Summary
The Gyrfalcon S8000 is a powerful charger that targets professional users. It allows you to set many detailed options to adjust the charging and discharging process. And it performs really good in charging and discharging batteries!
On the other hand it doesn’t feel quite finished. The firmware got improved a lot over my testing period, but there’s still room for improvement and extension. There are a few mechanical usability problems with the terminals as well.
It is quite obvious that Enova took more than a single look at the SkyRC MC3000 when designing the S8000. It has a similar appearance, similar menu and the manual is almost identical. However it still lacks some features to be a real competitor. So far it is more like an “MC3000 light” – but with the potential for improvement!
You mean Li-ion with integrated step-down converter? They usually require their own special "charger", there's no universal standard.
