B3 pro lipo charger not working


Junior Member
Hey guys, so I recently ordered I Imax B3 lipo charger from the flite test store and from the second I plugged it in, it started showing issues. Does anyone know what the problem is? Do you know if I can get a refund? If not, what charger do you recommend? (I am trying to get it for under 30 dollars)

No, no, no, no, no!

You want a balance charger with a display. You want to be able to monitor the battery voltage (and other things) while it charges.

I'm not recommending this seller... but this is the style I've bought in the past.


You'll need to find a way to power it. I was able to pick up some power supplies from the thrift store with the right voltage and amp output and with the right polarity/size connector.

This one from Flite Test has the power supply built in.
