Frequently Asked Questions

1. How do you use a B3 LiPo charger?

  • Simply plug the B3 into a wall outlet, and the three LEDs will light up green before flashing red to indicate that the charger is ready. Connect your battery's balance lead to the charger's balance port; the charger detects the battery's voltage and begins charging after 2 seconds.

2. Why is the red light on my LiPo battery charger blinking?

  • If charging is required, drain the batteries briefly before attempting again. The battery voltage is too low if the light blinks red after 90 seconds of battery insertion. Leave the batteries in the charger for about 24 hours while the light continues to blink red. After that, take out the battery and try again.

3. How does LiPo battery work?

  • LiPo's work on the principle of lithium-ion intercalation and de-intercalation between a positive electrode and a negative electrode, with a conductive medium provided by a liquid electrolyte.

4. What does the blinking LED lights mean on a battery charger?

  • The blinking LEDs indicate the different charge statuses: Short green flash indicates that the battery is less than 80% charged. A long green flash indicates that you are more than 80% charged. 100 percent charged = solid green light.

5. How can you tell if a battery charger is working?

  • To test the charger's output, connect the battery to the charger and turn on the charger. The meter should read near or equal to the battery's rated voltage. If it doesn't, the charger fails. It is also a good idea to test the charger's current output.
