Can R-net controllers handle 36 volts if I had a OEM dongle to program it with? I ask because I have a Permobil M300 that I want to build a lithium battery for and if it will go 36v why not!
And what are the most powerful motors that can be acquired, i'm building a strictly off road chair so want the best motors for the job, this will also be 48v or more and use the Robotek controller.

No. Its designed for 24V lead, or up to 29.6V when charging, with a typical 32V limit before you get errors. The ACTUAL short term max voltage is coused be gegenerative spikes up to around 32V and so the controller has a 32 to 35V extreme limit. Best to use 8S LiFePO4.And what are the most powerful motors that can be acquired, i'm building a strictly off road chair so want the best motors for the job, this will also be 48v or more and use the Robotek controller.
Whats you definition of power?
Watts determine what the motor can safely HANDLE CONTINUOUSLY. They do NOT tell you how powerful a motor is regarding torque.
Its like this. Provided the motor can pull more Amps than the Roboteq can provide, then ALL motors will give the exact same torque at the output shaft at the same max speed rating. So if 2 different motors run at 6mph, and both are limited to x Amps by the roboteq then as long as both are equally efficient (most are quite similar) then both will produce the same amount of stall torque. And the same speed. Motor watts doesent enter into this.
That is unless you exceed the average watts rating and melt something. So higher watts will protect against this. Its really just a measure of how fast it can cool... So. does that help?
Doubling the volts means that you go twice as fast. Torque remains the same.
Unless you change the GEARING and half it. So now it goes at double the MOTOR speed but the same road speed, but has double the torque. With the same motor, and the same current limit.
Does that help?
On the motor VOLTS = RPM. and AMPS = TORQUE.
So, I'm looking for Torque. But it sounds to me like that is controlled by the gearing and the controller.
I have a pair of 4 pole motors from a heavy duty 4mph invacare arrow 3gar base. I had planned on just using those with the 90 amp MK6 controller, but since I have acquired the Permobile M300 I plan on going full off road with it.
I will get a robotek to use and set it up with 48V. I think that it will be just fine with those 4 pole motors and 48v. All I want the extra torque for is primarily the ability to climb a hill, otherwise it will be nice to go faster.
Unlimited control
R-net, our most advanced control system, in combination with Intelligent Control System (ICS) raises driving performance, safety and coordination of functions to a whole new dimension. From the start R-net/ICS has been designed to control and monitor a variety of functions and information. The system has wide expansion capability and almost unlimited potential. R-net/ICS uses advanced technology to link the user's needs and intentions with the chair's performance and capabilities. All electrical seat functions can be coordinated with the chair's driving characteristics and programmed to suit individual needs.
High resolution graphics and large screen icons ensure ease of use and availability. Driving and controlling the chair and its functions are now even simpler and more natural. R-net/ICS is also the safest and most reliable control system we have developed. Naturally it can be adapted to suit all forms of advanced disability aids.
Features
• High expandability and capacity for handling advanced multiple functions
• Improved driving precision
• Clear display with high-resolution graphics
• Large, clear screen icons
• Extensive programmability for adaptation and integration of electrical functions, memory modes, favourite positions etc.
• Facility for numerous advanced combinations of seat functions and mobility
• Useable on all new Permobil models

Yes, it should work fine, mine is the same part #.

Where did you get it from? Can you claim import tax back? VAT maybe, though it'll be a struggle after the event.

HMRC let you claim after purchase if you know code. Importer not helpful providing codw so hence coming here. The Trade Tariff Code tool is so ambiguous and non specific i guess i'll have to use codes related to wheelchairs accessories in general!

Proving the device is 'wholly designed', etc., for disabled people is always the stumbling block.

Thanks for that. Turns out that ups are being total legends and by sending me an email that I have to return signed stating that this item is for disabled use only and they will waver the import tax fees so I don't have to pay the driver COD if the they emailed back the waiver code in time.
if not I can claim it back via UPS instead of HMRC without the tariff code.
