I bought the HCX-D596LI12S80A Litech BMS here and installed with my 2 6s battery in series according to this
It comes with two wiring leads for e-switch installation, which I put in connection with an alligator just for testing time.
Saying that by-passing the BMS (ESC to batteries) everything works just fine, I can’t get to have the ESC turned on with the BMS.
as you can see battery pack is (almost fully) charged
and I got the same voltage measure between the yellow circles, between which I was not expecting. At least not with inverted polarity… But it’s my first project, so I can definetively be wrong
Finally I got this weird voltage reading on the load (ESC port), no matter if I turn the E-switch on or off (connecting or disconnecting the saidwiring leads )
any guess ?
Are you discharging from the p- or b-?
Battery negative is on B-
Ok but do you plan on using the bms for discharge?
This may help a bit its not the same but informative
Wiring and switch
no, I would like to bypass it for discharge
Hmm let me look into the bms one sec. Ok looks like you would have to discharge from the bms for this switch to work as it would not be do anything other wise.
Charging voltage 50.4V
Maximal continuous charging current 20A
Maximal continuous discharging current 80A
Current consumption ≤50uA
also, I saw your diagram, I actually aimed for the same configuration. I should got it right
discharging bypass would it be just to be sure, but I guess I can limit the ESC to 80A.
Charging is not a problem.
Now, is the wiring ok? how do I need to change it?
I actually can’t see the picture
Try cycling the bms a few times.
