Powerbox ESC Backup 5117
- The back-up battery solution for all current brushless speed controllers with integral BEC
- The ESC Backup enables the user to produce a reliable, redundant receiver power supply using an existing speed controllers BEC power supply and an auxiliary battery. The ESC Backup has two inputs from the speed controller: one for the PWM output, the other for telemetry - if present.
The signals are passed through 1:1, while the current-bearing conductors are de-coupled from the support battery, which is connected on the underside. The result is that any failure, or even a short-circuit in the speed controllers BEC circuit, has no adverse effect on the receiver power supply. The ESC Backup can handle currents up to 20A, and is supplied ready to install, with all connectors and cables.

Simple and Super Useful
Color: Black Frame
This tray is great. It looks really nice on my desk and gives me one easy spot to drop everything—phone, wallet, keys, sunglasses, glasses, and whatever else I’m carrying that day. Keeps things organized and adds a clean look to the space.

Great magnets and sturdy hooks
These are great hooks! I needed something quick and easy to move around - these fit the job perfectly. The magnets are strong enough to securely hold the ropes and cables I needed to hang, and yet we can move them around as needed. Great purchase!
