    12s8p advice

    Hi, i'm designing and building an 12s8p battery pack for an e-bike conversion, using 18650 cells.

    I'm planning to use a Daly 12S BMS for charging only, with bypass discharging (mainly since I can't seem to find a cheap-ish one), initially with no discharge protection but will add this later through the attached arduino.

    I have some questions regarding the wiring, and I want to make sure the configuration (meaning nickel strips and so on) is correct.

    Bus bars will be used for power output.

    See below attachments for top (diagram) and the bottom.

    Does this seem correct? Any changes I should consider?

    Just curious, but why 12s (vs 13s or 14s)? That's an odd voltage for a battery

      The ESC i'll use recommends a 3-12s li-ion, and I saw quite a few designs in similar configurations.
