The FETtec Spike Absorber uses well-chosen TVS-Diodes to prevent the connected components from huge voltage spikes. The Spike Absorber is meant to be used in addition to an electrolytic capacitor. The capacitor can be mounted directly on top of the board.

It will take care that the voltage doesn't rise above a specific level. Which means it absorbs energy once the specific voltage level is reached.

On electrical power systems using brushless motors, ESCs and LiPo batteries, high current and voltage peaks are common. The most known way to keep them in areas where they don't damage items that are connected to the battery is the usage of capacitors. Capacitors dampen any movement of the voltage. They store energy if the voltage rises and supply it when the voltage falls. But in some cases, there are very short but high voltage spikes where capacitors are too slow. These spikes are mostly very short and appear in the area of some nano – microseconds, but can easily be double or triple the normal battery voltage. 

Most consumer electronics can survive a lot of these spikes, even if they are over their normal voltage rating, but if the spike is too strong, or it happens over a longer period, voltage regulators, capacitors and FETs can be damaged and fail. The Spike Absorber will absorb the energy of these spikes before they get in areas where gear might get damage.

Review highlights

Reviews

Dampens voltage spikes really well

"Keeps your voltage lines clean and dampens voltage spikes really well"

— Kiet P. (5/5)

Absorbs spikes

"I don’t know whether I’ve ever pushed it, but I’m glad it’s there"

— Ben W. (5/5)

"Protect to stuff"

— Rhett (5/5)

Fettec spike absorber

"Dues the job"

— Kevin H. (5/5)

always use with fettec esc

"always use with fettec esc"

— Jason W. (5/5)

Stops the pop

"Do you not like the massive POP a 6s battery creates every time you plug it in? This will make it less of a weld and more like a regular plug-in that you're used it."

— Curtis H. (5/5)

Good peace of mind for DJI O3 air unit

"So far it's been good. No video nor other electrical problems that I can tell."

— Nguyen D. (5/5)

I use these on 99%of my builds.

"I did 2306.5 1960kv, 2207 1960kv no problem. One has just a 470uf50v cap, others have all have spike absorber and a 1000uf35v Panasonic fr. They do work great."

— Brandon W. (5/5)

I just use these

"just use it!"

— Isaac M. (5/5)

Tvs diode

"I run these religiously on ever single build big or small must have !"

— Erick M. (5/5)
