Frequently Asked Questions

What is the expected cycle life?

  • According to third-party sources (Tenergy), the cell can support ~500 cycles.
  • In practice, for B2B designs, you should balance cycle profile with discharge current to maximize longevity.

What protection / BMS design is recommended?

  • Use a BMS with over-current protection — since the cell supports 10 A discharge.
  • Include voltage cutoffs: set over-voltage at 4.2 V and under-voltage at ~2.5 V to protect cell life.
  • Because of the wide temperature range (–40 °C to 60 °C), thermal-management or temperature sensing is advisable in the pack.

What competitor cells might be comparable?

  • The M35A competes in the “high-capacity, moderate-discharge” space — similar to Samsung 35E but with a higher discharge current.
  • Depending on the application priority (power vs. capacity), consider cells like Molicel P30B / P28A for higher current, or high-capacity cells for lower-current use-cases.

What packaging / mechanical design considerations should be made?

  • Given its 18650 form factor and standard dimensions, it’s compatible with common 18650 cell holders/modules.
  • Ensure cell matching (voltage / IR) during pack assembly to prevent imbalance, especially in mult-cell packs.
