  • Double-color LEDs can show the charging progress (RED: charging; GREEN: full).
  • This charger is small and lightweight, and it has a unique balance port for each rechargeable battery.


  • Only utilize LiPo battery types with the charger. Never try to charge any other kind of battery. LiFe, Lilo, or NiMh/NiCd batteries cannot be charged using this charger. Pay attention to any warnings and cautions that came with your battery.
  • Never use a charger alone or unattended. Terminate the process immediately if any errors are seen.
  • Avoid exposing the charger to moisture, dust, filth, heat, glare from the sun, and vibration. Don't let it fall.
  • Check all connections once more before beginning the charging process. Reverse polarity should not be connected.
  • A heat-resistant, non-flammable, non-conductive surface should be used for both the charger and the battery to be charged.
  • Never put them on a carpet, a vehicle seat, or anything similar. Keep explosive and flammable substances far from the working area.
  • We advise utilizing a LiPo charging safety bag, which is readily available from most hobby merchants when charging LiPo batteries.
  • Never charge a LiPo battery that has undergone any sort of swelling.
  • Always connect the adapters cord to the charger first, and only then to the battery that needs to be charged, to prevent short-circuits between the input and output power adapter cord connections. Switch the order around while disconnecting.

Frequently Asked Questions 

Question. How does the B3 charger work?

Answer. The B3 is a straightforward device to operate. To get started, plug it into a power source and the three green LEDs will turn on, then briefly switch to red to show that the charger is prepared. Then, attach the balance lead of the battery to the balance port of the B3. After a 2-second delay, the charger will automatically detect the voltage of the battery and initiate the charging process.

Question. How to charge a 3-cell LiPo battery?

Answer. The most secure method for charging a lipo battery and the one that minimizes stress on the battery is to charge at a rate of 1C, which means that the current will take 1 hour to fully charge the battery, assuming it has a starting voltage of around 3.2v and is completely drained. This charge rate of 1C is equivalent to charging the entire capacity of the battery in 1 hour
