288 Wh Custom Battery
16 Samsung INR21700-50E cells in a hand-built 4S4P configuration. Designed for endurance, built for reliability.
Samsung INR21700-50E
The Samsung 50E is a high-energy 21700 cell rated at 5,000 mAh with 9.8 A continuous discharge. In a 4S4P arrangement, 16 cells deliver 14.4 V nominal at 20,000 mAh — enough energy to fly 100+ km on a single charge.
Each pack is assembled by hand: cells are sorted by internal resistance, spot-welded with nickel strip, and enclosed in a custom-fit housing that slides into the fuselage payload bay.
Battery Pack
Pack Design
Spot-Welded Nickel Strip
Each cell is connected with pure nickel strip, spot-welded for low-resistance joints that maintain performance across hundreds of charge cycles.
Integrated BMS
A battery management system monitors individual cell voltages, prevents over-discharge, and ensures balanced charging across all 16 cells.
Balance Charging
The 4S4P configuration charges through a balance connector, equalizing voltage across all four series groups for maximum pack longevity.
Thermal Management
Cell spacing and pack geometry are designed to allow passive cooling during high-power VTOL phases, keeping cell temperatures within safe limits.
Power your missions
The Operator and Enterprise packages include a pre-built 4S4P battery pack, ready to fly.
