5.4. Thermal Rollback
The Cycle Satiator operates with much higher efficiency than standard ebike chargers (94-95%
versus 80-85%). But it also packs twice the power output into a smaller footprint and eliminates
active fan cooling, so the casing will still get quite warm during use. At full output power in a
room temperature environment, it will typically reach about 55-60 degrees Celsius. This will feel
hot to the touch but is not a cause for concern.
We recommend placing the charger in a location where it is exposed to free air in order to help
dissipate this heat. If the charger is in an enclosed space (like a pannier bag), or is used in a hot
environment and starts to overheat, then it will automatically scale back the output power so that
the internal temperature does not get beyond 70 Celsius. This will not affect its ability to
complete a charge cycle, but it will take longer as charging current will be reduced.
5.5. Exposure to Rain
The Cycle Satiator has a sealed enclosure and can handle rain, road spay, and other incidental
water exposure when it is not powered up. However, when plugged in and charging it is
important to be in a dry environment outside the rain. The input and battery connectors are not
waterproof and there is risk of both corrosion and electric shock if powered up in wet conditions.
5.6. Orientation and Vent
In general, the Cycle Satiator is easiest to operate when right side up, but it
will run and function fine in any orientation. The only caveat is that the
membrane vent on the input end of the charger should not be covered in
water, so if it is mounted vertically care should be taken that it is not done in
such a way that water pools around this vent area.
5.7. Thermistor
The 3rd pin of the XLR charge plug can be used in conjunction with a thermistor for sensing
pack temperature. This is recommended with NiMH and NiCad batteries. The charger expects a
thermistor with 10kOhm resistance at room temperature, and a Beta constant between 3800-
4000. This thermistor spec is common in industry with nickel based packs.
5.8. Upgrading Firmware
The firmware and stock profile list on the Satiator can both be updated via an optional USB
adapter plug that connects to the charge port and a computer. Details on re-flashing the
firmware are explained in the help menu of the Satiator Setup Utility, available for Windows,
Mac OS, and Linux from https://www.ebikes.ca/satiator/
