Capacity is a configuration
The same tool model may be supplied with different supported battery capacities and quantities. Keep the tool model, cell capacity, pack capacity and charger as separate fields in the order.
GEAKITA / POWER SYSTEMSPower the tool.
Power the tool.
Extend the possibilities.
Standard capacity choices, a 4.0Ah high-function pack and the HANDY 20-cell platform. Select by runtime needs, electrical fit and the complete charging setup.
Five cell-capacity choices.
A configuration for the job.
1300mAh cell option
1500mAh cell option
1800mAh cell option
2000mAh cell option
2500mAh cell option
Choose the supported cell capacity for the selected standard pack: 1300 / 1500 / 1800 / 2000 / 2500 mAh. Record complete-pack capacity separately. Pack construction, tool compatibility and the accepted specification determine the delivered configuration.
| 4-cell family | 16.8V tool family; select the exact DK tool and interface |
|---|---|
| 5-cell family | 21V tool family; compact pack configuration |
| 8-cell family | 16.8V tool family; compare the larger housing and exact interface |
| 10-cell family | 21V tool family; specify series/parallel arrangement and housing |
| 15-cell family | 21V tool family; balance capacity, weight and tool clearance |
Specify the complete system
Match the cell discharge capability and protection board to the tool load. Check the rail interface, battery envelope and charger protocol before selecting a larger pack.
One cell number.
Different complete-pack capacities.
Keep three decisions separate.
- Tool fit: select the voltage family and exact mechanical/electrical interface.
- Cell choice: choose 1300, 1500, 1800, 2000 or 2500 mAh with the required discharge capability.
- Pack build: specify the series/parallel arrangement and resulting complete-pack capacity.
For the same arrangement and comparable cells, more capacity means more stored charge. Actual runtime also depends on the tool, load, temperature and discharge characteristics.

Illustrative arithmetic for 1P, 2P and 3P builds; these are not a claim that every housing supports every build.
| Individual cell | 1P pack | 2P pack | 3P pack |
|---|---|---|---|
| 1300 mAh | 1.3 Ah | 2.6 Ah | 3.9 Ah |
| 1500 mAh | 1.5 Ah | 3 Ah | 4.5 Ah |
| 1800 mAh | 1.8 Ah | 3.6 Ah | 5.4 Ah |
| 2000 mAh | 2 Ah | 4 Ah | 6 Ah |
| 2500 mAh | 2.5 Ah | 5 Ah | 7.5 Ah |
Parallel groups add capacity. Series groups establish pack voltage. Delivered ratings follow the agreed cell and pack specifications.

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.
