# **Exciting News – Sequre is Developing a Waterproof ESC!**
Sequre is currently working on a **waterproof ESC** designed specifically for **electric hydrofoil boards** , and this could benefit the entire community.
## **Confirmed Features:**
- **Waterproof** design
- **10AWG power lines**
- **BEC: 5V, 1A**
- **Signal lines:** Signal, Telemetry, 5V, GND
- **Hardware current protection**
## **Potential Features (Pending Confirmation):**
- Enhanced hardware current protection
- Gradual ramp-up for smoother power delivery
- Battery disconnect function
- More accurate RPM output than standard telemetry
- 14S voltage support
## **Community Input Needed:**
The **length of the motor and battery power cables** is still undecided. What length would you suggest?
## **Technical Overview:**
This ESC follows the **same control principle as the 12200** , but with significant improvements:
- A **customized MOSFET** with better overcurrent protection
- Possible **power IC upgrade** for higher voltage and overcurrent resistance
- Optimized **PCB layout** for improved performance
- While functionally similar to the **12200** , this ESC is specifically **engineered for electric hydrofoil boards** , rather than drones.
## **Get Involved!**
Vote for the features you want, share your suggestions, and provide feedback. The **Sequre team is actively following this thread** and is open to requests. This is a unique opportunity to influence the final design!

The following things would be nice.
- CAN connectivity
- Passively cooling the ESC (no water pump needed)
- As small as possible size.
- LISP, or any other language programming (like VESC)
- Higher voltage option (S16?)
… more will follow

Passive cooling and FETs only on one side.

Sounds great!.
If it could keep the same form factor/size as the 12200 esc, while also having a built in BEC and support to 14S that would an awesome drop in replacement for that type of esc (the existing 12200, the Xcross, and the Flipsky ESC are all pretty much the same size depending on the heatsink used). What firmware will it be running (AM32?) - with BLHeli32 no longer supported it would be great to see some more options running alternative firmware instead of just using unsupported/test BLHeli firmware.
As for cable length I’ve always soldered my own cables on them - if you can pre-tin the solder pads that saves people having to remove cables (if they want to use something else), but makes it easier to solder their own cables to the ESC.
Probably the biggest thing with this type of esc is the quality control during assembly. Most escs this size (with the odd exception) have fairly high failure rates as you’ll see in the forum. If this ESC doesn’t blow up very often you’ll end up selling plenty to people in this forum.

Yes, I also hope they manage to achieve both a BEC and 14S support within that form factor.

I’ll share a detailed write-up on my experience with the 12200 later. Regarding firmware, I’ve tested Escape32, AM32, and BLHeli32 (since they offer these versions)—though only on the bench. So far, BLHeli32 has been the only one I could properly tuneMy two cents are that these features likely belong in VESC…

All the waterproof ESCs I’ve seen online have cables coming from the inside, likely to prevent any electrical contact with water. With exposed pads, you’d need to epoxy them or use another sealing method, which might actually be the right approach since it allows users to customize their cable length.

If it’s encased in aluminum like the 12200, I don’t think it really matters which side the MOSFETs are on.

Yes it does. If you cool one side, the fets on the non-cooled side are less efficient and more likely to overheat first.

I absolutely agree. FETs on two sides don’t make sense for passive cooling in my opinion. I love my two Kontroniks, which only require cooling on one side. It makes everything much simpler and more efficient.

It’s best to use an aluminum PCB and actively cool it. This is the proper approach, as seen in VESC, though it comes at the cost of increased size.

It’s best to put the esc near the mast mount ( US rails) for the cooling … So in the water.

Having just built a setup with Sequre 122200, my input (possibly more consumer oriented):
- motor cables long enough at least to escape the waterproof housing, ideally long enough to reach a tow boogie motor… (30-60cm?) with some appropriate bullet connectors. You can always cut them.
- appropriate 14S battery connectors, you can always remove them.
- pre-tuned so no need to connect to a computer to configure.
- ship it built into a camdenboss box, with a heatsink mounted through the side and 3 x cable glands already installed! 😅
Personally, if you could connect a motor and RX to it without soldering or gluing a single thing, I think you expand the potential appeal. There are lots of people interested in this but don’t know what connectors to buy, what cable, how to make a waterproof box etc

If they are developing a waterproof controller, they should take the time and effort to put on waterproof connectors and then sell the input connector with it. That way its super simple for anyone to use it.

This is a bit harder, especially if it’s a FOC based controller. But they could ship is configured to a specific motor that’s most common.

No one would get this. Cambdenboss is gen1 assist level. In the near term there will be way better options than using a Cambdenboss.
What they should do is provide a sensible way to fit/attach it to a cutout in either a board or housing. No one else on the market does this and it would really separate it from the rest.

Say more?
Agree generally, these were just ideas for things that came to mind on the road to getting a tow boogie that I’d happily have skipped

Yes, I think this is worth doing. Set to 140 kv so that it will work without connecting..

## Updates on the development
Features BEC:
Suggested wire length options:
All the inside glued/potted as one.
It feels solid - like a brick.

Any idea on release date for this? Wait for this or buy the 12200 if needed soon?

I got this response:
“It is expected to be released in one month. In case of special circumstances, it may be postponed”

Cool, I think I will wait until this comes out. Thanks for the update.
