This is a very pregnant question… and I yam an engineer
Therefore I offer the short answer: No
And then there’s the compete answer
… which is perhaps driving wildly off topic… although I like a good yarn, so here it is.
To begin: I have used several controllers in the past provided by a handful of suppliers – and they are nearly all the same in terms of origin and design (though not of throughput). I am trying to think of the count that I have gone through… off-hand I’d estimate 8 since 2009. The majority have been Lyen 12-FET Controllers.
Sidebar & small disclaimer: As a curious person who likes to tinker and experiment, sometimes those experiments go awry – with sparks
There’s nothing wrong with the controllers – I’m just trying to push the envelope with what I’ve learned on ES and share in discoveries – however well they went or not… And I wish not to take away from the value or quality that is provided by our good suppliers. I have personally met Edward Lyen and think of him most kindly and with great respect. He provides a product of which I understand with trusted familiarity to use as a base for modification.
For this 2011 Road Trip, the Lyen Extreme Modder 12FET controller
was used. It is based upon a standard design that is well-documented by a cadre of ES-greybeards, with me chiming in late to the party. Every controller that I have owned before moving to Lyen-models required the “R1” mod to improve or upgrade the voltage-carrying capacity. Essentially – Battery Voltage (VBatt) comes into the controller and is divided by the MOSFETs into digital 3-Phase by the Microcomputer & associated discreet components. The “Voltage” going into the controller is gated by two factors: MOSFETs & the first Voltage Regulator managing the 15V rail before the 5V logic.
When you purchase a controller, it used to be that we had a choice between 75V and 100V maximum output, though today most common ebike controllers for BLDC direct drive motors are capable of 100V – gated by the MOSFETs, therefore we no longer have to concern ourselves with 50% of the challenge.
The other half of the problem is knocking down the VBatt coming into the primary Voltage Regulator. On most controllers this is managed by the resistor complex is called “R1”. Low-powered boards would have just one (relatively) big fat resistor coming off the +VBatt leg before going into the input of a LM317 VR. Off-the-shelf, most controllers can handle 36 to 48V because they use a variant of the LM317 component that can take +40V differential, although late models now are supplied with a +60V differential (or perhaps a different management circuit altogether) which enables them to handle up to 75 Battery Volts (or more). In the old days we would modify the value of R1 (et al) to allow the use of larger voltages, although as hinted
this is no longer a problem if you purchase your controller from the right supplier.
Longwinded, it is now after explaining this that I can answer your question:
E-Bikekit does not make controllers, just like they do not make hub motors; they are a reseller
. I do not know off-hand what type of controller they are selling; if you own an E-Bikekit controller I would search ES to find out more about that particular unit and how to modify the voltage capacity, though I’d wager it is an R1 mod of some sorts… don’t quote me.
IMO tinkering with R1 is passé
; there are better models to choose from at a reasonable price that have better standard features. I tend to look for Ebrake, 3-Way, Cruise, CA, and the programming adapter on top of the mainstay list – and these can be found easy enough in the Marketplace on ES
That said, no one makes a Kingfish
model that is ready for bear. There is lots, Lots, LOTS of room for improvement!!! But we take what we can get and do the best we can with stone knives and bear skins.
One last thought: If you decide to replace your controller, take a close look at the connectors and try to match up one that will mate with your existing equipment, otherwise you’re in for another tedious mod… not that it ever stopped me.
