Professional diagnosis and repair of drone battery packs for recreational, commercial and agricultural drones. We service lithium-based energy systems, including DJI smart batteries, agricultural spray drone batteries and high-discharge FPV packs.
Battery Failure Diagnostics & Restoration
Our workshop handles:
- BMS controller faults
- Cell imbalance issues
- Voltage sag under load
- Dead/no-boot conditions
- Charge/discharge failures
- Firmware lockouts (model dependent)
- Thermal shutdown faults
- Connector and harness faults
Supported Battery Types
We service lithium polymer (LiPo), high-voltage LiHV and lithium-ion (Li-ion) packs used in:
- DJI Mini / Mavic / Air / Phantom / Inspire
- DJI T-Series agricultural drones
- Autel EVO
- FPV quads (3Sā6S)
- Fixed-wing & VTOL platforms
Common Root Causes of Battery Failure
Drone batteries can fail due to:
- Cycle wear
- Cell imbalance
- Over-discharge events
- Storage neglect
- Water ingress
- Crash impact
- BMS controller failure
- Excessive current draw
- High operating temperatures
Repair & Rebuild Services
Where viable, we can:
- Recell packs (model dependent)
- Recalibrate BMS controllers
- Restore balance conditions
- Replace harnesses and connectors
- Perform cell matching & testing
- Diagnose smart battery firmware issues
Note: Some closed ecosystem batteries (specific DJI models) may have firmware-imposed safety locks that define what is repairable vs. replace-only. Units are assessed individually.
Agricultural Battery Repairs
Agricultural spray drone batteries operate in high-load environments and typically fail due to thermal stress and elevated cycle counts. We diagnose and service agricultural packs where component access and BMS compatibility allows.
Testing & Validation
Each battery undergoes:
- Capacity testing
- Load testing
- Balance checks
- Thermal performance checks
- Charge/discharge validation
Turnaround & Logistics
Courier intake for all provinces. Standard repairs take 5ā10 working days depending on model and parts availability. Agricultural systems may require extended lead times for BMS-specific components.
Warranty & Limitations
Warranty applies to replaced components after successful testing. Packs with severe water ingress, cell perforation or thermal runaway damage may be classified beyond economical repair.
Frequently Asked Questions
Can DJI smart batteries be repaired?
In many cases, yes. Failures caused by cell imbalance, BMS faults or connector issues may be repairable after assessment.
Can drone batteries be rebuilt?
Yes, depending on form factor, firmware protections and pack architecture. Some models support recell and recalibration, others do not.
Can agricultural drone batteries be serviced?
In many cases, yes. Failures caused by cell imbalance, BMS faults or connector issues may be repairable after assessment.
Do repaired batteries perform like new?
Performance depends on the condition of the original BMS and controller hardware. Recelled packs with matching cells can restore usable capacity.
