You will find that the B6 50W charger has about 100 different clones that look exactly the same. Even some of the more expensive ones like Losi and Venom are the same hardware.

The thing that is deceiving about those 50W chargers is that they say they can charge up to 6s, and they say they can charge up to 10A, so it looks pretty capable. The problem is based on the 50W rating they can't do both at the same time.

So your lower voltage packs you might be able to charge at 1C, but get into 4-6s packs and you won't be able to. I = P/E, so you can only charge a 4s (16.8v) pack at 3A on a 50W charger, and that is the max theoretical value. Taking into account efficiency and losses you might only be able to charge at 2.5A or less without overheating. Go up to 5-6s packs and your available current will be even less.
