I have been supplying lipo balancers thru a LSH for awhile. Recently, the LHS call me up to informed me that a customer returned a 3s balancer for refund complaining that ic chip and fet missing. And claimed that the pack was not open.
On close inspection, the packet was open. There were desoldering marks.(The components were removed by using SMT) Without the ic and fet, the balancer cannot be calibrated. 2 major components missing. Record shows the balancer in question was calibrated, and there were physical evidence as well.
If anyone here wants to know the Fet value and the ic number just ask and I will provide it. If u need a few pieces of it, write to the manufacturer and they would be happy to provide the samples. Don't need to lower yourself to the curb.
