18650 Li-ion Battery
18650 power tool battery 11.1V 18Ah
Dimension: 57*170*70mm · Model: ICR18650 3S9P
View data sheetPower Tools
Lithium-ion batteries are extensively used by the power tool industry as they are light weight and carry higher battery energy. They provide durable running time for tools and machines.
Industry Pain Points
What Goes Wrong Today
- A pack that is light enough but cannot hold the current the motor draws under load
- Tool housings with no room to grow in any direction
- Service packs that no longer match the original terminal or latch
- Cells that sag on a cold morning start
Customer Needs
What Buyers Ask For
- A published continuous and maximum discharge current, not just a capacity
- A 3S or 4S arrangement sized to the tool's motor voltage
- A pack drawn to the housing, with the exact terminal in place
- Consistent cells so a fleet of tools behaves the same way

How A Project Runs
The same route for every industry, from the first drawing to the packed carton.
Requirement Analysis
Voltage, run time, peak current, ambient range, enclosure and connector. If the run time is still open we work back from the load and the hours you need.
Chemistry And Cell Selection
LiFePO4 where cycle life leads, lithium ion where energy density leads, lithium polymer where the space is a thin rectangle, Ni-MH where the product is locked to a 1.2V cell size.
Series And Parallel Design
The arrangement sets voltage and capacity. We publish it for every standard pack, for example IFR32700 4S17P for 12V 100Ah, so the comparison is transparent.
Protection And Balancing
Over-charge, over-discharge, over-current and over-temperature protection with internal cell balancing. Communication ports where the system needs them.
Sample And Test
After price confirmation you can request samples to test. Cells and packs are checked against the parameter table published for that model.
Case Wiring And Label
ABS or lead acid style case, aluminium case for e-bike packs, PVC wrap for modules, with your terminal, cable length, connector and logo.
Questions About Power Tools Batteries
How much current can an 18650 tool pack deliver?
The 11.1V 18Ah 3S9P pack is published at 18A maximum continuous discharge, which is 1.0C. Higher rates are a matter of adding parallel strings.
Why 11.1V and not 12V?
Three ICR18650 cells in series give 11.1V nominal and 12.6V fully charged. Tools sold as 12V usually run on this 3S arrangement.
Can you match our existing pack?
Send the pack, or its dimension, voltage, capacity and terminal, and we will quote a like for like build.
