I would like to ask advice from some serious racers, is this charger worth the money to invest ? Looks like it has a lot of features but just wonder if we ever need it ?

I understand that during the older batt era, a good charger does play an important part to ensure the batt give the extra punch. Is this the same now tih the new lipos ? Is fast charging the lipo a safe thing to do ?

Any feedback appreciated.

Tks.
