The most valuable component of any Wheel is its battery pack, the beating pulse of the machine. Over the years it has been found, from painful experience, that pairing a high-powered machine with a battery cell that is not designed for high peak-power applications can result in latent/delayed catastrophic thermal runaway events. To try to minimize this risk, we at eWheels, have insisted the use of high-powered battery cells, particularly on smaller 4 parallel packs, such as the MTen4, A2, T4, S18, Hero, S22, & Master—as the number of parallels increase, the load on each cells decreases accordingly. Until recently, there was the trade-off between power & capacity; now, with the advent of the new Samsung 50S cell, one can have both!

• Energy Density: 50S has a 20% increase in energy density over the 40T, providing a corresponding increase in range without any weight/bulk penalty.
• Higher Operating Temperatures: the specifications of the 50S has a vast operating range, from -20 to 80°C/-4 to 176°F vs -20-60°C/-4-140°F with the commonly used 50E/GB cell & as high as 100°C/212°F in Samsung’s test data! This massive margin not only allows the 50S to output up to 3x more power than the 50E, but perhaps more importantly, will greatly improve battery pack safety, there is no conceivable scenario in which these limits will ever be reached, or exceeded.  
• Power Output: the maximum sustained power output on the 50s is 45A vs 15A on the 50E. At pack level, this represents a total potential sustained output of 15,120W, on the S16. From a Rider’s perspective, the main benefit of having this power on-tap is once the pack(s) have been partially depleted, reducing the risk of cut-outs when power is required.
