New generation of programmable microprocessor electronic speed controllers KAVAN Plus for brushless sensorless motors designed using the latest achievements of the semiconductor technologies ensuring high performance; whilst still being simple-to-use/user friendly. The Plus line ESCs will work great in any of „Sunday flyer“/sporty model planes powered by brushless motors using LiPo/Li-ion/LiFe as well as NiCd/NiMH batteries. The ESC features a powerful switched UBEC ensuring reliable power supply for your receiver and servos. The optional KAVAN LED programming card Pro (sold separately; the same as for the KAVAN PRO ESC line) will make the programming of your ESC a breeze.
FEATURES
- The ESC features a high performance 32-bit microprocessor ARM M4 with a running frequency of up to 96 MHz.
- DEO (Driving Efficiency Optimization) Technology greatly improves throttle response & driving efficiency and reduces the working ESC temperature.
- Suitable for the most of aeroplane model dedicated brushless motors for 3–8S LiPo batteries.
- Compatible with NiCd, NiMH, LiPo, Li-ion, LiFe batteries
- Powerful switched UBEC stabilizer with selectable output voltage 5.0/6.0/7.4/8.4 V up to 10 A.
- Adjustable timing to match your motor perfectly.
- Adjustable voltage protection with selectable cut-off type (soft cut-off/hard cut-off).
- Start-up Modes Normal/Soft/Very Soft to match direct drive as well geared power systems
- Start-up protection prevents the unintentional start of the motor when powered up.
- A number of protection functions: start-up protection, ESC thermal protection, capacitor thermal protection, overload protection, over current protection, abnormal input voltage protection and throttle signal loss protection contributing to safety operation.
- Throttle range calibration to match your radio set signal.
PROGRAMMABLE FUNCTIONS
- Brake Type: Normal brake off, Normal brake on (3 brake force levels selectable), Reverse brake (the forward/reverse run is selected by an auxiliary channel with 2-position switch on your transmitter, the revolutions are controlled by the throttle stick, Linear reverse brake (the reverse revolutions are controlled by a proportional control assigned to an auxiliary channel on your transmitter)
- Brake Force: Brake force adjustable to 60/90/100 % (Normal brake mode only).
- Voltage Cut-off Type: Soft Cut-off: After selecting this option, the ESC will gradually reduce the output to 60 % of the full power in 3 seconds after the low-voltage cut-off protection is activated. Hard Cut-off: The ESC will immediately cut off the output.
- LiPo Cells: The ESC will automatically calculate the number of LiPo cells you have plugged in as per the “3.7 V/Cell” rule if “Auto Calc.” is selected, or you can set this item manually.
- Cut-off Voltage: If set off, the low-voltage protection function is disabled. If on, the protection voltage threshold is selectable at 2.8 V/cell, 3.0 V/cell or 3.4 V/cell.
- Start-up Mode: This is used to adjust the throttle response time of ESC acceleration from 0 % to 100 %. Normal/Soft/Very Soft correspond to approximately 200 ms/500 ms/800 ms respectively.
- Timing: Adjustable to 5/15/25 °.
- Active Freewheeling (DEO): This item is adjustable between “Enabled” and “Disabled”, and it is enabled by default. With it enabled, you can have better throttle linearity or smoother throttle response.
- Search Mode: After selecting this option, ESC will drive the motor chirping prompt when the throttle is kept at 0 % and continue to do so during the set time.
- BEC Voltage: Selects the BEC output voltage 5.0/6.0/7.4/8.4 V.
PROTECTIVE FUNCTIONS
- Start-up Protection: The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount is less than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move the throttle stick back to the bottom position first and then restart the ESC.
- ESC Thermal Protection: The ESC will gradually reduce the output to 60% but won’t cut it off when the ESC temperature goes above 120°C (soft cut-off mode)/the ESC will shut the motor off (hard cut-off mode).
- Throttle Signal Loss Protection: When the ESC detects a loss of signal for over 0.25 seconds, it will cut off the output immediately. The ESC will resume the corresponding output after normal signals are received.
- Overload Protection: The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value.
- Low Voltage protection: When the battery voltage is lower than the cut-off voltage set by the ESC, the ESC will trigger the low-voltage protection. If the battery voltage is set to soft cut-off, the battery voltage will be reduced to a maximum of 60 % of the full power. When set to hard cut-off, the output is cut off immediately.
- Abnormal input voltage protection: When the battery voltage is not within the input voltage range supported by the ESC, the ESC will trigger the Abnormal input voltage protection, ESC will drive the motor to sound the alarm.
Tip: Turning the ESC on for the first time: Perform the throttle range calibration following the instructions in the manual. Only then you can use the ESC normally or you can set the programmable parameters using your transmitter or the KAVAN LED programming card PRO.

