Cycle Satiator

From the labs at Grin Technologies for ebike riders around the world comes a programmable universal fast charger for all types of battery packs.


The Cycle Satiator® defines a whole new class of ‘smart charger’, one that gives you, as a user, dealer or OEM, full control to set up the optimal charging scenario for your batteries.

Design Features

Universal Compatibility

The Cycle Satiator is not limited to charging a specific battery type. Instead this one charger model can be configured for virtually any lithium, nickle metal hydride, or lead acid battery pack with a full charge of 60V or less.


Informative Display

A large and bright OLED display screen shows all your realtime charging statistics; you can see the total amp-hours and voltage along with a clear graphic indicating the approximate charge in the pack.


Impressive Power Density

At almost 0.5 watts / cm3, the Cycle Satiator packs 2-3 times more power per volume than most other chargers available.  This translates into big league charging currents in a portable size device.


Fan Free Efficiency

The power electronics were carefully designed to reach 95% efficiency at full load, eliminating the need for a fan to get rid of waste heat and keep things cool. no more buzzing fan noise and no risk of charger meltdowns if the fan fails.


Sealed and Watertight

A gasketted enclosure and connector design strategy keeps the charger electronics protected in the face of rain, road spray, dust storms etc.


Compact and Narrow Size

The charger is less than 5cm high and 8cm wide, allowing it to fit easily in a saddle bag, under the rear rack, inside a frame triangle, or screwed to a chassis.


Power Factor Corrected

AC input runs from 100-240v, allowing for worldwide operation without any voltage selection switch, and features a 0.99 power factor which will please your utility grid too.


Onboard Installation

The rugged, compact, and fan-free design allows the charger to be permanently mounted on the vehicle without risk of premature failure from vibration or exposure.

Seriously Fast Charging

With a 360 watt power output, the satiator can charge your batteries in half the time of typical 4amp ‘fast’ chargers.  It delivers up to 8 amps with 24 and 36v packs, and 7 amps with 48v packs.


One Charger For All

No need for a different charger for each battery type, the satiator can be programmed to work correctly with almost any packs on hand. select from one of our common preloaded profiles or make your own custom charge profiles.

Quick Select

Have anywhere from one to dozens of preconfigured charging profiles active, enabling you to readily switch between output modes with just a quick button press.


Satiate for Enhanced Cycle Life

Most lithium batteries are capable of vastly improved cycle life if they are not fully charged to saturation all the time, but at the expense of reduced range.

With the cycle satiator, you can program your primary profile to give an 80% charge, and have a secondary profile that does a 100% charge when you need full range. Then have the best of both worlds, a battery that lasts thousands of cycles but still goes the distance when you need it. For more details, read here.

Future Proof

The firmware can be upgraded in the field, and along with the flexible custom profiles this means your cycle satiator is ready for whatever batteries the future has in store.


Designed in Canada

The engineering and design team behind the satiator are avid ebike users with years of experience in electric vehicle technology. This product is the charger they always wished they had, and we hope you feel the same way too.


For OEM and Businesses

In addition to electric bike enthusiasts, this charger is of great value to ebike businesses that need to manage a range of battery packs, and for oems wanting to distinguish their vehicle with a rugged and modern full featured charger.


This device is CSA, UL, and CE listed, meaning it has passed rigorous safety and reliability tests, and can be legally resold in most jurisdictions.

Cables and Connectors

The Satiator uses the common IEC connector for the AC input, which is the familiar plug used on computers and many other devices. We include the matching cable for North American outlets, but do not currently have a supply of cable standards for other countries. Being such a common cord you should have no problem finding one around the house or from any electronics store.

 Satiator AC Input Cable

The DC output is connectorized via the waterproof Singatron 2ct3002-w03400 jack. Each Satiator includes a 1m long DC ouput cable that is terminated in a 3-pin male XLR plug. This is a fairly common connector for ebike battery packs, and is used by Allcell and eZee batteries as well as many turn-key electric bikes and scooters.  Pin 1 is V+, Pin 2 is Gnd, and Pin 3 is for both temperature sensing (with NiCad/NiMH packs) and communications. 

Singatron DC Output Jack Satiator XLR Pinout

 There are two optional cables that can be included with the purchase as well: 

XLR to Anderson and TRS Adapter Cable An XLR to Anderson adatper converts the power leads to a pair of red and black anderson powerpoles, allowing you to charge a battery via this connector which is commonly used on the pack's discharge wire.  It also brings out the signal wire to a TRS jack.
Zener Protected TTL->USB for Satiator Communications The TTL->USB cable is used for connecting the Satiator to a computer's USB port for updating firmware and reading/writing new charge profiles. This is the same 3m long cable used by the Cycle Analyst, but with some additional circuitry to protect against high voltages present when it is first plugged in


If you already have a TTL->USB cable for a CA, then you can use that on the satiator instead, but it is essential to plug the TTL->USB cable into the charger before the charger is powered up from the wall. Otherwise, the CA's TTL->USB c circuit can be damaged.  The device sold with the Satiator is not vulnerable this way and can be plugged in any order.  It requires the XLR to Anderson adapter.

User Manuals

Satiator User Manual for V0.9X Firmware
Older Prelim User Manual (for V0.8X Firmware)

To upgrade your firmware from a V0.916 or earlier, please download the V1.0 software above, extract to a folder, and run "Satiator Software Suite.exe". Place your Cycle Satiator into bootloader mode and be sure the TTL Serial cable is plugged into your computer. Do not press the green "Connect " button, but rather click on the File ->  "Update Satiator Firmware..." menu item. Browse to the included "v1.014.satiator" firmware file, check the "Overwrite Profile Data" checkbox, and click the "Upgrade Firmware" button. This will erase your old profiles, and require you re-enter any custom profiles. Upgrading from V0.9x to V1.0 requires that you erase your previous profiles while uploading the firmware, as they are no longer compatible with the new format adopted by V1.0.  To repeat, when upgrading from V0.9x or earlier firmware, please be sure to click the "Overwrite Profile Data" checkbox when upgrading, as shown below, otherwise the reflashed Satiator won't have any profiles present.

Satiator "Overwrite Profile Data" Checkbox

Further updates of satuatior firmware are accessible directly from the satiator software suite. So if you click "File->Check for new Firmware..." then the software will automatically find and download the most recent build. You then upgrade the firmware on the Satiator by clicking "File->Update Satiator Firmware...".  The current release is V1.014 (Jun 1, 2016).

Online Charge Simulator

We've also produced a web application for creating custom charge profiles with the Satiator and simulate the charge times of various battery packs. This is especially useful for configuring custom partial charge profiles in order to improve the cycle and calendar life of your battery.
