High Discharge Capability
The M65A can provide continuous 26 A current, allowing it to deliver steady power over extended periods. Its low internal resistance reduces voltage drop and heat, while its high energy density ensures long runtime. This makes it suitable for applications that need both energy and power such as e-bikes, e-scooters, drones, and robot cleaners.
Key points:
- Sustained power, not just short bursts.
- Efficient and safe due to low heat generation.
- Balanced performance for energy-demanding and power-demanding devices.
- Wide operating temperature range (–30 °C to +60 °C).
Continuous currents up to 26 A or repeated high-current bursts may increase heat and trigger safety cutoffs. Proper thermal management and a BMS are essential.
