Ok a quick update.
I have 17 pcs tested working. 2 more waiting for replacement parts.
Although I have the giant load tester ready, I realise I don’t have good enough of a battery source to test it at 80A. I have a couple layers of pure nickel strips on my 12s4p pack, but I fear it may still be not enough for a “semi” continuous 80A test. Not wanting to make you guys wait any longer; I will leave it to my batch 2 to have my fun with it(will take video).
So my estimated ship day is early next week, when I have the final ones fixed. Sorry it took a while, but there are a lot of testing to be done without automatic tools to tests. Each pcs was tested manually.
Testing sequence
12S, ESC loaded
Power up
plug BMS USB
read State (Should be load enabled)
Test pack charge (55V, 2.4A)
read operating state (should read charging)
Test ESC loading (run motor)
Test Canbus access to DBMS
*Note I am unable to fully test the balancing capability of each board, please test charging your pack initially with caution.
(my display is water damaged, I removed it, that’s why you can look trough the window and see the LED’s on the BMS)
I can now enable my board by using the power button OR by kicking against the wheel OR by just placing it on the ground and start pushing the board once (like those kids or sporty people do) xD.
And exactly what you described; I already had the VESC CAN bus and +5V + GND connected to the BMS for firmware updates and acces to the BMS trough the Metr bluetooth module and the VESC, I only connected the CAN_ENABLE to the +5V and made a small firmware update (to go to normal mode instead of external mode when an external power on signal is applied) and the video shows the result!
This day ( 1-7-'18 EU date method ) will be the day the power button died and will no longer be implemented in my new builds.
So I’m set to receive one of the new DieBieBMS and wanted to know, for that push to start, what would I need to upload and do to the hardware of my BMS to implement that?
@JTAG Just looked up the board dimensions in this thread, is 140x60mm still accurate? I measured my custom pla-printed battery/electronics enclosure and it should fit (barely )
