Battery Not Charging
Holy Stone Drone
Severity:What Does This Error Mean?
Holy Stone battery not charging is usually a deeply discharged battery or an incompatible USB charger. Use the original charging cable and a 5V 2A wall charger — not a computer USB port.
Affected Models
- Holy Stone HS720E
- Holy Stone HS360E
- Holy Stone F11S
- Holy Stone HS175D
- Holy Stone HS710E
Common Causes
- Battery fully discharged below the LiPo recovery threshold
- USB charger not providing enough current
- Faulty charging cable
- Battery swollen from overcharging or age
- Charging port on the battery damaged
How to Fix It
-
Use the original Holy Stone charger and a 5V 2A wall adapter.
Computer USB ports typically provide only 0.5A — not enough for drone batteries. Plug the charger into a wall socket using a 5V 2A adapter. The charging indicator LED turns red when charging and green when full.
-
Try a different charging cable.
The supplied USB cable can fail at the strain relief point near the connector. Swap for another cable of the same type to rule out a bad cable.
-
Leave a deeply discharged battery on charge for 30 minutes.
A fully drained LiPo may show no LED activity initially. Leave it connected to a wall charger — a slow recovery charge may begin after 20-30 minutes.
-
Inspect the battery for swelling.
Place the battery on a flat surface. A swollen battery rocks back and forth instead of sitting flat. Swollen LiPo batteries must be safely disposed of at a battery recycling point — do not charge or use.
-
Store batteries at 50-70% charge if not flying for more than a week.
Long-term storage at full charge damages LiPo batteries and reduces capacity. Discharge to about 50% before storing. Recharge fully before your next flight.
Frequently Asked Questions
How long does a Holy Stone drone battery last per flight?
The HS720E gives about 23-26 minutes of flight time per battery. Actual time is shorter in windy conditions, cold weather, or aggressive flying.
Can I fly while the battery is charging?
No. Never fly while the battery is connected to a charger. Always charge batteries completely before inserting them into the drone.
