Planning on buying one D140 12s BMS from esk8Life.com
Could you just explain a bit more precisely were the ESC positive and negative wires would go? And what sort of balance connectors should be used from the battery to the BMS?

this is a pretty good diagram of bypassed bms.
also, the bms comes with balance leads.

looks ok, just take your time when wiring up the balance leads. i haven’t worked with lipos before.
balance lead 1 should be pack voltage, the drop down in voltage each subsequent series.
only thing i can see, as it’s diagrammed, your voltmeter will always be on. be sure to move the voltage neg wire after the loop key.

I made a new, simpler one. In this curcuit the voltmeter will only be on when the xt90 anti-spark is plugged in. The female/male parts are 5.5mm bullets.

After some reading I understood that on some BMS´s the black balance wire from battery 4 (which is not used in the diagram above) should be connected to the B- port. Does this have to be done on the Bestech 140D 12s BMS?
no, not that I’m aware of, bms diagram doesn’t indicate that.
I would just attach the charge wires directly to your main power leads, save some connectors. but wiring looks accurate.

I need to order some bms for some random projects so can fit in additional bms’ in this order.
I’d like to limit the models to the D140, you can see the specs here:

if you’ve had a burning need for a different module, please let me know, i can ask. but getting a spec and quote for each different module adds to lead time.
bestech is back in business on feb 25.

I definitely need at least 1 more 10s and a couple 12s’s. Maybe more if I mess up the one I already have. Lol. BTW, did you get the nickel out? I never saw a tracking number. Just itching to fire up my spot welder! Thanks for helping out the community!
I’ll take 2 each
this shipping service i’m using is supposed to send out tracking details as they’re created but it’s been spotty, not sure why.
it was dropped in the mail two days ago but it’s still not showing status: 9400110298370379790337
i’m sure you’ll get it in a couple days.
