As of this writing I have been testing the Neobox V4 in a dual driver configuration powering two maytech 6374 190kv sensored motors set to a max motor amp draw of 60a running off a custom 50v - 17ah Sanyo 12s4p pack. Under normal commuting speeds (15-20mph avg) I have experienced zero faults or systemic hardware failure to date, with a minimum riding threshold of 7mph and a maximum sustained speed of 40mph. During the extended long range test the EBmaker anti-park switch I was using failed closed under sustained load, but likely unrelated to any ESC related hardware functions.
That being Said I have had less than ten hours in total of road testing. So I will summarize my key test points below.
FIRMWARE: v3.62
FOC DETECTION PASS/FAIL: PASS
FOC SPIN UP PASS FAIL: PENDING
BLDC MOTOR DETECTION PASS/FAIL: PASS
BLDC MOTOR SPIN UP: PASS
SYS TEST SUSTAIN ON PASS/FAIL: PASS
SYS HARDWARE READ WRITE PASS/FAIL: PASS
Closing Notes:
While I found no consistent issues with hardware operations, I did struggle to accommodate the internal wire routing design and while it is visually pleasing, I still find the original top slot design a more adaptable and efficient design vs the enclosed routing and feel this should be addressed in further revisions to the production hardware, especially in relation to the placement and accessibility of the PPM stand off pins.
In summary apart from a few small physical qualms with the design I find the Neobox v4 to be consistently reliable and mostly straightforward to install and configure using the stock settings.
