Clear specifications. Fewer surprises.
Is a 2000 mAh cell the same as a 2000 mAh pack?
Not necessarily. Series connections increase voltage; parallel connections increase capacity. A 5S2P pack made with 2000 mAh cells has a calculated 4000 mAh capacity. Cell count and the series/parallel arrangement must be stated together. Delivered capacity is defined by the accepted pack specification.
Can every 18V–21V tool use the same pack?
No. Voltage labels alone do not establish compatibility. Check the slide geometry, contacts, polarity, electronics, current demand and charger for the exact model.
Does more Ah mean more torque?
Ah describes capacity, not a guaranteed increase in motor output or torque. Power delivery also depends on the cells, protection board, temperature, connectors and the tool.
Are the pictures production-label approvals?
The custom pack images are GEAKITA branding visualisations based on supplied product references. Housing variants, ports, displays, capacity labels and packing artwork are approved for the selected configuration before production.
