Alltrax AXE vs SR? Answered
I am working with a team at my university of a solar powered boat which is powered using 100lbs maximum of lead-acid batteries. I'd like to thank you for this lesson, it'll be much easier to educate new club members the ins and outs of working with the drive system we have in the future! I've been on the team for years and we used a ton of the same knowledge you have in this class, though we are working with even more powerful motors. Last year we upgraded form a roughly 4KW peak ME0708 to a 16KW peak 5hp continuous Lynch motor, which is still a brushed DC motor but very light and efficient. It was extremely expensive and with a 36V system it basically maxes out the 400A rating on our current controller, the Alltrax AXE 4844.
I was wondering if you would recommend getting one of the new Alltrax SR controllers if we have it in our budget this year? Aside from the current rating issue, the serial to usb conversion needed to program the AXE barely works at all on Windows 10, is officially unsupported after Vista, and from the above it seems the interface is 100x better for the new SR controllers.
[I'm sure you and others may be interested to see out boat from last competition so I'm including a couple images. The entire hull was made by our team with cedar strip wood, and the drivetrain is converted from a gas outboard motor with the mechanical pulley-belt system machined by hand as well :) ]
