DJI Agras T70P: Intelligent Flight Battery — Cooling, LEDs, Storage e Maintenance
DJI Agras T70P: Guia de Intelligent Flight Battery — Cooling, LEDs, Storage e Maintenance
O battery chapter do DJI AGRAS T70P User Manual v1.0 (2025.11) cobre charging, cooling, LEDs, low-temperature operation, storage, transportation, maintenance e disposal. Distinção importante: o chapter usa DB1580 como illustrated example, enquanto a performance table usa uma 41,000 mAh Li-ion flight battery nos performance tests.
Resumo: battery off antes de connect/disconnect. DJI diz não voar abaixo de 15%. Depois do voo, cool hot battery antes de charging. Charge range: 0°C–60°C; ideal 22°C–28°C. Charge one battery at a time. Para long-term storage, power off/disconnect, keep dry e leve critically low pack a 40–60%. Full charge/discharge pelo menos a cada 3 meses.

Fonte e revisão
Fonte: DJI AGRAS T70P User Manual v1.0, 2025.11, section 6. DB1580 is illustrated example; performance table separately references 41,000 mAh Li-ion flight battery.
75. A source usa DB1580 como illustrated example — preserve essa distinção
O battery chapter mostra DB1580 como example, enquanto a performance table do T70P usa uma 41,000 mAh Li-ion flight battery nos published tests. Não renomeie o illustrated battery para DB2160 sem exact configuration verification.
76. Power off antes de conectar ou desconectar
A flight battery deve estar powered off antes de connection/disconnection com o aircraft. Isso vale para normal handling, não apenas maintenance.
77. Não voe abaixo de 15%
A DJI orienta não continuar flight abaixo de 15% battery level. Esse threshold pertence ao battery-operation guidance desta source.
78. Hot battery precisa resfriar antes de charging
Depois do flight, use o official air-cooled heat sink ou um suitable heat-dissipation device. Se a battery estiver quente, charging pode não ser permitido.
79. Charging range e ideal range são diferentes
Charging temperature: 0°C a 60°C. Ideal: 22°C a 28°C. Operar no permitted range não significa que toda temperatura seja igualmente desirable.
80. Charge one battery at a time
A source diz para carregar uma battery por vez para não comprometer heat dissipation.
81. Four LEDs flashing rapidly = abnormal/unavailable
Esse pattern deve retirar o pack do normal use até que o issue seja entendido. Não trate como simples low-charge indication.
82. Low-temperature preparation
Antes de cold-weather operation, a battery deve estar acima de 5°C e idealmente acima de 20°C. O manual diz que hover pode aquecer a battery.
83. Transport e storage usam thresholds diferentes
Para long-term storage, se critically low, carregue para 40–60%. Para transport, a source diz não transportar damaged battery ou pack acima de 30% e recomenda discharge para 25% ou menos.
84. Maintenance interval
Faça full charge/discharge pelo menos uma vez a cada 3 meses. A source também diz que uma battery sem charge/discharge por 5 meses ou mais deixa de ser coberta pela warranty.
85. Battery lifecycle record
- battery ID/model;
- aircraft configuration;
- last full charge/discharge date;
- heat events;
- LED error pattern;
- transport state;
- storage state;
- terminal/port inspection;
- cooling equipment used.
