More cycles, more energy, more freedom.

Traditional lithium lets you use only part of the capacity and usually recharge once a day. With Super Barrel Graphene, you can discharge 100% and recharge up to 5 times per day with no performance loss.

Lithium
7.2 kWh × 1 cycle = 7.2 kWh/day
Graphene
8 kWh × 5 cycles = 40 kWh/day
Result: up to +470% more available energy every day, with zero degradation.
