Mini 25A 4-in-1 ESC BLHeli_S 20x20mm 2-4S ESC Dshot600
inc. Silicone shock absorbers
This mini 25A 4-in1 (4x25A) BLHeli_S ESC features the powerful BusyBee2 (EFM8BB21F16) chip that runs at at 48MHz, twice the speed of previous BLHeli_S ESCs. 
This BB2 processor allows the ESC to perform with incredible precision resulting in smooth and responsive power and taking full advantage of the BLHeli_S firmware.
The ESC features BLHeli_S v16.5 firmware pre-installed on them, and upgradable to v16.7 (see actual BLHeliSuite photos). 
They are compatible with PWM, DShot, Oneshot125, Oneshot42, and Multishot protocols.
This 4-in-1 ESC is low profile and compact in size, saving weight and making builds easy. 
The ESC is OPTO (no BEC) and accompanying ribbon cable connects to the flight controller motor signal, and provide VBat out.
Please note: The -ve/+ve (BLACK/RED) leads of ESC ribbon cable provides the full battery voltage to the flight controller. 
If your fc does not have a built in BEC please disconnect the RED +ve wire. 
The kit is designed to be stackable with the standard mini 27x27mm (20x20mm mounting holes) F3 or F4 flight controllers, so includes plastic screw standoffs and nuts.
This small 4-in-1 ESC is perfect for mini 2" and 3" brushless builds.

Please note, Due to the permanent and potentially destructive nature of soldering and connecting to other devices in general, always remember to test electronics first, before attempting to solder to them or connect any accessories.
All flight controllers must be powered up via USB or other non-permanent methods before performing any soldering work and verifying that everything is working via the configurator. 
ESCs can be powered up via crocodile clips.
We will not accept returns or offer refunds for items that have failed to power up or otherwise found to be faulty after soldering and no attempt was made to test and inspect the item before the item was modified. It's expected that, where reasonably appropriate, steps are taken by the customer, such as powering up the device or otherwise inspecting/verifying the components function, to ensure that a device is correctly functioning, before attempting to make modifications.
Each flight controller has a unique device ID which is recorded on the invoice.
