What to check before you buy
- Cell model
- Ask which cell the pack uses; capacity and discharge depend mainly on the cell.
- Discharge current
- Li-ion cells deliver less current than LiPo; check the continuous rating against your motors.
- Configuration
- Check series and parallel count (such as 6S2P), which set voltage and capacity.
- Weight and energy
- Compare watt-hours per kilogram across packs of the same voltage.
- Connector and BMS
- Check the discharge connector and whether a pack has a balance lead or a protection board.
- Shipping
- Lithium-ion packs ship as dangerous goods; ask for the test report and safety data sheet your carrier needs.
Li-ion batteries FAQ
Li-ion or LiPo for drones?
Li-ion stores more energy per gram and suits long cruise; LiPo delivers more current for punch and racing.
What is the difference between 18650 and 21700?
The numbers are size: 18 mm by 65 mm and 21 mm by 70 mm. 21700 cells usually hold more capacity.
Can I charge Li-ion with a LiPo charger?
Many chargers have a Li-ion mode; use the charge voltage the cell maker specifies.
