If you have smart batteries or are new to lipos it's a nice addition. You have to store lipos at half power and this charger will put any battery in storage mode. But beware that there is no power supply and will need to have a 7-32 vdc power supply. Spektrum sells one or use an led one. You can also use a battery to power it.
Works great it the display is shows you everything while it’s on all you got to do is plug it in and it does the rest ya it’s smart good product for sure thanks
