The same cell, five very different duties
An 18650 in a medical cart and an 18650 in an impact driver are not the same product. What changes is the grade — capacity-first or current-first — and the protection strategy wrapped around it.
Power tools & garden equipment
Repeated peak draws and fast charge turnaround in a housing with little cooling.
- Design point: 20–45 A per cell
- Charge acceptance often binds before discharge does
E-mobility
E-bike, scooter and light traction packs bought on range and warranty.
- Design point: 10–25 A per cell
- Cycle life at real depth of discharge drives cost per kilometre
Energy storage
Residential, commercial and UPS storage running at fractions of a C.
- Design point: 0.2 C–0.5 C
- Capacity per cell and calendar life outweigh peak current
Drones & eVTOL
Where energy density and burst discharge bind at the same time.
- Design point: 45–60 A per cell
- Impedance and heating rate decide usable capacity
Medical & instrumentation
Modest current, but the heaviest documentation burden of any application.
- Design point: under 10 A per cell
- Batch-level traceability and per-batch certification
Battery packs & BMS
Assembled packs, protection boards and interconnect parts built around the cell you chose.
- Welded interconnects, not soldered
- BMS configured to the cell's real voltage and temperature window

Before you specify
Three questions that settle most cell choices
What is the peak, and for how long?
Peak current and its duration decide the discharge grade. A two-second pulse and a two-minute pull are different design problems.
How fast must it charge?
If the pack has to be ready in an hour, maximum charge current matters more than the discharge rating.
What can the housing dissipate?
Every current rating carries a temperature cut-off. No thermal path means derating, whatever the data sheet headline says.
Describe the duty, not the part number
Load profile, envelope and target cycle life. We will come back with candidate cells and the documentation behind each one.
