Yup the tech aero ultra bec and the SAP ultra IBE are the exact same product made by the same manufacturer, this is what I use.

It is different from a normal opto kill in that the ultra bec takes the control signal and ignitionpower voltagefor the ignition from onelead thatcomes from therx. this is opto isolated and filtered.

A normal opto isolation unit takes the signal vaione leadfrom the rx and is opto isolatedand thentakes a ignition powervoltage from a second non isolated lead that is meant to run to a independant ignition battery.

The problem is that if you use one battery and run that non opto isolated secondlead to the shared battery you lose any opto isolation you had! so whats the point.

Im sure ahicks knows the difference so just a heads up for anyone else new to this product

Million dollar question is it required in 2.4ghz.
