I now understand why it states that it can do 60-80A. It can do that at lowest voltage ~21V which is 1400W I highly doubt it could do it at 60V. As they don’t mention wattage and only current
300A with that case is like a joke Our solid bar of aluminum is hot at 150A so I would like to see it even do 100A but of course, at low voltage, it’s not big wattage 20 * 150A is 3kW same as 60A at 50V
So FocBox Unity run fork of vesc-tool and fork of vesc firmware? Where is the source codes and schematics
Why are you talking about input voltage in regards to FETs heating? The throughput wattage doesnt matter for heat generated. All that matters is voltage drop across fets and current through them during. This will be a function only of current and FET on resistance not voltage.
If a fet is 60v rated it will do the same max amps at 20V as it would at 60V. The whole point of higher voltage batteries is more wattage through the board without extra heat.
Like they released BLDC-Tool / Firmware (running inside shipped focboxes) source code?
The GNU GPL demands that as soon as you distribute GPL licensed software in executable format you make available the “complete corresponding source code”. The GNU GPL also contains a definition of this term:
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable.
You are welcome to continue throwing negativity while we focus on creating an awesome product that is going to improve the eskate experience while reducing cost and giving back to the community. This entire focus on focbox firmware open-sourcing is little more than a smear campaign, the firmware is unchanged from existing open-source repositories. The point of open sourcing is to make updated/improved code available to the community for integration in other projects, the focbox code is already available in open source repositories. The unity firmware which I am developing will contain many new and interesting tidbits which, as the license requires, will be open sourced. To do anything else would violate the spirit of open source license. It is my sincere hope that my work will be used to improve other vesc-inspired designs.
Back to the topic of this thread, it is good for people to acknowledge when they make incorrect statements to clear up the information for other readers. You do aclnowledge that whether the input voltage is 20v or 60v makes no difference on the driving current which is possible? If a vesc is rated to 80 amps it doesnt matter what input voltage within its usable range you test at. It is my understanding that rating remains pretty much constant. If anything I believe lower input voltage probably reduces the current rating. More fet on-time when driving the motor to achieve given amps.
Except for their dual DRV handled by a single MCU design soon to be released found in the post here:
It will be hard to get the improved source codes unless Enertion makes a github page detailing the changes and posting it. From past post it will be unlikely unless they no longer have a need to profit off of it will it become open source.
Maybe I’m not communicating effectively, Sorry! Long story short, I am the firmware developer working with Enertion on the FOCBOX Unity and I want to reassure everyone the code will be open sourced in a git repository when its ready for release. Check the new activity in the thread you linked, and if you have any more questions regarding the Unity ask them there and I will see if I can provide answers.
Well personally I’m skeptical because of all the access points it has from the xt90, the on /off button, the cables, and the at the center of the top it’s got that removable bit for accessing the plug-ins… So I wouldn’t call it waterproof, but it seems at least pretty water resistant as long as all these are sealed and closed.
EDIT:
I added some more photos to my post above as they added some to their site.
Lol so if you want to utilize the canbus and connect two of these, say goodbye to waterproof as you’ll have to remove the top center cover for both! Now that’s a gapping hole! Also right next to that is what appears to be several exhaust vents…
Haha Omg I didn’t even consider that. I guess they figure you’d just flip one over, but then that makes running cables between the two a pain, lol. Not very well thought out… A dual case should be developed so they don’t require two on switches…
Listed dimensions are 100×92.5x22 mm I think. For a dual motor drive thats a lot of real estate eaten up. For reference a focbox is somewhere around 60×65×25 mm (estimate). The unity dual motor driver we are making is roughly 110x70x20 mm and saves you some extra wiring space. Not sure of original vesc 6 dimensions?
