How the 52 Cells Are Wired
Picture four cells lying side by side and sharing the load; together they offer 20 Ah. Thirteen of these quartets are then chained one after another, multiplying the voltage by thirteen. A fully filled cell sits at 4.2 V, so the chain peaks at 54.6 V. The 35.1 V floor works out to 2.7 V per quartet.
Because the management electronics split charging and discharging onto separate sockets, the charger and the motor driver never share a socket. Socket kinds and conductor pinout are printed on the interface diagram that accompanies the datasheet.
What a 30 A Maximum Means on the Road
The BMS passes up to 30 A. At 48 V, the very top of that range is close to 1.4 kW, which points toward lightweight two-wheelers rather than powerful long-haul bikes. The regular discharging figure in the data is 10 A.
Distance per charge hinges on motor consumption, rider weight, terrain and speed. The battery data states energy, not a range figure.
Where It Works
Likely roles: a swap-in battery for a 48 V light electric motorbike, daily travel, parcel couriers and hire programmes. Your riding pattern and distance expectations settle the final answer.
Approvals and Paperwork
Required approvals and freight paperwork differ by target country and by final version.
