DJI T100 Dual-Battery Spraying: Preflight e Guia de Segurança
O DJI T100 Dual-Battery Spraying System (LS100-DB) opera com duas Intelligent Flight Batteries e tem 90 kg de operating payload publicado. O preflight precisa validar battery pairing, firmware, cabos, payload recommendation e a condição do sistema IPX6.
Resumo: confirme T100 + firmware compatível; use duas batteries idênticas; revise cabos e mechanical hardware; não ultrapasse a recomendação do DJI Agras; verifique seals/covers; não desmonte factory-installed parts. DJI publica tank de 100 L, operating payload de 90 kg e cerca de 50% mais hover time no mesmo payload.
1. LS100-DB é somente para T100
Não use em outros aircraft ou non-agricultural use.
2. Firmware support é obrigatório
Aircraft firmware precisa reconhecer o system.
3. Duas batteries devem ser idênticas
DJI exige identical batteries para dual-battery spraying/lifting.
4. DB2160/DB2212
Podem aparecer conforme market; não misture os modelos no mesmo pair.
5. Battery-pair check
- same model;
- no damage;
- clean connectors;
- no warnings;
- fully seated;
- no voltage/capacity mismatch.
6. Tank volume
100 L.
7. Operating payload
90 kg.
8. App recommendation matters
Do not overload.
9. 90 kg is not universal target
Environment and aircraft state can reduce recommendation.
10. Endurance
DJI reports ~50% more hover time at same payload.
11. Plan the longer sortie
Route, spray volume and reserve still matter.
12. Secure cable connections
Correct and firm.
13. Inspect cable damage
Abrasion, pinching, contamination, bent connectors.
14. Mechanical injury risk
Hands-on checks with aircraft powered down.
15. Do not disassemble factory parts
Ingress protection can be affected.
16. IPX6
Under stable lab conditions.
17. Not permanent
Aging/wear reduce protection.
18. Collision
Seal deformation matters.
19. Cracked seals
Require inspection/service.
20. Waterproof covers
Must be fully secured.
21. Water damage warranty
Do not assume coverage from IPX6 rating.
22. Battery preflight
- same model;
- inspect shells/connectors;
- no swelling/leak/impact;
- install fully;
- review DJI Agras;
- stop on mismatch/error.
23. Spray-system preflight
- LS100-DB installed;
- tank secure;
- hoses/connectors;
- nozzles;
- no leaks;
- flow/spray status;
- covers secured.
24. Firmware/app check
No unsupported-device or payload errors.
25. Takeoff-weight check
Use current payload recommendation.
26. SOC/voltage balance
Resolve mismatch before takeoff.
27. Route planning
Longer endurance still needs return reserve.
28. Payload and endurance
Higher payload increases demand.
29. Label battery pairs
Useful for fleet consistency.
30. Record each sortie
- battery A;
- battery B;
- model;
- starting charge;
- warnings;
- payload recommendation;
- actual payload.
31. Post-flight inspect both packs
Both are part of the same energy system.
32. Cool before next rotation
Use correct charging/cooling workflow.
33. Do not keep a damaged battery just to preserve a pair
Safety first.
34. One-pack warning
Record exact battery and warning.
35. Payload not recognized
Check firmware/connections/install.
36. App recommends below 90 kg
Use lower recommendation.
37. Collision damage
Reinspect ingress protection.
38. Loose waterproof cover
Service finding.
39. SOP

45. Dual-battery operation deve ser tratada como um matched energy system
O benefício de duas batteries vem da operação coordenada dos dois packs. Isso significa que inspection, state of charge, warning history e cooling devem ser avaliados como um par, não como duas batteries independentes que apenas cabem no aircraft.
46. Battery-pair history melhora troubleshooting
Se um warning aparece somente quando dois packs específicos operam juntos, registre essa combination. Depois compare cada pack com um known-good pair através de procedimentos suportados. Isso ajuda a separar battery-specific fault, pairing mismatch e aircraft-side issue.
47. Payload planning deve considerar a mission completa
Mesmo com 90 kg de published operating payload, planeje chemical volume, route length, expected spray rate, elevation, wind e battery reserve em conjunto. Um payload menor pode produzir um ciclo operacional mais eficiente quando reduz turnaround ou melhora reserve.
48. Cooling deve ser aplicado aos dois packs
Após a sortie, não envie apenas o pack mais quente para cooling. Registre a condição de ambos e mantenha uma rotation clara para evitar que um battery volte ao aircraft antes de atingir uma condição apropriada.
49. Structural inspection depois de heavy operation
Dual-battery spraying aumenta o tempo que aircraft e payload system permanecem trabalhando por sortie. Inspecione mounts, cables, covers e spray-system hardware de forma consistente, especialmente após transport, collision ou unusual vibration.
