The THOR-18650 is a 3.7V 3000mAh 18650 cylindrical lithium-ion cell, 18.0 × 65.0 mm (Ø × H). The 18650 format is the industry standard for building series and parallel battery packs, and is widely used in power tools, e-bikes, portable power stations, LED lighting, medical carts, and industrial instruments.

THOR Power builds the THOR-18650 into custom series/parallel packs — matched cells, BMS protection, nickel busbars, housing and the connector of your choice. Bare cells and welded modules are also available. Tell us your target voltage, runtime and discharge current, and our engineers will size the pack for you.

• Proven 3.7 V nominal cylindrical cells from tier-1 suppliers
• Long cycle life — typically several hundred to 1,000+ cycles
• Built-in protection: overcharge, over-discharge, short-circuit
• Custom series/parallel configuration, connector & BMS
• UN38.3 / MSDS ready; CE, KC, ROHS on request
