Tenpower 21700 Batteries

Tenpower 21700 batteries are tabless, high-drain lithium-ion cells built for serious current delivery in demanding pack builds.

Tenpower is a cylindrical cell manufacturer focused on high-output cells, with a 21700 line — represented by cells like the 50XG (5000mAh, 90A-class) — that pairs strong continuous current with real capacity. The tabless construction is the reason: instead of routing current through a single welded tab, tabless cells connect along the full electrode edge, lowering internal resistance for flatter voltage under load, cooler operation, and stronger sustained output.

That blend of high capacity and high current makes Tenpower a capable choice for drones, e-mobility, and other builds where both runtime and power are on the line.
