Leider kann das "Ding" nicht was es verspricht.
Ich habe einen Handstaubsauger von NI Cad Akku auf Li-Ion Akku umgebaut. Dazu hatte ich ein Original Li-Ion Ladegerät (von einem neuen Staubsauger) aber keine Lade- und Enladeelektronik. Hab mir dann DIESE gekauft und den Staubsauger umgebaut. Dann kam die große Enttäuschung.
1. WICHTIG Es gibt dazu KEINEN Schaltplan.
2. Ich habe dann diese Elektronik lt. Rezension eines Käufers angeschlossen und diese war nach ca. 1 Min Betrieb kaputt. Offensichtlich vertragen einige Bauteile den Motorstrom von 6,8 A nicht aus. Lt. Daten in der Produktbeschreibung sollten es 10 A sein.
3. Ich habe dann ein neues verwendet und auch beim Laden werden die Bauteile so heiß, dass man sie nicht mehr anfassen kann. Vermutlich würde der Staubsauger dann irgendwann mal abbrennen. Und das bei einem Ladestrom von 179 mA.
Anschluss: auf P+ und P- sind das Ladekabel und der Motor angeschlossen
auf B+ und B- sind der Plus Pol bzw. der Minus Pol der beiden in Serie geschalteten Akkus angeschlossen. An der Verbindung der beiden Akkus ( Minus mit Plus) ist als Abzapfung BM angeschlossen.

Ergebnis: Ich werde das "Ding" als Elektronikschrott entsorgen.

A differenza di quelli economici questi funzionano, e tutti e 5: hanno il bilanciamento, funzionano da subito anche con le sole batterie collegate senza ponticellare o dare impulsi strani, e non appena date in input anche gli 8.4V inizia a caricare ed alimentare allo stesso tempo. Funziona sia la protezione in carica che in scarica.

Spedizione perfetta come sempre. Imballaggio integro e merce sana. Il problema è che di cinque solo uno era funzionante. Gli altri erano già in cortocircuito.