Good looker but terrible performance
Color: 2-Speed Rechargeable Set with Charging Base
I purchased the product and the base would not attach from the charging module. This is their big selling point. I requested a replacement and sadly the replacement was of the same batch run as the original soo…. Yeah that base would not detach. There are videos showing how easy it is to detach base from charging module. Not theses units. Circle Joy customer service is an @gmail.com. They said base is not designed to be removed frequently. I reminded them the separation feature is their highlighted feature. I was just looking for a base. Circle Joy said no…. If I do not like either unit just return them to Amazon.???? In the meantime, after maybe a dozen grinds, the original unit quit grinding normally and would barely grind at all. I shook it out and it worked again but doesn’t sound right. Two takeaways: 1) Poor product quality. 2) I am sooo done with trying to work with Amazon on replacement items. Save yourself a tone of aggravation and just return the order and reorder if you dare. Otherwise good looking and heavy feel and works great about 10 times. Too bad so sad. Now I have this huge return hassle with Amazon.

Really Effective Utility
Color: Black/Black
I’m extremely impressed with this Electric Salt and Pepper Grinder Set! From the moment I started using it, it made seasoning meals so much easier and more enjoyable. The one-touch operation is incredibly convenient, especially when cooking with both hands occupied. The grinders are powerful, consistent, and produce the perfect grind every time.
I also love the adjustable coarseness settings, which let me switch from a fine grind for everyday dishes to a coarser texture for steaks and salads. The build quality feels sturdy and premium, and the modern design looks great on my kitchen counter and dining table.
Overall, this grinder set combines style, convenience, and performance perfectly. It’s a fantastic addition to any kitchen and would make a great gift as well. Highly recommended!

A Small Luxury That Makes a Big Difference
Color: Black/Black
I absolutely love these salt and pepper grinders.
They’re sleek, modern, attractive on the table, and honestly much nicer looking than I expected for the price. They even come with their own little caddy, which keeps everything neat and organized and looks great when guests are over.
What I love most is how easy they are to use. You simply press a button and instantly get perfectly ground salt or pepper. No twisting, no awkward grinding with two hands, no effort at all.
I especially love this for pepper because I use a lot of it when cooking things like soups, lentils, and large meals. Before, hand grinding would make my arm tired, and sometimes I’d end up with uneven chunks of pepper. With these, the grind is smooth, even, and consistent every time. You just hold the button and move it around — quick, simple, and efficient.
They also hold a generous amount of salt and pepper, so you’re not constantly refilling them every few days.
Honestly, they make cooking easier, they look beautiful on the table, and they feel much more expensive than they are.
Excellent purchase and a fantastic gift idea.

Great idea, great product
Color: Black/Black
I’ve been using this electric salt and pepper grinder set for a few weeks now and it’s one of those kitchen upgrades you don’t realize you needed until you have it.
the top refill design makes it quick and easy to fill with course salt or peppercorns. It holds a good amount so youre not constantly refilling it
I really appreciate that these grinders are rechargeable, and therefore a little more eco friendly. The battery life has been solid so far, and I haven’t had to worry about it dying mid-meal.
Using it is super simple, It’s truly one-hand, one-button operation, which makes a big difference when you’re cooking. You can grind seasoning while stirring or holding a pan with your other hand. There’s also an LED light that turns on while grinding, so you can actually see how much seasoning you’re adding—small detail, but surprisingly helpful.
There’s a small dial underneath that adjusts the grind size from course to fine. and the salt and pepper come out in a really uniform, consistent grind.
Overall, the pros—easy refilling, rechargeable design, adjustable grind size, uniform results, —definitely outweigh the cons. It’s a practical, stylish upgrade that makes everyday cooking feel just a little easier and more polished.

Great Quality, Easy to Use, and Looks Sharp on the Counter
Color: Black/Black, Color: Black/Black
I’ve been using this electronic salt and pepper grinder set for a bit now, and I’m honestly really impressed.
First off, the one-handed operation is a game changer. Just press the button and you’re good to go—super convenient when you’re cooking and juggling multiple things. The grind is consistent, and the adjustable coarseness actually works well (not just a gimmick like some others I’ve tried).
The build quality feels solid, and I like the clear chamber so you can easily see when you’re running low. The LED light is a nice touch too—it’s subtle but helpful, especially when cooking in lower lighting.
Aesthetically, they look clean and modern. The black finish with the matching base makes them look great sitting on the counter instead of having to hide them away.
Battery life has been good so far, and refilling is straightforward without making a mess.
Overall, these are a big upgrade from manual grinders—more convenient, better control, and they look great. Definitely recommend if you cook regularly or just want something a little nicer in your kitchen setup.
