Little Bee Spring 20A ESC with BLHeli_S, DSHOT (2-4S)

Overview:

The all new Little Bee Spring BLHeli_S versions of the popular Little Bee ESCs deliving a "smooth as silk" throttle response. These ESCs now supprt up to 4S LiPos and are capable of handling 20A current with up to 10s 25A bursts.

Don't forget - these ESCs have no BEC so you will still need a 5V power source for your flight controller, receiver, etc. Have a look at the related items below for suitable a suitable PDB and BEC. You may also need wire and bullet connectors unless you intend to solder your motors direct to the ESCs.

Features:

- Hardware PWM - smoother and more responsive motor response
- Solder Pads for motor wires
- Oneshot125, Oneshot42, Multishot & Dshot available - Faster communication between flight controller
- 2-4S support with 20A continuous load and 25A peak (10 seconds)
- Bootloader Enabled - you can flash new firmware and configure settings via USB using the servo cable (requires USB linker or BLHeliSuite)

Specifications:

- Input Voltage: 2-6S Li-Po Battery
- BEC Output: OPTO (you need to power up your flight controller using an UBEC)
- Continuous Current: 20A (Burst Current: 25A for 10s)
- Size: 23.5 x 12mm
- Weight: ~11g (including wires)
- Battery wire length: ~90mm (may vary from time to time)
- Main IC: SILABS EFM8BB21F16, MCU running at 48MHz
- MOS: ALL N FET

Warranty Exclusion: Please note we can't provide any warranty on escs once soldered. Please test your escs in a non destructive manner BEFORE soldering them onto your quad. Removing the motor wires and soldering directly is in our experience risky - many escs get damaged in this way.
