How a custom UAV power system is built
A custom pack is more than a capacity figure. It is a cell, configuration, protection and charging decision that has to survive the mission profile, the airframe and the way the operator actually flies. Our process moves through four stages, and each one narrows the specification before hardware is built.
1. Define the mission
We start with voltage, usable capacity, continuous and peak current, take-off weight, flight time and the environment. Spraying drones see vibration and moisture, survey aircraft need stable voltage for long cruise, and cargo platforms care about cycle life. These inputs decide the cell format and the number of series and parallel strings.
2. Select cells and configuration
Cell selection balances energy density, discharge capability and thermal margin. A 6S pack runs at 22.2 V nominal, 12S at 44.4 V and 14S at 51.8 V, and parallel strings add capacity without raising voltage. We leave headroom on the C-rate so the pack is not run at its limit during climb-out, and we match internal resistance across cells before assembly.
3. Integrate BMS, connector and charger
The BMS monitors cell voltages and temperature, balances the pack and cuts off on over-current or under-voltage. Connector choice, such as AS150U or XT90-S, is matched to the current path and the airframe harness, and the charger profile is set for the chemistry, including high-voltage cells. All of this is confirmed before the first charge.
4. Validate before delivery
Each prototype goes through capacity and internal-resistance checks, a thermal run under representative load, vibration exposure and repeated charge-discharge cycles. Only then does it move to production.
