The last few weeks we’ve been in the midst of a full inventory transition with some of our product lines, and we apologize to those who’ve had difficulty getting all their kit parts together. This is all wrapping up and there is good news to speak of for those who have been patient.
Grinfineon Controller: Proportional Regenerative Braking.
All of our motor controllers are now running a newer control chip with a customized firmware for proportional regen. We’ve done this in a way that requires no extra hardware. If you have a V3 Cycle Analyst, the regen control is mapped to the otherwise unused 0.0 to 0.8V throttle signal range, giving you full control of the braking force and regen current through the Cycle Analyst. Without a V3 CA, you can use a regular ebrake lever to activate regen, and then use the throttle to modulate the intensity.
We’ve also improved the LED behavior so that you can tell if the controller is operating in sensored or sensorless modes while running, and tidied up the total connector bundle. At the moment, the 20A and 25A controllers are all available with this firmware. The larger 35A and 40A controllers are still in the midst of firmware testing and revisions, but should be available shortly.
eZee 5 LED Console
The latest shipment of eZee kits also includes a simpler 5-LED console for those who don’t require the full details of a Cycle Analyst. This device has been customized for full compatibility with any controller that has a CA plug, whether from an eZee kit or not, and it includes a DC power plug for running front headlights too.
The top row of LEDs show the approximate battery voltage, while the bottom row of LEDs is controlled via the up/down buttons to set the ebike power level via current limiting, much like with a V2 Cycle Analyst. With the 25A eZee controllers, 1 LED = 5 amps, 2 LEDs = 10 amps, etc.
All our recent stock of higher capacity eZee batteries are using Japanese Sony V3 cells as standard. While the Samsungs have worked reliably, their cycle life at higher discharge currents left a little to be desired and we’re hoping the highly regarded Sony cells yield better longevity.
For those who found 10Ah wasn't quite enough, but 20Ah excessive, we've also got the Allcell batteries stocked in a 48V 13Ah pack with power cells, and in 35V 15Ah with regular energy cells.
