Many more builders are using huge packs today, two years ago stuffing 60+ cells in a board would likely get you blasted on the forums for not needing the range and having a heavy board but people are beginning to see the benefits and going big.
Maintaining a large pack is a little different than 100 to 200 watt-hour pack. Most BMS circuits only output around .09 amps when balance charging which may work fine for a XXs1p battery but it takes many times longer to balance a larger battery with big P groups. Overtime insufficient balance charging will lead to a large enough drop in voltage to significantly reduce your range due to the low cell voltage cut-off found in a good BMS.
In this scenario, if the board has a bypassed BMS, you are running the risk of dropping the cell voltage below recommended levels and damaging the cells or worse. I have noticed many builders now using this method and relying on the VESC software to do all low voltage monitoring without any fail safe or accounting for individual cells. This may seem like a sparkling idea on a fresh board and battery but life is never perfect, cells will drift and if you are not monitoring your cells you need to be using a BMS and leaving it on the charger longer once it reaches its target voltage.
It can take weeks for a BMS to balance a large pack if it has drifted significantly. .09 amps is a snails pace when charging a 500+ watt-hour pack. Keep this in mind next time you hear the fan in your power supply turn off, that is usually the moment the charger has reached the target voltage and float charging commences.
