The Ultimate Battery Charger

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

 

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. The 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.

 

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.

 

Enhanced Battery Lifecycle

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. 

 

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.

 

Standard Version or High Voltage

Cycle Satiator Universal Programmable Battery Charger:

  • Standard: Cycle Satiator Universal Programmable Battery Charger for 24V-52V Nominal Batteries, 63V 8A Max Output. 
  • High Voltage: Cycle Satiator High Voltage 72V Programmable Battery Charger for 36V to 84V Nominal Batteries, Max Output of 5A or 360 Watts 

 

Cables and Connectors

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 (white wire) is V+, Pin 2 (black wire) is Gnd, and Pin 3 (yellow wire) is for both temperature sensing (with NiCad/NiMH packs) and communications. 

 

There are a host of optional adapter cables from this 3-pin XLR standard to other connector types available: 

 

  • XLR to Anderson
  • XLR to XT60
  • XLR to DC
  • XLR to Rosenberger
  • XLR to RCA
  • XLR to 4 pin XLR
  • XLR to ST3
  • XLR to 3 Pin GX12
  • XLR to 3 Pin GX16
  • XLR to 4 Pin GX16
  • XLR to 5 Pin GX16
  • TTL to USB

 

The XLR to GX adapters allow the Cycle Satiator to charge a variety of electric unicycles, scooters, and skateboards. Most EUCs will require that you use Satiator firmware v1.039, available bundled with the software suite at the downloads link below. 

 

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. 

 

For those looking to wire their own custom adapter cable with a communication port, both signal lines of the TRS communication plug connect to the signal wire of the Satiator via a 1k Ohm resistor, as described in this ES thread post.
