12A UBEC: The "Please Don't Fry My Servos" Power Module

Look, we know why you’re here. You’ve got a massive 14S battery that could probably power a small village in the Cotswolds, and you’re trying to connect it to a receiver that has the structural integrity of a wet biscuit. You need a regulator that doesn’t double as a smoke machine. Enter the UBEC 12A—the heavy-duty babysitter for your high-voltage electronics.

Why You Want It

Most BECs give up the ghost when they see anything over 6S. This one laughs in the face of 14S LiPo packs. It takes that raw, unbridled DC chaos and turns it into a silky-smooth 6.0V to 9.2V output. It’s got a metal housing because heat is the enemy, and we know you're probably going to tuck this into a spot with zero airflow because you like to live dangerously.

Specs

  • Input Voltage: 3~14S LiPo (Because 6S is so 2019)
  • Output Voltage: 6.0V / 7.2V / 8.0V / 9.2V (Adjustable via DIP switches—yes, physical switches you can actually touch)
  • Continuous Current: 12A (Enough to feed even the hungriest servos)
  • Burst Current: 24A (For those moments when you panic-roll)
  • Efficiency: >90% (Less heat, more flight time)
  • Dimensions: 48 x 33.6 x 16.3 mm (Smaller than your ego after a crash)
  • Weight: 47.8g (Lighter than a pack of UK crisps)
  • Input Connector: XT30 (Small, reliable, slightly annoying to solder)

In the Box

  • 1x UBEC Power Module (The main event)
  • 1x XT30 18AWG Cable (Juice delivery system)
  • 1x DuPont 3P Cable (The bridge to your receiver)

Compatibility

Works with high-voltage servos, heavy-lift hexacopters, industrial drones, and that over-engineered RC lawnmower project you've been working on for three years. If it takes 3-14S and needs 12A, this is your guy.

Highlights

  • DIP Switch Control: No weird software or "hold the button while the LED flashes three times" nonsense. Just flip a switch.
  • Metal Shielding: Reduces EMI, so your FPV feed doesn't look like a 1980s TV during a thunderstorm.
  • Quad-Output: 4-channel parallel header pins because one output is never enough.

Notes

This is a synchronous step-down regulator. That means it takes high voltage and makes it low. If you try to do the opposite, you'll be buying another one very quickly. Also, keep the DIP switches away from curious fingers once set.

Disclaimer

Don't set it to 9.2V and plug in a 5V receiver. We won't judge, but your receiver certainly will (with fire).

Still Here?

If you’re still reading this, you’re either a crawler bot or someone who actually cares about power redundancy. Either way, stop overthinking your power loop and just get a BEC that won't melt. We're based in the UK, so shipping won't take an eternity. Add it to the basket already.

Fantastic Boots!
Size: 8.5, Color: Redwood/Gum 10
Completely satisfied with these boots. True to size, well made, comfortable from the get-go; not break in needed. Waterproof- really. The Red Suede has withstood a nasty winter season & still looks great. Good traction. I like the ankle height which looks good with long, mid length pants & leggings. I love the easy slip on/off aspect..made getting ready for dog walking easy. I 100%recommend!

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!
