Design a custom pack with this cell:

Application suitability

PowerwallsUsable for powerwalls but lower capacity means you'll need more cells to hit your target kWh.
Ebike PacksNot enough discharge for ebike use. Voltage sag would be a problem under load.
Car AudioNot enough discharge for car audio amplifiers. You need at least 15-20A continuous for most setups.
High-Drain VapingBelow the 25A Mooch CDR threshold that high-drain vaping needs. Use a higher-drain cell.
FlashlightsLower capacity means shorter runtime. Better cells are available for flashlight use.
Power ToolsNot enough discharge or capacity for power tool use.

Frequently asked questions

Handling and safety

Lithium cells can be dangerous if mishandled. A few things to keep in mind:

  • Never charge above 4.2V or discharge below 3V.
  • Store cells at around 3.6-3.8V (roughly 40-60% charge) for long-term storage.
  • Don't mix cells with different capacities, chemistries, or states of charge in a pack.
  • Inspect wraps before use. A torn wrap can cause a short circuit.
  • Always use a BMS or balance charger appropriate for your pack configuration.
  • Keep cells away from metal objects, keys, and coins. A short across the terminals can cause fire.
