I have been testing out different charger revisions on my bike, looking for one that will both charge my pack without the temp sensor boards connect and communicate with the motor controller.
revision 2017 won't charge, but will count down the bars
I have 3 versions of 3001:
the 79kb one will charge to 155v as in the "old" way (so tr = 1.5A).
doesnt count down the bars
the 83kb one does the same as above
the 85kb one behaves like 2017.
im getting hold of more revisions.
If you have any copy of a charger firmware (.hex file), PM me.
