The bms only appears to turn on when you plug in the charger because the charger supplies power to the output side of the bms.
This is why your Vesc turns on and your meter lights up.
You still need to manually turn the bms on to charge or it will not work correctly.
Definitely gonna check that out!
I thought I shorted some things which caused it to not charge over 69%…
Fingers crossed what you describe is the culprit!
@Namasaki I think I will copy your battary/bms system for my first build. Will this BMS work with an 8s pack too?
I would love to start with 8s and upgrade to 10s later on (need to cut cost).
Thanks for all your work in this forum, your replies have helped me out a lot already!
Would love your opinion or maybe you can shine some light on why this BMS isn’t as expensive as the D223V1.
That 10amp discharge difference does not bother me
Exactly!
I was a little stunned because of the price difference and the little specs difference there is.
Only main differences are:
-size
-max discharge
All others are adjustable.
Only reason for this price difference I could think of is the manufacturing since it is not a “sandwich bms” and the slightly lower discharge level
Oh forgot to mention: later I discovered one of my 2s packs had started to swell slightly (the one closest to my BMS) so I think that is where the heat came from. Not sure though.
Will look into the packs this weekend
Hey man, thanks heaps for this post. I just finished my first build following your build. I hope to find someone with a computer so I can set it up. Thanks again for such a detailed build log and answering everyone’s questions. Cheers
