Collection: Li-ion Cells

Genuine EVE and HAKADI cylindrical Li-ion cells in 18650 and 21700 format: from 1500mAh to 5000mAh, with maximum discharge currents from 15A up to 125A on the EVE-50PL, all lithium-ion chemistry.

With cylindrical cells the trade-off is always capacity against power: a 21700 of 5000mAh at 15A is an energy cell, right for packs that have to run a long time; the same capacity at 125A is a power cell, for tools, drones and e-bikes. Pick the wrong one and you get overheating or half the run time.

Every cell is genuine and traceable. Join them by spot welding, never by soldering straight onto the terminals, and the pack always needs a BMS.
