Yeah, from that document I did the figure 3 balanced charging as opposed to the figure 3 "perfectly" balanced charging. While conceptually I get that the "perfectly" is a little better, it is also more complicated to set up since you have to work out the resistances of the cable runs and any connections. In this case just balanced charging is good enough. Another thing to keep in mind is that it's a bigger issue with "dumb" lead-acid batteries. Each of the new LiFePO4 batteries has their own smart BMS to help manage balances, plus parallel in general helps balance out batteries vs the serial setup Hisun used with the awful Discover 6V batteries. I did use equal length brand new 1/0 AWG cables for my connections except for re-using the two final cables that connected to the motor controller.
