Chargers & Battery Protection

Discover our range of battery chargers, ensuring a safe and efficient charging experience.
It will come in handy, especially for lithium batteries, as they are not always completely tolerant. They are charged using a specific method called CV/CC (constant voltage/constant current), ensuring a consistent voltage while limiting the maximum current.

Explore our selection of protective modules designed to safeguard your battery from potential short circuits when connected to other components. 
They are designed to:
–⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ disconnect batteries in the presence of excessive discharge,
–⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ safeguard against overcharging,
–⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ prevent discharge by disconnecting batteries if their voltage drops below a set value,
–⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ monitor specific charging current thresholds via current limiting.

When selecting a charger or designing a protection circuit, it is important to think about the specifics of your project. What current do you need? How long will the battery charge? What is the maximum allowable charge? These are all questions you should know the answer to.

You can also find protection modules that protect a battery connected to another component from short circuiting. Protection circuits help keep batteries within safe limits. These circuits monitor the voltage, current and temperature of the battery.

Can:

  • disconnect the batteries if it detects too much power,
  • protect against overcharging,
  • protect against discharge by disconnecting the batteries if their voltage drops below a certain value and overcurrent protection, which controls a certain limit of charging current.
