Preparing new things/tests for battery
18x21700 cells somewhat fit in this configuration, it is a bit tall.
9S2P would work based on my previous use on 7S4P.
Not fan of such configs to do the welds!!
Liking the frost/transparent look.
Batt Box prints with zero support.
The new 21700 BAK tabless cells as tested by @lishine are very interesting to me for tests and general education about new cell developpements. (especially VS MOLICELL).
VESC heats more than ESC?
up to 190A phase (peak, reported by vesc)
That is in no HW limits mode, and with special high current mode enabled to measure only on two phases at once.
150A peak is safe, if the motor parameters are well detected and configured.
Battery max continuous we tested was around 50A. Continuous is 30 min +, peak is 30S+ as per automotive standards.
Our commercial product motor runs 110A phase on those 84100 under 14S (checked the actual settings, 120A phase and 100A battery is our validated delivered setting. > 17.5N.m at the shaft)
Here are some projects we are working on on proto phase :
one with X2 MIC-2000 (84100HP) and 2x 14S4P EVE 50E, up to 350 kgs 45kph (3 vehicules)
one with 2x bigger motor and silixcon controllers ( 
but 
), 2x 14S10P P42A, 250kgs, up to 90kph. (5 vehicules)
Other projects I can not talk about 
Wheels on the ground is generally harder to control than prop driven applications, where a good prop selection can prevent from the need of phase current sensing and limitation.
MIC-2000 Motor with 84100HP controller built in :
Those are for LMX Bikes…
Yes, for light mobility vehicles. The stator and rotor is the same as lmx56, but based on open source controller, and max cost effectiveness.
I am the founder of LMX.
We are a team of 15 at the moment 
M365 update process. Had to solder flash wires to the PCB (easy to do)
St link driver can not install on ARM64 (surface laptop 7 with snapdragon)
Hope that I will be able to run sensorless in bldc mode.
Hit a dead end it seems with m365 reflash.
Flashing was successful but the esc can not be detected by vesc.
The newer vesc tool give a firmware too old error, and the older 2.0 or 3.0 give read error…
It seems like my under baord assist controller has failed.
When I use some throttle, the motor does not start well. When connecting the app, I see that the mosfet temp reading goes high whenever the throttle is applied.
Ambient temp was 11°C and the value would drop to that when throttle was released.
I tried to set mos temp limit to 190°C (max of vesc tool) but it seems the read value is out of bounds.
I am pretty sure it is water/saltwater creeping under the epoxy and contacting on the temp sensing component, they are located close to the phase output voltage measurements.
All 6 MOSfets test OK, and I tested with two different motors to make sure it is not something else.
I removed the epoxy and could see some humidity below.
Now sanded down all epoxy and drying the system, to see if the issue can go away before I re-epoxy cleanly the parts.
The temp sensor issue of the vesc seems to have cured itself after drying on a heater at 35° for a few days.
Will have to do a coat of thickened resin to seal it up again
