Emergency Response Drone Batteries
Safe, ready-to-fly power for firefighting, search and rescue, lifebuoy drops and medical delivery drones, built on semi-solid-state cells with high thermal stability.
| Typical pack | 6S–14S, 30–72Ah |
|---|---|
| Safety | Cells pass nail penetration testing |
| Cold weather | Strong discharge below -20°C |
Emergency missions leave no margin
When a drone launches to a fire, a flood or a missing person, there is no time to wait for a battery or to doubt its charge. Packs must sit ready, fly in harsh conditions and stay safe close to heat.
Safety near heat and impact
Firefighting drones work close to flames and hot air. Semi-solid-state cells offer higher thermal stability and pass nail penetration tests, reducing fire and explosion risk compared with conventional LiPo.
Ready on the shelf
Response teams keep aircraft charged and waiting. State-of-charge reporting from the BMS shows at a glance which packs are ready to fly.
Heavy, changing payloads
Hoses, extinguishing agents, lifebuoys and medical kits load the aircraft unevenly and change its weight mid-flight. Packs are sized with discharge headroom for climb and release.
Rain, smoke and cold
Our pack designs go through rain, salt spray and thermal shock testing, and the cells keep discharging below -20°C for winter and mountain rescue.
How we configure an emergency response pack
Reliability and safety come before maximum endurance. These are the choices we make with response teams and their drone suppliers.
| Cell grade | SLD3 350 Wh/kg cells for a balance of energy, discharge rate and cost; SLD4 400 Wh/kg where flight time is critical. |
|---|---|
| Series and capacity | 6S to 14S and 30Ah to 72Ah for typical firefighting, rescue and delivery multirotors. |
| Discharge | 3C continuous with 10C peak on the SLD3 range, for winch, hose and drop payloads. |
| BMS | Balancing, protection and state-of-charge reporting, with communication to the flight controller. |
| Tethered systems | On tethered firefighting drones the onboard pack is the backup if ground power is interrupted. We size it for a controlled return and landing. |
| Charging | Dual- and four-channel EV-PEAK chargers for vehicle or station-based charging. |

Frequently asked questions
Why use semi-solid-state batteries on firefighting drones?
Firefighting drones fly close to heat and face a higher risk of impact. Semi-solid-state cells have higher thermal stability and pass nail penetration tests, so they are less prone to thermal runaway than conventional LiPo, while also storing more energy per kilogram.
What battery do rescue drones for lifebuoy and medical drops need?
Most rescue and delivery multirotors use 6S to 14S packs sized for the heaviest payload plus a safe reserve. We usually recommend 350 Wh/kg SLD3 packs for their balance of discharge rate and energy, with capacity customised to the airframe.
Can the batteries operate in winter rescue conditions?
Yes. Our semi-solid-state cells keep strong discharge performance below -20°C. For best results, store packs indoors and launch soon after taking them out.
Do you supply chargers for response vehicles?
Yes. We supply EV-PEAK dual- and four-channel UAV chargers and recommend models that match your pack configuration and available power supply.
