TBS BulletProof 25A ESC

Got my hands on a set of the new BulletProof 25A BLHeli_S ESCs made by TBS.
The ESCs itself feature little TBS logos on the transistors and come in a black resealable packaging.
Although these are just minor details, I do love those little things that TBS adds to their products. Did you know about the Konami Code on their FPV remote called Tango? 😉



TBS ESC Packaging

What you get per package is of course one ESC along with a transparent piece of heatshrink,
2x 18AWG power leads and 2x 22AWG ground/signal leads.
The signal ground goes next to the main ground solder pad, and the signal cable gets soldered to the small solder pad right in the middle. The ESC were delivered with BLHeli_S 16.3, flashed them to 16.5 with Betaflight passthrough on my Kombini FC and copied the factory settings they came with.

TBS ESC Contents

The ESCs are not called “BulletProof” just for fun, they actually have an acrylic conformal coating which makes them harder to solder at first but makes them more withstanding against later abuse. AGAIN: the solder won’t attach like you might be used to at first, but that’s a feature, not a bug 😉

A little how-to-solder tip from RCGroups user “AILERON8”:

“Try using the side of your soldering tip; add a dab of solder to the tip as well. The increased surface area will transfer heat more efficiently. Having the glob of solder on the tip also increases the surface area. It helps to add heat to both the wire and the pad, and if you pretinned both beforehand you should be able to solder these following the procedure I specified above.”

DShot Capability

If you want to use DShot with these ESCs you will have to remove a capacitor,

see the following link for more info:

UPDATE: official TBS how-to on the removal of the specific capacitor
Warranty is lost of course after this modification.

Have a look at the official product page for its Specifications and an optional 220uF 35V Capacitor, which is recommended by TBS for 6S users and high kV/heavy prop combos:

Size-wise they are at 17x25mm which makes them about 20% smaller than e.g. the KISS 24A ESC. Though a bit larger as the Aikon 30A ESC competitor, the TBS BulletProof 25A offers something new to the BLHeli_S market, an “Active Burn Protection”, which is basically limiting the max current at 35A. Plenty enough if you consider that lipos are still todays bottleneck in our powerful little quads.

My latest unfinished build with those ESCs… as always you will find some FPV footage about the whole Setup and the TBS ESCs later on this page… damn winter in Germany keeps me from flying 🙂


For the real “BlackSheep” look I got me some black cables from Banggood 🙂
