Habe schon 2 Mal einen Kurzschluss verursacht und das Board hat sofort abgeschaltet. Überladen ist auch nicht möglich,
da das Board zuverlässig gegen Überladung schützt.

No manual added.
Tested with 12/24v dc motor. Battery pack conf. is 4S 1P.
Wires in socket all messed up (wrong colours).
Charging tested with 16.8v 2a charger for li-ion batteries but it just won't charger, BUT I guess the charger is faulty, because if I connect just power supply, it charges.

Hab das Board ein zweites Mal bestellt, da ich mit dem ersten sehr zufrieden war.
Das Board kam an, habe es angeschlossen und dann raucht das Kabel ab. Hab dann das andere Board angeschlossen und alles funktioniert.
Meine Schlussfolgerungen: das Board ist kaputt.
Also beim Anschließen aufpassen und sofort reagieren, wenn soewtas passiert

5.0 out of 5 stars Works great.
Reviewed in the United States on 1 June 2020
Verified Purchase
I used the included thin wire connector for the monitoring/balancing connections, and soldered on 18 awg wire for the B-, B+, P-, and P+ points. At first I thought the BMS wasn't working, because all of my connections were correct, but the output wasn't turning on. Then I remembered that some BMSs don't reset until they detect a charger, so I hooked up my 16.8V charger. That worked to reset the BMS, and the output has been reliable. I only run this with a 20 watt load, around 1.5A max, and it has been great.

Ho recuperato dei vecchi pacchi batterie al litio da 3,7 V e collegandoli in serie con questo bilanciatore sono riuscito a costruire una batteria da 14,8 Volt 10 ampere. Il circuito permette la carica bilanciata dei singoli pacchi, evitando il sovraccarico ed il rischio di esplosione.
