The Tenpower 50XG has finally arrived at about energy testing, this one has been hotly anticipated across the high-performance community. It brings a tabless cylindrical design to the 21700 format with the following reported stats:
🔋 Tenpower 50XG (21700)
Gravimetric energy density: 257 Wh kg⁻¹
Volumetric energy density: 707 Wh L⁻¹
Power density: 2,314 W kg⁻¹
Nominal rating: 5 Ah at 3.6 V
Energy: 18 Wh
Max continuous discharge: 45 A
The appeal here is straightforward. Tabless construction reduces internal resistance and improves heat generation. It is the type of architecture that has reshaped expectations at pack level, particularly for applications needing fast charge and high power.
This cell has been circulating in conversations for months as one of the more interesting new releases in the high performance cylindrical space. Getting it into our workflow now lets us validate whether the real behaviour matches the buzz and where it fits compared with established players in this category including the EVE50PL, Reliance RS50, and Molicel P50B.
