MAD 12S 27Ah A+ Drone Solid State Lithium-ion Battery Pack 44.4V 1198.8Wh 3C/5C

Overview

The MAD 12S 27Ah A+ drone solid state lithium-ion battery is a 12S 27000mAh (27Ah) pack rated at 44.4V nominal and 1198.8Wh energy, designed to power drone flight systems with a hard-pack form factor and fixed-position cable routing.

Key Features

• Semi-solid battery system; cell safety improvements include surface flame-retardant coating, electrolyte flame-retardant additives, and a semi-solid system design.
• Design optimization (three major design optimizations): material ratio adjustment, optimal density, and custom auxiliary materials (earpieces and aluminum-plastic film) to enhance energy density.
• Comprehensive protection structure: four 0.5mm thick FR4 fiberglass panels for lateral reinforcement; protection capability stated as increased by 87%.
• Bottom strengthening: 2mm thick EVA shock-absorbing foam for impact cushioning during rapid UAV acceleration.
• Hard-pack appearance optimization: square/flat pack with accurate outline size control; cables routed in fixed positions.

Material innovation (cell design notes)

1. Add ionic conductor additives to the electrode sheet to improve ionic conductivity and high-rate performance under low electrolyte infiltration conditions.
2. Add lithium source additives to the pole film to improve the first effect of the material.
3. Use a self-developed double lithium salt electrolyte formula, considering high/low temperature, circulation, and magnification of the battery cell and other electrochemical properties.

Safety Notes (Storage & Charging)

Battery storage conditions and precautions

1. Keep away from flammable materials when storing.
2. Do not disassemble and assemble the battery.
3. If the battery has been charged and is damaged, dispose of it properly in time and do not use it again.
4. If odor, heat, discoloration, deformation, or other abnormality occurs during use, storage, or charging, immediately remove the battery from the device/charger and stop using it.

Battery charging conditions and precautions

1. Do not charge at a current greater than 2C.
2. Use a qualified smart charger.
3. Someone must be present during the charging process.
4. Keep away from flammable materials when charging; overcharging may cause fire or battery rupture.
5. Connecting the positive and negative electrodes can lead to a short circuit and serious hazard.

Service Notes

• Battery damage and injury caused by failure to operate according to the prompts shall be borne by the user.
• Battery damage caused by artificial overcharge and overdischarge cannot be replaced.
