No instructions in power converters

No instructions or wiring diagram, can't connect as I don't know the required connection order and don't want to blow up the board.

Pros
  • Durable test results
Cons
  • Ugly packaging

Works perfectly. in power converters

so far, so good! I haven't loaded it heavily, maybe 20 amps, but so far it's working fine. Cells remain balanced, do not overcharge or discharge.

Pros
  • handy thing
Cons
  • something else

P+ and P- not working

My P+ and P- have no power after everything is connected. Check the board, it is ok and the soldering is good. I see another review where someone had the same problem. Why is there no continuity at points P+ and P-?

Pros
  • Slim design
Cons
  • Clean

I don't think the Balanced Charge feature works.

Made a 6S battery with this BMS, played with a little bluetooth booster for a few hours, hooked up a 24v (29 volt) charger and when the charge indicator turned green, nothing worked. All 18650 checked, three with near zero voltage and three with 4.6 volts? Connected like in the picture.

Pros
  • Best
Cons
  • Good but not great

Works but questionable quality, solder pads come loose and move when trying to solder wires.

Update: Changed to 4 stars after charging and using the battery pack I assembled, the battery charges correctly and evenly and shuts off at the correct voltage. I'm still not sure how easy it is to detach the pads, but I'd try this board again if I build another 6S block. Some pads on the board actually moved when trying to solder the wires. They seem to reconnect when the heat is removed, I don't know if they are all electrically conductive and if the board is charging the battery properly…

Pros
  • cool product
Cons
  • Zero
