Ytst-c01 Battery

The YTST-C01 relies on a built-in Protection Circuit Module (PCM) to prevent overcharge and over-discharge. However, you must still follow best practices:

DON'T:

3.1 Initial capacity
At 0.2 C, average capacity = 2153 mAh (102.5% of nominal). At 1 C, capacity = 2058 mAh (98.0%). At 3 C, capacity reduced to 1724 mAh (82.1%) due to ohmic polarization.

3.2 Cycle life
After 500 cycles: 82.3% remaining capacity. Linear extrapolation suggests end-of-life (80% SOH) at ~580 cycles. DC internal resistance increased from 38 mΩ to 43.5 mΩ. ytst-c01 battery

3.3 Thermal behavior
Maximum surface temperature during 2 C discharge: 42.8 °C (ambient 25 °C). At 3 C, peak reached 51.2 °C, exceeding vendor’s “safe” 50 °C limit.

3.4 Impedance spectroscopy
Charge-transfer resistance rose from 22 mΩ to 31 mΩ after 500 cycles, suggesting electrode-electrolyte interface degradation. The YTST-C01 relies on a built-in Protection Circuit

Lithium-ion batteries dominate the rechargeable market, but new form factors (e.g., YTST-C01) often lack third-party validation. The YTST-C01—designated as a cylindrical 14650-type cell—claims a nominal voltage of 3.7 V, energy density of 170 Wh/kg, and support for 3 C continuous discharge. This study independently tests those specifications to inform engineers and researchers. DON'T: 3
