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. Our standard 48V 8A model will charge packs with up to a 63V max charge voltage (15s for lithium), while the 72V 5A model will work all the way to to 103V max (24s lithium).

 

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.

Benefits

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.

Certifications

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 a host of optional adapter cables from this 3-pin XLR standard to other connector types that can be included with the purchase: 

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.
3 Pin XLR to XT60 Satiator Adapter Cable An XLR to to XT60 adatper, commonly used with RC style battery packs. We have this available both with male and female XT60 plugs a there does not seem to be a consistent gender standard used by battery vendors. 
3 Pin XLR to DC 5.5 x 2.5mm Adapter Cable An XLR to DC Jack allows the Satiator to charge most frame mounted batteries, like the common "shark" or "dolphin" packs. While the 5.5 x 2.5mm DC plug used on our adapter is rated for 7 amps, most of the DC jacks used on these batterie are of low quality and should generally not be used at more than 4 - 5 amps of current. 
3 Pin XLR to Rosenberger Satiator Adapter Cable The XLR to Rosenberger lets you charge many european ebike batteries that have adopoted this magnetic battery connector popularized by the Energybus standard. Although the full specificaion calls for CANbus communication on this plug, this adapter cable only has the + and - power leads connected.  
3 Pin XLR to RCA Plug Satiator Adapter Cable The RCA style plug is commonly used on older generation rear rack mounted batteries such as those sold by Golden Motors. Like the DC jack, it is not a connector style commonly associated with high currents, so care should be excersized when using this at more than 4 - 5 amps. 
3 Pin to 4 Pin XLR Adapter for Juiced Bike Batteries The 3 pin to 4 pin XLR adapter cable is specfically made for the Juiced Riders ODK cargo ebikes. These batteries use a 4 pin plug, but simply double up on the pins so that there are two V+ and two Gnd pins. The new 2017 battery series from Juiced are compatible with full 8A charge currents. 
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

 

Each of these adapter cables also has a TRS jack on it (commonly used for audio headphones) which allows you to connect the Satiator to a computer using the USB->TTL communications cable.
