Product Specification

Professional 4S LiPo Battery for Drones - 15.4V 5000mAh (77Wh) to Maximize Flight Time of Cinematography & Heavy Lift UAVs

Features

• Exceptional Energy Density (77Wh): Offers one of the highest energy outputs in its class, enabling significantly longer operation times between charges.

• High Voltage (LiHV) Platform: The 15.4V (4.35V/cell) chemistry provides a higher voltage plateau, which can translate to more power and efficiency for compatible devices.

• Favorable Power-to-Weight Ratio (~229 Wh/kg): Provides an excellent balance of high capacity and manageable weight, crucial for aerial performance.

• High Discharge Capability: Engineered to support high continuous discharge rates (C-rating dependent), suitable for applications with burst power demands.

Specifications

Applications

• Large Multirotor Drones & UAVs: Heavy-lift professional drones for aerial cinematography, surveying, mapping, and agricultural spraying requiring maximum flight time.

• Long-Range FPV Drones: FPV racing and long-range exploration drones where extended flight duration is essential.

• High-Performance RC Vehicles: Large-scale RC cars, trucks, and boats that demand high capacity for longer run times.

• Professional Electric Tools & Equipment: For cordless equipment used in filming, construction, or landscaping.

Warnings & Precautions

Charging

• Charger Requirement: You MUST use a balanced charger specifically for LiHV (High Voltage LiPo) batteries. Standard LiPo (4.20V/cell) settings are insufficient and unsafe.

• Never Unattended: Always charge on a non-flammable surface inside a LiPo safety bag/container. Never leave charging batteries unattended or charge overnight.

• Environment: Charge in a well-ventilated area, away from flammable materials, children, and pets.

Discharging

• Voltage Monitoring: Never discharge below 12.0V (3.0V per cell). Use a battery monitor or low-voltage cut-off (LVC) on your device. Over-discharge ruins cells and creates safety risks.

• Temperature Management: Discontinue use if the battery pack exceeds 60°C (140°F). 

• Short Circuit Prevention: Always insulate terminals when not in use. Use connectors carefully to avoid accidental shorting, which can cause instant, severe fires.

• Damage Inspection: Before and after each use, inspect for physical damage: dents, swelling, punctures, or leaking electrolyte. IMMEDIATELY DISCONTINUE USE of any damaged or swollen/puffy battery.

Storage

• Storage Preparation: For any storage period over 3 days, charge/discharge the battery to Storage Voltage (approx. 15.2V-15.4V) using your charger's "Storage" function.

• Transportation: When transporting, place each battery in an individual LiPo safety bag. Terminals must be protected from contact with metal or other batteries.

• End-of-Life Disposal: Do not dispose of in regular trash. To prepare for recycling, fully discharge the battery (e.g., using a dedicated discharger or salt water bath) and take it to a certified battery recycling center.
