Silver fish ebike battery pack 48v 20ahBattery processing
Feature:High energy density, no memory effect, superior safety, flat discharge voltage, long life cycle of 500 times
Applications:Lapt computers,Portable devices,Flashlights, Power tools,Electronic vehicles etc.
Protective Function:
1.Battery overcharge function:Charge the battery between P+ and P- to charge the battery. When the voltage is charged to 4.25±0.05V (can be designed according to requirements), the protection circuit operates to shut off the charging path to achieve overcharge protection.
2.Battery over-discharge protection function:Connect the load between P+ and P- to discharge the battery. When the battery voltage drops to 2.5±0.1V (can be designed according to requirements), the protection circuit will act and turn off the discharge path to achieve overdischarge protection.
3.Short circuit protection function:When P+ and P- are short-circuited, the protection circuit will quickly act within 5-50uS, cut off the path, and achieve short circuit protection.
4. Over-current protection function: When the B-side and P-side voltages reach (0.15±0.02V), the protection circuit will quickly act within 5-26ms to cut off the path and achieve over-current protection.
5.Temperature protection:When the product temperature reaches the operating temperature, the temperature control switch will cut off the line to achieve the role of temperature protection.
