Not sure why we haven’t seen more locking connectors in esk8 electrical components. Sometimes it really feels as if those designing them have never actually looked at JST’s catalog or something…
This design is wonderfully thin without the heatsink.
Suggestion: use a smaller copper heatsink with bigger mass but much thinner profile.
If you can get it down to 10-13mm, one could stack two of these and they would be similar height to the batteries → ideal for a cramming a 4WD in a board with integrated enclosure.
I like that. In that case, I would recommend removing the connector on the other side making sure it’s flat. Like that it can be directly glued onto a heatsink (such as on some enclosures)
Awesome formfactor, good job!
Design looks thought through. How is it managin without any electrolytics tho, how much cap could you fit in just the ceramics?
Good that you did a contineuos 1kw test. But…you did test 13S that you claim? Or are you just refering to maxvalues and thinking its cool?
Did someone make an official esk8.news torquebench yet where we send samples to get them tested?.. Feels overdue
