not over-discharge (the single-cell discharge voltage of LiPo and LiHV batteries cannot be lower than 3.5V; over-discharging will damage the battery and cause swelling).
- Don’t place the battery close to open flames or fire sources.
- Keep the battery away from flammable materials when charging.
- Please carefully check the battery voltage and capacity before charging and use.
- It is forbidden to reverse the positive and negative poles of the battery (to avoid short circuit).
- Do not directly touch the leaking battery. If electrolyte contacts skin, wash with clean water immediately. If severe, consult a doctor.
- Please dispose of the ruptured battery in time and do not reuse it.
- It is forbidden to disassemble and reassemble the battery or change the wiring (it is easy to cause short circuits and burning).
- If a collision occurs during use, please remove the battery and check whether the battery and connector are normal.
