Charging and Usage Notes

• Use only a charger that supports 4S HV lithium batteries.
• The maximum charging voltage is 17.8V, equivalent to 4.45V per cell.
• A standard 4S LiPo charger limited to 4.20V per cell will not fully charge this battery.
• Confirm that the ESC, motor, power distribution system, voltage regulator, and other electronics can tolerate a fully charged voltage of 17.8V.
• Do not exceed the specified 27A maximum continuous current.
• The product is labeled 10C, but the provided specification image only confirms 5C continuous discharge. No separate peak-current duration is stated.
• Always verify connector compatibility before use.
• Charge the battery only with a suitable balance charger and never leave it unattended while charging.
• Do not charge or use a swollen, punctured, damaged, leaking, or overheated battery.
• Store the battery in a cool, dry, fire-resistant location.

Voltage clarification: 15.8V is the nominal voltage, while 17.8V is the fully charged voltage.
