I am a ebike "newbie" and have some very basic suppositions but no definitive ideas. One of these is the oft reference, in BMS installs, to a "first battery group." Depending on the BMS, extra wire is attached to "negative of first battery group." Fairly simple...' From that and more, seems first or last group is arbitrary. Which means to me that the sequencing of the wires like the groupings, is as arbitrary.
Is that right? If so, then how does one interpret the information on a BMS diagram...say B10...B1, aside from fact the "balance" wires must be ordered 1,2, 3, 4...etc?
Seems to me might be good to be consistent to do each pack same way...so wires to motor extend from opposite poles of last group. or negative of first group and positive of last group...still not sure of that either.
So, being consistent here is mandatory.
