After the two test prototypes, the second generation of LEIYU went on sale. The motor is now a high power-density brushless motor: pure copper windings, N45SH high-temperature magnets and FOC vector control. The gears are made from 20CrMnTi alloy steel, carburised and hardened, and run in a gearbox with an aluminium-alloy housing; the tool housing is split, so a repair replaces only the damaged part. The bearings and cells were renewed as well. Motor ratings are never overstated: what the rating plate says is what you get.
The body changed too. The first generation was blue with red accents; the second generation is the green and yellow you see now. The battery platform stayed the same, still 21 V, with one more capacity, 8.0 Ah, so there are now four: 2.0, 4.0, 6.0 and 8.0 Ah.
