Graded cells, a full-protection BMS, welded busbars and a sealed case — the parts you never see are the ones that decide how long the pack lasts.
No pack skips a stage — the scooter battery and the rack module go down the same line.
01Every cell batch is inspected the moment it arrives.
02Cells graded and matched by capacity and resistance, so no weak cell drags the pack down.
03Matched cells welded to a set standard and wired to a full-protection BMS.
04Every finished pack is charge–discharge cycled and balance-checked.
05Serial-tagged for traceability, then packed and shipped.
