What to check before you buy
- Continuous current
- Compare continuous and burst current with your motors at full throttle.
- Cell count
- Check the supported battery range against your pack.
- Mounting size
- For 4-in-1 boards, check 30×30 or 20×20 spacing and the connector to your flight controller.
- Firmware version
- Ask which AM32 version and target the ESC ships with and how it is updated.
- Telemetry
- Check current sensing and ESC telemetry support for your flight controller.
