Electric Unicycle King Song S22 Pro 1776Wh Battery 4000W Motor Suspension

The graphic above illustrates a core differentiation of a similar ‘high capacity’ Samsung 50E cell, to a 40T, in maintaining a higher voltage under a constant 15 Amp load—the effects of pulsed-power output in an Electric Unicycle application are even greater in the ‘burst’ capability of a cell with a significantly lower internal resistance.   

Beyond the advantage of providing more power-on-demand throughout the discharge curve, there are a number of other inherent advantages of the Samsung 40T cell, that include:

– Considerably Safer: in stress/abuse tests, the 40T battery cells can operate at a much greater range of parameters, without premature degradation of cell’s internal structure.– Designed for Fast-charging: the 40T cell is rated for a charge rate of 6A vs 1.5-3.5A with the LG M50LT & is subject to a narrow band of temperature operation to achieve the higher rate of charge.
– Temperature Variance Range: another advantage of the 40T is that it can operated in ambientant extreme temperatures , from -4°F up to 176°F, while the M50LT cell is limited to a much more prescribed temperature range.
– Higher Operating Efficiency: with an internal resistance of 12.6mOhm vs 18.3mOhm of the M50LT, the 40T operates more efficently in higher discharge scenarios, such as high-speed runs, or sustained hill-climbing, meaning that a greater proportion of the cell’s energy is able to do useful work, rather than being converted into parastic heat. The Wh rating of a cell is not the complete picture!
– Longevity & Stability: based on available data, in like-for-like high demand applications, a high-power 40T cell will offer superior % capacity over a couple hundred cycles, than a ‘high capacity’ cell & more importantly, the risks of latent degradation, leading to thermal run-away is reduced.
