yes the Aipas M1 has 48V 17.5Ah Battery Capacity listed.

- 100% Charge (54.6V–58.4V): The battery is fully saturated. Charging beyond this risks overheating due to overvoltage.
- 50% Charge (~51V–52V): The “knee” of the discharge curve where voltage begins declining more noticeably.
- 20% Charge (~48V–49V): Critical threshold—discharging below this regularly degrades cell lifespan.

might want to double check those numbers My understanding is 53.3-54 is full 47.4 is half and I try not to go below 43= 25%

54.6 full SOC for 48v.
Like i've said before, there is a difference between fully saturated and resting SOC.
Numbers are good

What i am trying to get across is that 54.2v is not a fully charged/balanced 48v ebike battery.
Plus these things are pretty wonky so things could be a bit weak in the charger or elsewhere along the line somewhere...

Perhaps to prevent overcharging, anyway I checked the resting voltage this morning still 54.2 v.

Second day voltage check now 54.3 v

Looking at the 52-volt chart, it says it is for 18650 cells. I just bought a 52-volt battery with 21700 cells. How does the chart change for those cells?

The chemistry matters more than the size of the cell.
