    China CRAP, don’t buy it.
  

*by T***E on Reviewed in the United States on October 6, 2020*

These things are crap. Used on 30 amps and metal three of them. Don’t buy it. Go up to 100 amp with heat sync for a couple buck more and you won’t ever have issues.

    May struggle with inductive loads. Will fail until balances battery
  

*by T***Z on Reviewed in the United States on July 28, 2021*

Few important observations1. if you plan to use this with inductive load, compensate the load with capacitors. otherwise the unit may randomly refuse to work, shutting off power.2. when the unit shuts off power, the only way to "reset" the balancer is to start charging it, ie. turning the unit off and on will not do anything.3. whatever your plan is, once you get the cells connected to the balancer, give the balancer time to do its job, eg. leave it be for a night or two, even if your cells are all charged. otherwise you will again run into random power shut-off even with regular load (that's actually good, prevents undervoltage).The HX-4S-F30A is not made to specs (search the web for details), but it seems to be doing alright once the load inductance and the cells making your pack are balanced.It is reported that the unit allows battery overcharge so be careful.Performs well with 18650 given enough time to get the initial work done.

    Female Connector NOT Attached
  

*by R***. on Reviewed in the United States on March 14, 2024*

Summary here misrepresents the product slightly - the female connector isn’t actually attached.  If you can solder or have a different method or dont need the connector, this may work.  I chose this partially because of the attached female connector, making this useless for me.  See attached.
